What do you understand by RF Overlay for TV services? Explain. |
|
Answer» The TV signals (derived from a satellite Head End) are optionally broadcasted on a third optical wavelength of 1550 nm on same (or additional) fiber introduced into the FTTx system through an RF Overlay sub-system. CATV Signal can be coupled with GPON signal after amplification by EDFA. The RF CATV signals modulated onto the 1550 nm wavelength. It is extracted through a Demux function built inside ONT and routed to back plane service connection for the STB/TV. |
