4Cable TV has introduced the first in a line of RFoG Extenders designed to allow cable operators to extend fiber to the home (FTTH), using RF over Glass (RFoG) deployment further away from the headend. In standard RFoG deployment, fibers are run from a central location, such as a headend. 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 eight separate paths to feed customer taps. The unit simultaneously accepts the 1,310 nm return from the customer’s home, processes it, and returns it on the same fiber or an additional fiber back to the headend 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 degrees 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 CNR.
