CATV Equipments

Optical Receiver

Features:

  1. Optical receiver high responsible, with PIN photoelectric converter.
  2. Optical receiver High precision, with 10 cascade LED display the optical power.
  3. EOC head-end signal input interface is useful for Ethernet access.
  4. Optimization and typical circuit design, the pre adopts SMT process and the post adopts module amplify that made the photo electronic signal transmission fluency.
  5. Power double output, high gain and low distortion.
  6. With AGC, when the input optical power range is -7~+2dBm, the output lever, CTB and CSO are keep constantly.

Optical Transmitter

Is mainly used for long-distance optical fiber transmission of Television Image Signal, Digital TV Signal and Data Signal. In the part of Optical Circuit, famous brand 1550nm DFB Laser and LinBo3 External Modulator is adopted. In the part of RF-steering, Double Microwave Sources SBS Control Technology researched and developed by us independently and advanced RF Pre-distortion Circuit are adopted. Microcomputer Automatic Control system is built in it to make sure the excellent performance. Performance Characteristics
