Competition Law and Fibre Network Competition Issues

1. Introduction

Fibre networks—particularly FTTH/FTTP, fibre backhaul, dark fibre, ducts, poles and other passive infrastructure—have become critical infrastructure for broadband, cloud services, 5G backhaul, enterprise connectivity and digital services.

Competition concerns arise because fibre deployment requires very high sunk costs, rights of way, ducts, poles, civil works and access to premises. In many geographic areas, duplicating fibre networks may be economically difficult. This can give an incumbent or early network builder substantial market power.

Competition law therefore has to balance two objectives:

1. Preventing exclusionary conduct and exploitation of market power; and
2. Preserving incentives to invest in expensive next-generation fibre infrastructure.

Modern regulatory practice explicitly recognises this balance. For example, Ofcom's 2026–31 framework seeks both network competition and continued investment in gigabit-capable networks.

2. Relevant Competition-Law Framework

Fibre-network competition can potentially engage several branches of competition law.

A. Abuse of Dominant Position

A fibre operator with substantial market power may potentially abuse that position through:

• refusal to provide network access;
• discriminatory access;
• excessive wholesale prices;
• margin squeeze;
• predatory pricing;
• tying or bundling;
• exclusionary rebates;
• degradation of access quality;
• delaying interconnection;
• discriminatory repair or installation;
• withholding technical information.

Under EU law, Article 102 TFEU is particularly important. Comparable principles arise under national competition laws, including Section 4 of India's Competition Act 2002.

B. Agreements and Concerted Practices

Fibre operators may compete at one level while cooperating at another.

Potential issues include:

• sharing fibre infrastructure;
• joint construction;
• geographic allocation;
• reciprocal access arrangements;
• information exchange;
• coordinated wholesale pricing;
• agreements restricting independent network deployment.

Infrastructure sharing is not automatically unlawful. Its treatment depends on whether cooperation produces efficiencies while preserving meaningful competition.

C. Merger Control

Fibre consolidation can occur through:

• acquisition of an ISP;
• acquisition of a fibre-network operator;
• joint ventures;
• acquisition of dark-fibre assets;
• infrastructure-company mergers;
• vertical integration between wholesale and retail broadband providers.

The principal concern is that consolidation may reduce the number of independent networks or strengthen control over an essential bottleneck.

D. Essential-Facility / Access Issues

A fibre network, duct system, pole network or other infrastructure may sometimes possess characteristics of an essential facility.

However, not every important or expensive infrastructure is legally an essential facility. Competition authorities generally have to consider factors such as indispensability, duplication, foreclosure effects and justification for refusal.

3. Major Fibre Network Competition Issues

3.1 Market Definition

The first question is usually:

What is the relevant product and geographic market?

Possible markets include:

• retail broadband;
• wholesale broadband access;
• FTTH/FTTP access;
• dark fibre;
• leased lines;
• backhaul;
• ducts and poles;
• passive infrastructure;
• business connectivity;
• mobile backhaul.

Geographic markets may be:

• national;
• regional;
• metropolitan;
• local;
• postcode-based;
• individual network footprints.

Fibre competition is often highly geographic because a consumer can only choose networks that actually pass the premises.

4. Network Duplication and Infrastructure Bottlenecks

A major competition issue is whether competitors can economically construct their own networks.

Fibre deployment requires:

• excavation;
• ducts;
• poles;
• street cabinets;
• fibre cables;
• rights of way;
• building access;
• municipal permissions;
• installation labour.

Consequently, an incumbent with an extensive duct or pole network may possess a significant structural advantage.

The European Commission has recognised that access to the last-mile infrastructure can be critical to broadband competition.

Ofcom similarly identified the high construction costs of telecom infrastructure as a factor capable of giving existing infrastructure owners a substantial advantage.

5. Refusal to Provide Fibre Access

An incumbent may control:

• ducts;
• poles;
• fibre loops;
• dark fibre;
• exchange facilities;
• backhaul;
• building-entry infrastructure.

A refusal to supply competitors can potentially exclude downstream competitors.

The legal analysis normally asks:

1. Is the operator dominant?
2. Is the infrastructure indispensable or otherwise sufficiently difficult to duplicate?
3. Can the competitor realistically operate without access?
4. Is refusal capable of eliminating effective competition?
5. Is there objective justification?
6. Would compulsory access undermine legitimate investment incentives?

6. Margin Squeeze

This is one of the most important fibre-network competition issues.

Suppose an incumbent sells:

Wholesale fibre access = ₹80

while selling retail broadband at:

Retail price = ₹85

A rival purchasing wholesale access cannot reasonably compete after accounting for its own retail costs.

This may constitute a margin squeeze.

The problem is therefore not necessarily that either price is independently excessive or predatory. The problem is the relationship between the wholesale and retail prices.

7. Discriminatory Access

An integrated fibre operator may supply access to:

• its own retail division;
• affiliated ISPs;
• independent ISPs.

Competition concerns arise where independent competitors receive:

• slower installation;
• inferior repair;
• less favourable technical specifications;
• higher charges;
• lower-quality access;
• delayed provisioning;
• inferior information.

The principle of non-discrimination is particularly important in wholesale-access markets.

8. Quality Degradation

Competition law is not concerned only with price.

A dominant fibre operator could potentially weaken rivals by providing:

• slower provisioning;
• excessive downtime;
• inferior fault repair;
• reduced network capacity;
• delayed upgrades;
• unreliable access interfaces.

This is especially significant because a rival may technically have access to the network while commercially being unable to compete effectively.

Ofcom has imposed quality-of-service obligations on BT/Openreach and found breaches concerning provisioning and repair performance in certain wholesale markets.

9. Dark Fibre Competition

Dark fibre refers broadly to fibre infrastructure that is installed but not necessarily operated with active transmission equipment by the infrastructure provider.

Dark fibre can facilitate competition because an ISP or communications provider can:

• obtain physical fibre capacity;
• install its own equipment;
• control network management;
• differentiate services.

Consequently, refusal to provide dark fibre may have different competitive implications from refusal to provide a fully managed broadband service.

10. Duct and Pole Access

Competition can be improved without forcing rivals to duplicate the entire network.

A competitor may use the incumbent's:

• ducts;
• conduits;
• poles;
• chambers;
• street infrastructure.

It can then install its own fibre.

This can reduce construction costs while preserving infrastructure-level competition.

Ofcom's framework expressly uses physical infrastructure access as a mechanism for facilitating competing next-generation networks.

11. Fibre Network Sharing

Infrastructure sharing can produce substantial efficiencies.

For example:

Operator A + Operator B → jointly construct fibre → share ducts and deployment costs.

Potential benefits include:

• lower investment;
• faster rollout;
• rural connectivity;
• reduced civil works;
• lower environmental disruption.

But competition risks arise if the arrangement becomes a mechanism for:

• market allocation;
• price coordination;
• exclusion of third parties;
• exchange of competitively sensitive information;
• reduction of independent investment.

Thus, network sharing is not inherently anti-competitive; its structure and effects are critical.

12. Exclusive Fibre Agreements

An infrastructure owner may enter into exclusive agreements with:

• apartment complexes;
• housing developers;
• municipalities;
• commercial buildings;
• business parks.

An exclusive arrangement can potentially foreclose competing networks where competitors cannot reasonably reach customers through alternative infrastructure.

The analysis should consider:

• duration;
• geographic scope;
• number of premises affected;
• availability of alternative networks;
• ability to install another network;
• termination rights;
• exclusivity discounts.

13. Fibre Deployment and Predatory Pricing

An established operator might temporarily offer extremely low prices in areas where a new fibre competitor enters.

The competition question is whether the pricing strategy:

• sacrifices profits;
• is below an appropriate cost benchmark;
• has an exclusionary strategy or effect;
• is capable of eliminating an efficient competitor;
• can subsequently be followed by recoupment or other competitive harm.

However, aggressive price competition is not itself unlawful.

14. Fibre Bundling and Tying

A fibre operator might combine broadband with:

• television;
• mobile services;
• cloud services;
• cybersecurity;
• telephone services;
• streaming;
• smart-home services.

Bundling may benefit consumers through lower prices and integrated services.

But where a dominant fibre network is used to leverage market power into another market, competition concerns can arise.

15. Merger and Acquisition Concerns

Fibre consolidation can generate both efficiencies and competitive risks.

Authorities may examine:

Horizontal effects

Two independent fibre networks become one.

Vertical effects

A wholesale fibre network acquires a retail ISP.

Foreclosure

The merged firm may deny or disadvantage rival ISPs.

Input foreclosure

Competitors lose access to a critical fibre input.

Customer foreclosure

The merged entity may restrict competitors' access to important downstream customers.

Loss of infrastructure competition

Two competing fibre networks may become a single network.

16. At Least 6 Important Case Laws

1. Deutsche Telekom AG v European Commission

Case C-280/08 P, Judgment of 14 October 2010

This is one of the most important telecommunications competition cases.

The case concerned access to the incumbent's fixed network, wholesale local-loop charges and retail access prices. The issue was whether the pricing structure created a margin squeeze.

The Court upheld the principle that a dominant undertaking can infringe competition law through a margin squeeze even where the relevant wholesale prices were subject to regulatory approval.

Fibre relevance

The reasoning is highly relevant to FTTH/FTTP because a dominant fibre operator may simultaneously control:

wholesale fibre input + downstream retail broadband.

A regulator-approved wholesale tariff therefore does not necessarily immunise an operator from competition-law scrutiny.

2. Telefónica SA and Telefónica de España SAU v European Commission

Case C-295/12 P, Judgment of 10 July 2014

This case concerned the Spanish broadband-access market and alleged margin squeeze under Article 102 TFEU.

The Court dealt with the relationship between wholesale broadband access and retail broadband services and upheld the Commission's infringement decision on appeal.

Fibre relevance

It demonstrates how competition authorities can examine whether wholesale access conditions leave sufficient economic space for downstream competitors.

The same methodology is potentially relevant to:

• FTTH wholesale;
• fibre bitstream;
• dark fibre;
• leased lines;
• business fibre services.

3. Konkurrensverket v TeliaSonera Sverige AB

Case C-52/09, Judgment of 17 February 2011

TeliaSonera concerned ADSL input services and retail broadband.

The Court explained that a margin squeeze can constitute an abuse where the relationship between wholesale and retail prices is insufficient to allow an equally efficient competitor to compete effectively.

Fibre relevance

Although the case concerned ADSL rather than modern FTTH, its economic reasoning is directly relevant to vertically integrated fibre operators.

For example:

Fibre wholesale price + rival's downstream costs > viable retail price

can create a potential exclusionary margin squeeze.

4. Slovak Telekom a.s. v European Commission

Case T-851/14, Judgment of 13 December 2018

The case involved the Slovak broadband telecommunications market, local-loop access and alleged abuse involving both refusal/access restrictions and margin squeeze.

Fibre relevance

It is particularly useful for analysing incumbent-network strategies involving:

• access conditions;
• wholesale inputs;
• downstream competition;
• margin squeeze;
• exclusion of alternative operators.

It illustrates that access-related conduct can be examined as part of a broader exclusionary strategy rather than as an isolated pricing issue.

5. Orange Polska SA v European Commission

Case C-123/16 P, Judgment of 25 July 2018

This is especially important because it involved the Polish wholesale market for fixed broadband internet access.

The Commission found that Orange had restricted alternative operators' access to wholesale broadband products and local-loop access through conduct including unreasonable contractual conditions, delays, limitations on network access and withholding information necessary for access decisions.

Fibre relevance

The case is highly instructive for modern fibre markets because competition foreclosure may occur through administrative and contractual barriers, not simply through an outright refusal.

Examples in a fibre environment could include:

• repeatedly delaying access negotiations;
• refusing necessary technical information;
• imposing unreasonable access conditions;
• limiting available capacity;
• creating unnecessary procedural barriers.

6. BT/Openreach – Fibre on Demand / NIPSSN Investigation

This is an important UK regulatory enforcement decision, rather than a CJEU judgment.

Ofcom investigated BT's compliance with network-access obligations concerning its Fibre on Demand product during a public-sector tender.

Ofcom found that BT had failed to provide access on an Equivalence of Inputs basis and concluded that BT had breached the applicable SMP condition. BT admitted the contravention and entered into a settlement.

Fibre relevance

The case demonstrates a practical form of non-discrimination/equal-treatment regulation in fibre access.

An incumbent cannot necessarily provide superior access treatment to itself or its preferred operations while competitors receive inferior treatment.

17. Additional Case: Bronner

Oscar Bronner GmbH & Co. KG v Mediaprint

Case C-7/97

Although this was not a fibre-network case, it is important when considering the essential-facilities doctrine.

The Court imposed a demanding standard for requiring a dominant undertaking to provide access to infrastructure.

The principle is significant because competition law should not automatically transform every commercially important infrastructure into a compulsory-access facility.

Fibre relevance

A fibre operator's refusal to share infrastructure should therefore be analysed carefully.

Questions include:

• Is the infrastructure indispensable?
• Can competitors duplicate it?
• Are alternative technical solutions available?
• Is duplication economically feasible?
• Would mandatory access eliminate investment incentives?

This prevents competition law from becoming a general price or infrastructure-regulation mechanism.

18. Indian Competition-Law Perspective

In India, fibre-network issues can arise principally under the Competition Act, 2002, alongside the sectoral telecommunications regulatory framework.

Potentially relevant provisions include:

Section 4

Abuse of dominant position, including:

• unfair or discriminatory conditions;
• unfair or discriminatory prices;
• denial of market access;
• limiting production or technical development;
• leveraging dominance;
• tying/bundling.

Sections 3 and 3(4)

Potentially relevant where competing telecom operators enter into agreements involving:

• infrastructure sharing;
• exclusive arrangements;
• distribution restrictions;
• market allocation;
• information exchange.

Sections 5 and 6

Relevant to combinations involving telecom and fibre infrastructure.

19. Indian Case-Law Relevance

Indian telecommunications competition disputes have historically required consideration of the relationship between CCI jurisdiction and sector-specific telecom regulation.

Cases such as Bharti Airtel Ltd. v Reliance Industries Ltd. illustrate the importance of determining when a telecom-sector dispute should primarily be addressed through the specialised regulatory framework and when competition-law jurisdiction may arise. The CCI records the matter as Case No. 03/2017.

The CCI has also examined fibre backhaul in merger control. In a combination involving telecom infrastructure, the Commission specifically considered the market for passive infrastructure services through fibre-optic networks/backhaul, noting the importance of dark fibre and wholesale access and considering competing fibre networks including BSNL, Jio, Airtel, PowerGrid and RailTel.

This is particularly significant for Indian fibre competition because fibre is increasingly an input not only for fixed broadband but also for:

• mobile backhaul;
• 5G;
• enterprise connectivity;
• data centres;
• cloud services;
• Internet infrastructure.

20. Regulatory Competition vs Competition Law

Fibre markets demonstrate why competition law and sector regulation must operate together.

21. Remedies

Competition authorities and regulators may consider several remedies.

Behavioural remedies

• non-discriminatory access;
• transparent tariffs;
• service-level agreements;
• equal treatment;
• information disclosure;
• accounting separation;
• compliance monitoring.

Structural remedies

In exceptional merger cases:

• divestiture of fibre assets;
• divestiture of customer bases;
• separation of infrastructure businesses;
• creation of independent wholesale entities.

Access remedies

• dark-fibre access;
• duct access;
• pole access;
• bitstream access;
• wholesale fibre access;
• backhaul access.

22. Investment Incentive Problem

A distinctive feature of fibre competition is the build-or-share dilemma.

If a regulator requires an incumbent to provide cheap access to every new fibre network, competitors may prefer purchasing access instead of constructing networks.

But if access is unavailable, an incumbent may obtain substantial bottleneck power.

Therefore, the appropriate framework must balance:

Access competition + infrastructure competition + investment incentives.

Ofcom's current fibre framework expressly seeks to promote both competition and investment in gigabit-capable networks.

23. Emerging Fibre Competition Issues

Future disputes are likely to involve:

1. FTTH/FTTP wholesale access
2. Dark-fibre access
3. Fibre backhaul for 5G
4. Data-centre interconnection
5. Submarine fibre cables
6. International fibre corridors
7. Cloud-provider fibre infrastructure
8. Municipal fibre networks
9. Open-access networks
10. Fibre network sharing
11. Exclusive apartment/building fibre arrangements
12. AI-driven network management
13. Algorithmic wholesale pricing
14. Fibre infrastructure acquisitions
15. Convergence between telecom, cloud and data-centre infrastructure

24. Analytical Framework for a Fibre Competition Case

A competition authority can broadly proceed as follows:

Step 1 — Define the market
↓
Retail broadband / wholesale fibre / dark fibre / ducts / backhaul

Step 2 — Define geographic scope
↓
National / regional / local / network footprint

Step 3 — Assess market power
↓
Market share + network coverage + entry barriers + infrastructure control

Step 4 — Identify conduct
↓
Refusal / discrimination / margin squeeze / tying / exclusivity / predatory pricing

Step 5 — Assess foreclosure
↓
Can rival operators realistically compete?

Step 6 — Examine objective justification and efficiencies
↓
Investment / capacity / technical limitations / legitimate commercial reasons

Step 7 — Assess competitive effects
↓
Prices + quality + innovation + network deployment + consumer choice

Step 8 — Select proportionate remedy
↓
Access / non-discrimination / pricing / behavioural / structural remedy

25. Key Principles from the Case Law

The six principal telecommunications/fibre-related authorities establish several important propositions:

26. Conclusion

Fibre networks occupy a particularly sensitive position in competition law because they are simultaneously competitive products, essential inputs and high-cost infrastructure.

The central competition-law risks are therefore not limited to traditional price fixing. They include:

• control of bottleneck infrastructure;
• refusal or restriction of access;
• discriminatory wholesale treatment;
• margin squeeze;
• excessive or exclusionary pricing;
• exclusive building arrangements;
• fibre-sharing arrangements that facilitate coordination;
• degradation of service quality;
• foreclosure through vertical integration;
• consolidation of competing fibre networks.

The jurisprudence beginning with Deutsche Telekom, Telefónica and TeliaSonera, followed by Slovak Telekom and Orange Polska, provides a strong analytical foundation for examining modern FTTH and fibre-backhaul disputes. The UK Openreach experience further demonstrates the practical importance of equivalence, non-discrimination and wholesale-access obligations in preserving network-level competition.

For India, the principal challenge is to maintain a workable balance between CCI enforcement, sector-specific telecom regulation, infrastructure sharing and incentives for private investment in nationwide fibre deployment. The CCI's treatment of fibre-optic backhaul in combination analysis shows that fibre infrastructure is already relevant to Indian competition assessment.
