    • Catvision OTU-13 D Series Optic Transmitters use directly modulated DFB
      technology for transmission of optic signal at 1310nm wavelength. A powerdoubler
      amplifier with built-in AGC circuit is incorporated providing a stable RF
      signal with excellent C/N, CSO & CTB performance for long haul transmission.
      These are suitable for both analog and digital Cable TV networks.
      Catvision optic transmitters incorporate a thermo-electric cooler and auto control
      for laser power & bias current to ensure stable optic output power and longer life
      of laser module.Specification
