| Overview
OPR-9235T dual inputs indoor optical receiver is featured in short switching time and low loss, which is mainly used in ring network or redundant standby network. When the main line fails or is lower than the set threshold value, it will automatically switch to the standby line. When the main line returns to normal, it will automatically return to the main line. When device is in the mode of manual forced switching, it can switch to the main line or the standby line as you like.
This device 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) Professional RF switching module, short switching time, low loss, with automatic switching and forced manual switching function.
(2) It adopts high performance photo-detector, operating wavelength 1200 ~ 1620nm.
(3) Optical AGC control, when input is within range -7~+2dBm, the output level remains unchanged and CTB, COS is measured up to the standard.
(4) High gain, low distortion.
(5) 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.
(6) Built- in dual power supply, automatically switched and hot plug supported.
(7) Standard RJ45 interface is provided, supporting SNMP and WEB remote network management.
