CATV & L-Band Satellite Optical Transmitter SAT-2600

CATV & L-Band Satellite Optical Transmitter SAT-2600
  • Summary
  • Features
  • Advantage
    This series of 950~2600MHz Satellite and CATV optical transmitters work at bandwidth of both 40~860MHz and 950~2600MHz.being able to work independently at bandwidth of 950~2600MHz.  It can transmit CATV signal and the whole L-Band satellite signal(SAT-IF)received by LNB into optical signal, thus achieving transparent transmission of high quality in long distance through fiber. This series is a combination of high technology of CATV and satellite L-Band optical fiber link products, which provides the lowest cost solution in the market for the network providers.
     
    The transmitter is of 1U height which can be easily installed at 19" rack, it adopts low noise, narrow bandwidth and continuous wave DFB lasers with thermoelectric cooler from JDSU, Fujitsu or MITSUBISHI. Adopting original  high quality  critical components and system optimization control technology and SMNP technology designed by our own, the technical parameter of the whole machine completely meet the standard of other like products imported from Europe and U.S.A, providing remarkable photo, digital and compressed digital signals in long-distance transmission for CATV and satellite communication.
