| Overview
OPR-9235B indoor optical receiver adopts high performance and high efficiency O/E converter. The first stage is amplified full GaAs MMIC, and the second stage by gain GaAS power double module, which ensure high output level. The whole device is controlled by microcomputer; AGC, ATT and EQ are adjusted by numerical control, which is the best choice for the construction of ring network in large and medium-sized cities.
Features
(1) It adopts high performance photo-detector, operating wavelength 1200~1620nm.
(2) Optical AGC control, when input is within range -7~+2dBm, the output level remains unchanged and CTB, COS is measured up to the standard.
(3) High gain, low distortion.
(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.
