The HRF-DX HEADEND RF FORWARD PATH SIGNAL ORGANIZERS from Comtech can be used with
The HRF-DX Headend Rf Forward Path Signal Organizers from Comtech is a Headend Equipment. Headend include several equipment such as head-end, rectifiers, digital satellite receivers, transmitters, RF modulators (QAM/QPSK), control modules, servers that receive the signal from satellites and after that, decode, encode, and multiplex the signal to send in fields via fibers to subscribers.
The HRF-Dx headend RF forward path signal organizer family is designed for feeding optical segments with mixed signals composed on the site. The HRF-D1 type splits the broadcast signal into 8 and it is able to add 8 different narrowcast signal to all the outputs. The HRF-D2S type has 2x8 outputs and it works with two different level narrowcast inputs. The level 1 (L1) inputs add 4 different narrowcast channels to all the outputs, while the level 2 (L2) inputs add 4 different narrowcast channels to a dedicated output. This allows to complete the spectrum of one ore more segment with signals originating from the CMTS, SDA, monitoring gateway or a local TV studio. The devices can be powered by the 1U sized HRF-PS type redundant power supply unit.
