QROR Quad Return Path Optical Receiver

The QROR Quad Return Path Optical Receiver 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 increasing depth of segmentation justifies more and more return path optical receivers at the headend. Since the space is limited in a rack, COMTECH has developed the QROR optical to RF converter with 4 channels to provide improved receiver density. The channels can be used independently or can form 2 redundant channel pairs. The automatic gain control can be switched off in order to serve burst mode RFoG networks, while using the Fiber Deep option a single rack will be able to receive even 384 reverse path channels, which are rendered into 48 separate segments. The device provides the standard COMTECH local management interface and a programmable RF testpoint on the frontal surface.
