Consumers require a higher and higher amount of bit rates for Internet, telephone and TV.
The Federal Government of Germany aims to achieve a comprehensive bit rate of 50 MBit/s by 2018. This can be quickly and economically realised by "Fibre to the Curb" technology (FTTC). The DSL switching exchange is located in cable distributors via glass-fibre and connects to the households via copper cables with the network. Rittal has developed multifunctional enclosures for FTTC via which up to 3,600 subscribers can be connected to quick DSL.

FTTC (Fibre to the curb)
The FTTC technology is like all other FTTL technologies where a glass-fibre connection is routed "along the curb" between local exchange and distributor. There, a signal conversion is made via the network unit (ONU) that is located in the distributor and further transmission to the subscriber terminal via copper cable.
Fibre to the Curb (FTTC), also named Fibre to the Cabinet (FTTCab), is predominantly laid in the scope of (regional) broadband expansion in urban areas and used for the VDSL technique. For this purpose glass fibres are laid parallel to the main cable routes and active units, the DSLAM, are installed in cable distributors (KV). The bridgeable distance is approx. 550 m. 32 to 64 broadband accesses are available. The transmission speed is between 2 Mbit/s and 12 Mbit/s in the upstream and between 25 Mbit/s and 52 Mbit/s in the downstream.
