Unifiber™ Product Catalogue

6 As the penetration of fiber networks increases, and specifically in new builds, more and more homes are being connected with a fiber cable for the delivery of broadband data and TV services. The Unifiber solution allows installers to utilize the same fiber core that carries the broadband data service to overlay the RF output signal of the LNB and deliver the satellite TV (and DTT) services to subscribers’ homes directly. The output RF signal of the LNB is connected to a 1550nm Unifiber transmitter (DTT signal can be connected and distributed over the same fiber too) whose output is then connected to a Unifiber EDFA device with built-in WDM inputs. The EDFA’s WDM inputs are connected to the equipment of the data service provide in the building and the output ports of the EDFA will then carry both data and TV services over the same fiber core. A common WDM (Wavelength De-Multiplexer) device installed in the subscriber home then separates the data service (usually delivered over 1310nm + 1490nm wavelengths) and the TV services over two independent optical output ports. The data port will be connected to a data optical network termination device (usually a Wi-Fi router provided by the data service provider) while the TV output port will be connected to a Unifiber wideband receiver to convert the optical signal back to RF and distribute it to STBs and TVs around the home over coax cables. In some cases, for redundancy and resiliency purposes, the data service and the TV services will not share the same fiber core but different cores over the same fiber cable. In these cases, a lower-cost 1310nm Unifiber transmitter can be used instead of the 1550nm model, the WDM inputs of the EDFA can be skipped and there will be no need to install a WDM device in the subscriber home.
