satellite optical fiber transmitter 1310/1550nm

satellite optical fiber transmitter 1310/1550nm
  • Summary
  • Features
  • Advantage
    Satellite mid-frequency and cable TV laser transmitter is working when the bandwidth is 40~860MHz and950~2600MHz. It can be working at 950~2600MHzThe satellite mid-frequency optical transmitter independently. And it will convert to the electrical signals from the all L-Band satellite signals which is accepted from CATV and satellite antenna tuners LNB, to make transmission full transparent, high quality and long distance. It reflects the high technology of CATV and satellite L-Band optical fiber link product. This is a solution for network operators to cut costs. The transmitter’s height is 1U, which makes it installed on a 19’’ standard rack. Its main devices use JDUS, Fujitsu, MITSUBISHI serial lasers which contain thermoelectric cooler with low noise and narrow band. Owing to use international brand with my company system optimized control technology and SMNP network control technology, the whole technology function index meets the standard of same imported equipment, to provide high-quality long distance signal transportation of images ,figure and compressed figure.
