Fibre Optic Alternative
An alternative approach to that provided by single cable distribution of the signal from a single LNB to multiple receivers, or receivers with multiple tuners, is offered by the use of fibre satellite distribution using optical fibre. The high bandwidth of optical connections allows for the full satellite spectrum received at the dish to be accommodated on one fibre optic cable, which can be easily optically split to provide that full spectrum signal to a large number of receivers.
UK company, Global Invacom (which also developed and markets SCR single cable distribution equipment) has developed a low cost system of fibre optic distribution suitable for domestic installations and small or medium commercial communal dish systems, with an optical output LNB, fibre cables, splitters, and converter units to return the optical signal to an electrical one compatible with legacy receivers.
The extremely low signal loss through fibre optic cables and complete elimination of interference and noise picked up by the cable mean that such a system can support very long cable runs between the dish and the converters in a widespread communal dish system, and a smaller dish can be used as the communal antenna.
Global Invacom won the Astra Innovation Contest run by satellite operator SES in 2007 for the proposal and initial development of optical fibre distribution systems for satellite TV.
