CATV Fiber Optic Transmitter

The MX862T series direct modulated transmitter delivers high performance signal transmission of NTSC, PAL, digital or compressed digital information for CATV and/or telephony applications.

Product ID: MX862T Categories: ,
  1. General Details

    The MX862T series direct modulated transmitter delivers high performance signal transmission of NTSC, PAL, digital or compressed digital information for CATV and/or telephony applications. It is based upon custom high-linearity optically isolated DFB (Distributed Feedback) lasers, specifically designed for multi-channel AM video applications. Automatic output power control, coupled with temperature stabilization provided by a thermoelectric cooler ensures maximum performance and longer laser life. The units are packaged in slim 1.75-inch high, 19-inch rack-mounted enclosures. Each unit is fitted with a self-contained power supply with 110 VAC input.

    All internal laser parameters and monitoring functions are under microprocessor control: the front panel VFD displays select information related to laser operation. Alarm relay contacts in the back of the units provide remote warning in the case of a disabled transmitter.
