Fibre Rollout Bochum 2026: GELSEN-NET and Ruhr Valley Infrastructure
Fibre Rollout Bochum 2026: GELSEN-NET Advances FTTH Infrastructure in the Ruhr Valley
The fibre rollout in Bochum by GELSEN-NET marks a turning point for FTTH infrastructure in the Ruhr Valley: by end of 2026, over 50,000 households in Bochum will have direct access to fibre optic connections, while backbone networks are simultaneously being expanded with high-density splice systems for up to 288 fibres. Technical implementation requires precisely coordinated components from the main distribution point to the building connection, with modular splice boxes accommodating 96 fibres in 1RU forming the critical infrastructure.
As a municipal network operator, GELSEN-NET is deploying future-proof system solutions for fibre rollout that meet rising bandwidth demands for decades to come. The challenge lies not only in laying fibre optic cables, but above all in efficient distribution and management of fibres within network distribution frames.
Technical Requirements for FTTH Rollout in Bochum
Fibre rollout in Bochum presents special demands on splice technology in use. At main distribution stations, up to 1,728 fibres must be terminated in minimal space. This requires high-density splice systems that are simultaneously service-friendly and standards-compliant to IEC 61754.
GELSEN-NET’s technical planning provides for a three-tier network architecture: from central backbone through local exchange points to building termination points. Each tier requires specific splice solutions with different packing densities and connector types.
- Backbone tier: MPO/MTP connectors for 12 to 72 fibres
- Distribution network: LC-APC duplex with attenuation < 0.25 dB
- Building connection: SC-APC simplex for individual fibre connections
- Redundant links: E2000-APC with enhanced return loss
GELSEN-NET Network Strategy for FTTH in the Ruhr Valley
GELSEN-NET’s strategy for fibre rollout in Bochum is based on systematic densification of the existing network. Previously installed empty ducts are being equipped with modern micro-cables capable of accommodating up to 288 individual fibres. This high fibre density requires correspondingly powerful splice systems in distribution cabinets.
| Expansion Phase | Timeline | Households | Fibre Density | Splice System |
|---|---|---|---|---|
| Phase 1 | Q1–Q2 2026 | 15,000 | 96 fibres | 1RU module |
| Phase 2 | Q3–Q4 2026 | 20,000 | 144 fibres | 2RU module |
| Phase 3 | Q1 2027 | 15,000 | 288 fibres | 3RU/4RU systems |
The modular design of the splice boxes used enables staged expansion without service interruption. This is particularly important for continuous supply to already-connected customers during the expansion phase.
Splice Technology and Distribution Systems in Municipal Fibre Networks
For municipal network operators like GELSEN-NET, selecting the right splice technology is critical to the economic success of FTTH rollout. Investment in high-quality splice modules with 5-year warranty reduces operational costs in the long term through lower failure rates and simplified maintenance.
Modern splice systems must meet diverse requirements: they must achieve high packing density of 96 fibres in 1RU while remaining service-friendly. Accessibility to individual fibres without compromising adjacent connections is essential.

Standards Compliance and Quality Assurance in Bochum Fibre Rollout
GELSEN-NET maintains strict compliance with international standards for FTTH Ruhr Valley rollout. All components must meet standards IEC 61300 for optical connectors and IEC 61754 for connector faces. Attenuation values must not exceed 0.25 dB for LC connectors.
Return loss for APC connectors must be at least 60 dB to prevent signal interference in high-speed transmission links. These strict requirements guarantee future-proof infrastructure for upcoming transmission standards up to 400 Gigabit.
Additionally, GELSEN-NET requires compliance with fire safety standard EN 50575 for all in-building components. Splice boxes must meet fire classification Dca-s2,d2,a1 to minimise fire and smoke spread in emergencies.
Challenges of Urban Fibre Installation in the Ruhr Valley
Fibre rollout in Bochum faces specific challenges of the densely populated Ruhr Valley region. Existing underground infrastructure of gas, water and electricity lines complicates route planning. GELSEN-NET therefore employs minimally invasive installation techniques such as trenching with just 10 cm slot width.
- Micro-cable blowing-in technique through existing empty ducts
- Horizontal directional drilling beneath main traffic roads
- Building entry via existing utility shafts
- Coordination with other utilities for joint use of routes
High building density requires compact distribution cabinets with maximum fibre density. Here modular splice systems come into use, enabling termination of up to 288 fibres in minimal space. Cabinets are preferably integrated into existing equipment rooms or basement areas.
Investment Volume and Economic Viability of FTTH Rollout
GELSEN-NET is investing an estimated total of €75 million in fibre rollout for Bochum. Approximately 20 percent is allocated to passive network infrastructure including splice technology and distribution systems. Choosing high-quality components with extended warranty periods significantly reduces lifecycle costs.
| Cost Item | Share | Investment | Amortisation |
|---|---|---|---|
| Civil works | 60% | €45m | 25 years |
| Fibre cable | 15% | €11.25m | 30 years |
| Splice technology | 10% | €7.5m | 20 years |
| Active equipment | 10% | €7.5m | 7 years |
| Planning/documentation | 5% | €3.75m | – |
Refinancing occurs through monthly connection fees averaging €40 to €60 per customer. At an anticipated uptake rate of 40 percent, the investment amortises within 12 to 15 years.
