      Super Low Power Return Path Optical Receiver TRR7800L


      Overview        TRR7800L low power return path receiver is designed according to the standard of GY/T 194-2003 "optical node technology requirements and measurement methods". TRR7800L low power return path receiver is the preferred product in bi-directional optical transmission system networking.
             TRR7800L low power receiver contains 4 high performance optical detector to receive 4 optical signals and then convert into RF signal respectively, then RF amplify, to achieve four independent RF output. The output can be independently turned off. It has high isolation, excellent performance, flexible configuration, AGC control characteristics. Its built-in microprocessor monitors the key working state and parameters of the equipment in real time and remotely monitors and controls through network management. Features         ● The use of imported high-quality optical receiving devices for photoelectric conversion.
              ● Using high-performance dynamic noise isolation switch (DNIS switch optional).
              ● 5~200MHz RF bandwidth, to meet the requirements of different CATV system.
              ● Using high-quality low-power reverse amplification module to improve the reliability of the machine.
              ● RFoG and Normal working mode optional.
              ● high-quality switching power supply, to adapt to a wide range of voltage with high reliability.
              ● perfect safety protection circuit (over-voltage, lightning protection).
              ● perfect LCD display control and RS232 status monitoring port, can be easily controlled by computer. Technical Specifications
