CATV 1310nm Fiber Optic Transmitter
The MX1000T series direct modulated transmitter delivers high performance signal transmission of NTSC, PAL, QAM, digital or compressed digital information for CATV applications.
- General Details
The Maxcom MX1000T is a 1310nm direct modulation optical transmitter with high index and AGC function. Maxcom incorporates a high linearity and a low chirp DFB laser, built-in pre-distortion compensation and AGC, APC, ATC closed loop control, which provide an improved performance index. It may be used for cable television applications for transmitting Digital QAM CATV and DOCSIS RF signals over fiber. LED panel display and front panel control.
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 dual self-contained AC power supplies.
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.
