Description:
?
SR808R is an special equipment developed for CATV HFC two-way BMAN for uplink; It is mainly used to receive reverse transmission of TV image signal, telephone voice signal and data (or compressed data) signal. Automatic power control circuit and high performance multistage band pass filter are used to improve SNR of back channel and ensure the stable RF output level, so the reliability of CATV HFC network uplink is improved. 4 independent optical receiving unit that independently receive,amplify and monitor and with independently adjustable output level are used in 19”1U standard rack; This reasonably structured receiver with high integration density is easy to install and debug.
?
# PHILIPS or E-O detector who’s receiving optical power threshold is low and line SNR is high with low noise and high sensitivity for optical is selected.
# Microwave low-noise tube push-pull circuit with low power consumption, small noise figure, high output level, good nonlinear index is used for RF amplifier circuit.
# The multistage high-performance high-pass filter is added to suppress noise below 25MHZ and raise uplink NPR indexes efficaciously.
# Advanced automatic power control circuit is added to make it easier to debug uplink. When the input optical power is varied from 0dBm to 8dBm, the RF output level is constant reversely.
# As a maximum,4 independent optical receiver module in the 19”1U standard rack; Each optical receiver module receives and amplifies independently.
# Backup data communications interface, it is convenient to connect with network management responder, connecting with network management system.
