A cable operator opted for FTTH Deployment

Télédistal is a cable operator based in the French part of Switzerland near Lausanne. To extend its networks to housing communities Télédistal opted for a fiber network to deliver existing CATV services at a competitive cost, minimising operating costs, and at the same time future proofing its network. Télédistal selected EMC Electronic Media Communication SA and Nexans as the perfect team to furnish end-to-end solution for its fiber network.

The project
The existing layout of the network delivers broadcast television services from a primary hub location to curbside fibre nodes. From there, the project consisted in connecting the neighbourhood housing communities totalling 280 residents. About 120 are single family homes, the remaining 160 are mainly multi-dwelling units.

Fibre - the best choice
To reduce costs and constraints due to amplifiers exploitation, Télédistal selected the EMC's SUBONET System. In collaboration with Nexans, a complete fiber-optic solution was deployed.

The EMC SUBONET architecture employs concepts familiar to HFC practitioners. The Fibre Hub feeds homes with broadcast TV while upstream signals are summed and transmitted back to the headend. At the subscriber's home a Home Termination Unit incorporating the fibre splicing module performs the signal conversion in both directions.

Type of fibre and installation
The new "Fiber'Art" splice protection modules developed by Nexans in response to the new demands and constraints of modern telecommunications networks are being used in the DCSM type bell cable coupling sleeves and the concentrators designed by the EMC company.

Successful cooperation
EMC together with Nexans have jointly been working during the engineering and installation phases of the infrastructure. While Nexans is best kown for designing and manufacturing highly-flexible passive fiber products, EMC is a well established supplier of future-oriented active fiber optic products for fiber-based access infrastructures. Their product assortment ranges from CATV transceiver modules to highly integrated product solutions for FTTH networks. The benefits of working together into the development was evident and ensured a trouble-free deployment of the FTTH infrastructure.

The close working relationship between the two companies ensured that the passive infrastructure and active electronics were consistently designed for to meet customer and timing requirements.
