The ORPR Return Path Receiver is used to receive upstream optical signals and to transport return information to the optical distribution hub or headend.

The ORPR receiving module is designed to convert an optical signal from the node to an electrical RF signal for processing at a hub or headend location. Each receiver can accept audio, video or any combination of these signals. The chassis supports up to four optical receiver modules in a 1U high, 19" rack mount enclosure.

The chassis is powered with 90~265VAC and equipped with several status LEDs and test points to facilitate troubleshooting and maintenance. Each module has a status LED indicator. There is also an RF test point and optical photocurrent test points for each receiver on the front of the chassis. The unit's RF output level can be manually adjusted through the use of an adjustable attenuator located on the front panel.
