CONWAY, S.C. -- 4Cable TV Inc has today introduced the first in a line of RFoG Extenders designed to allow the Cable Operator to extend their FTTH; using RFoG, (RF over Glass) deployment further away from the headend. In traditional RFoG deployment fibers are run from a central locations , such as a headend, limiting the distance that the system can be deployed. With the RFoG Extender, Fiber can be run from the headend to a distant location where the RFoG Extender amplifies the incoming light and then splits it in up to 8 separate paths to feed customer taps. The unit simultaneously accepts the 1310 return from the customer’s home, processes it and returns it, on the same fiber or an additional fiber back to the head end and the CMTS.

The unit is housed in a strand mounted outdoor aluminum housing, is powered by 40-90 VAC and is capable of operating in temperatures from -40° to +140°F. The return portion of the RFoG Extender is capable of processing a return signal of -26 dBm while delivering a minimum of 30 dB C/N.

RFoG is a FTTH (Fiber to the Home) solution that allows the cable operator to continue using its installed DOCSIS infrastructure while deploying fiber all the way to the customers home. In new builds and extensions, fiber construction is now less expensive to build than Coax extensions and the reliability and bandwidth of the system is dramatically increased. By already having fiber to the home the operator has the additional option of moving to PON or GPON or another platform in the future, without disturbing his existing infrastructure today.
