4C86XXAF series of AM laser transmitters deliver high performance signal transmission of NTSC, PAL, digital or compressed digital information for CATV and/or telephony applications. It is based upon a custom high-linearity optically isolated DFB (Distributed Feedback) laser, specifically designed for multi-channel AM video applications. Built-in driver amplifier and control circuits, provide an exceptionally low noise and inter-modulation characteristics. 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 requiring 85-254V AC input.
ALL internal laser parameters and monitoring functions are under microprocessor control; the front panel LCD displays status information related to laser operation. Optional alarm relay contacts in the back of the unit provide remote warning in the case of a disabled transmitter.
