TOS2000TFR series return path receiver module is the first choice for bi-directional optical transmission system (CMTS) ,  including four high-performance optical detectors, which are used to receive four 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.

　　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.Independent return optical receiving channel, up to 4 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 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.
