5 Single-cable Sat TVdistributionusing static dCSS/Unicable LNB RF overlay for Fiber-To-The-Riser & Fiber-To-The-Home deployments Many DTH services are delivered to subscribers homes over a single-cable installs using, for example, a dCSS/Unicable II LNB operating in Static mode. The LNB output RF signal is then distributed over a coax cable to the riser, through the building and inside the homes using simple RF splitters and coaxial cables. Large installations with lots of coax splits, noisy, long or poor quality cables and connectors will require numerous line amplifiers, filters and power inserters to be installed with a high toll on installer time spend at site in order to deliver sufficient signal quality. Upgrading the installation with a fiber-to-the-riser and using a Unifiber transmitting headend will deliver a higher quality signal, save the installer significant time simplify the installation substantially. In this case, the LNB RF signal is connect a 1310nm Unifiber transmitter (DTT signal can be connected and distributed over the same fiber too) and the optical output signal can be distributed over a simple PON to a Unifiber wideband receiver to convert the optical signal back to RF. The RF signal can then be distributed to the homes over the existing coax cables. Optionally, a 1550nm transmitter connected to a Unifiber EDFA can be used to boost the optical signal to reach thousands of homes. Satellite Terrestrial Fiber Unicable II ®
