TOS2000TOR forward 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 doubler 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.

　　The product has the characteristics of small size and compact structure, and can be used with TOS2000TEL power supply and TOS2000TJK optical platform to form an optical transmission system with excellent performance.

1.It adopts high performance photo-detector, two operating wavelength specified by user: full 1200～1620nm or 1540～1560nm with filter.

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 built-in microprocessor monitors all the operating status parameters of the module and transmits them to the platform through the bus. The platform can monitor and display its operating status through LCD screen. The intelligent function of the platform provides a good internal operating environment for the module, so that the excellence of the module can be brought into play, with high reliability and stability.
