Description：

CNOT1310 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. The built-in EDFA 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 with 110-254V AC 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.
