fiber in the home (FITH)

Fiber in the Home (FITH) is the logical continuation of Fiber to the Home (FTTH) in the home network. With FTTH, monomode fibers are laid from the point of presence( PoP) in the local exchange to the house transfer point(HÜP). From this point, Fiber in the Home (FITH) is about in- home cabling, which is implemented with polymer fib ers. The polymer fibers are laid in the individual apartments and rooms and terminate at the optical outlets to which the subscriber terminals are connected.

The polymer fibers laid in Fiber in the Home have sufficient transmission capacity to be able to display modern broadband services such as Internet telephony, video on demand, video telephony, computer games, Internet radio and Internet TV up to ultra HDTV. Other areas of application include smart homes and IP-enabledalarm systems with IP cameras.

The services from broadband cable, VDSL and FTTH provided at the home delivery point are routed to the optical outlets via polymer fibers. The available data rates for broadband cable are several hundred Mbit/s, for VDSL they are 50 Mbit/s, in some cases even 100 Mbit/s, and for FTTH the data rates can reach up to 1 Gbit/s.

As for the FITH structure, the aforementioned broadband services are routed via an access router to an optical switch, which splits them into multiple signal paths according to the number of optical outlets. The polymer fibers then extend in a star configuration directly from the optical switch to the connection outlets. The end devices - PCs, TVs, tuners - can be connected via optical patch cables or WLANs.
