Super Low Powಞer Ret🔯urn Path Optical Receiver TRR7800L


Overview        TRR7800L low power return path receiver is des🔜igned 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, ex👍cellent 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 ma𓂃nagement. Features         ● The use of imported high-quality optical receiving devices for photoelecꦛtric conversion.
        ● ⛄  Using high-performance dynamic noise isolation switch (DNIS switch optional).
        ●  5~200MHz RF bandwidth, to meet the requirements of different CA♈TV꧒ system.
        ● Using high-quality low-power reverse amplification module to improve the re𝓰liability of the machine.
        ● 🎐  ⭕ RFoG and Normal working mode optional. 
        ● high-quality switching power supply, to adapt to a wi🐲de range of voltage with high reliability.
        ●  perfect safety protection circuit (over-voltage, lightning pro𓃲tection).
        ● perfect LCD display control and RS2♏32 status monitoring port, can be easily controlled by computer.  Technical Specifications
