| Overview
OPR-9800S return path receiver is the first choice for bi-directional optical transmission system (CMTS) , including eight high-performance optical detectors, which are used to receive eight optical signals and convert them into RF signals respectively, and then carry out RF pre amplification respectively, so as to realize 5-200MHz return path. Each output can be used independently, featured in excellent performance, flexible configuration and automatic control of optical power AGC. Its built-in microprocessor monitors the operating status of the optical receiving module.
Features
(1) Independent return optical receiving channel, up to 8 channels for users to choose, output level can be adjusted independently in optical AGC state, which provides users with great selectivity.
(2) It adopts high performance photo-detector, operating wavelength 1200 ~ 1620nm.
(3) Low noise design, the input range is -25dBm~0dBm.
(4) The operating parameters of the whole machine are controlled by microprocessor, and the LCD status display on the front panel has many functions such as laser status monitoring, parameter display, fault alarm, network management, etc.; once the operating parameters of the laser deviate from the allowed range set by the software, the system will alarm promptly.
(5) Built in dual power supply, automatically switched and hot plug supported.
(6) Standard RJ45 interface is provided, supporting SNMP and web remote network management.
