Dror Dual Return Path Optical Receiver

The Dror Dual 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.

For handling modulated return path data flows in an up-to-date CATV network a low noise optical receiver with defined and constant output RF level is needed. A DROR module contains 2 optical to RF converters that have the mentioned features, these receivers can be configured for independent or redundant work. 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 192 reverse path channels, which are rendered into 24 separate segments. The device provides the standard COMTECH local management interface and two RF testpoints (each per channel) on the frontal surface.
