Huatai VOD1504 is a high performance 1550nm direct modulated inter-cut (narrow-bandwidth multiplex) optical transmitter which design and manufacture specially for realizing two-way television interact operation (VOD) for CATV network, mainly used in second service area to inter-cut IP/QAM or local program. In the content distribute network system (CON), VOD1504 is the VOD flow rate loading equipment, also often called the edge IP/QAM optical transmitter.

Huatai according to the multi-year application experience in inter-cut system designed all the functions for VOD1504 that Overlay need, which make it convenient for customers to apply and debug.

Build-in WDM, realizing the multiplex of main signal and inter-cut optical. The panel with main signal optical input port and join-wave output port can extra simplify the connection.

Build-in electronic-control VOA, customer can set the optical power ratio of inter-cut and main signal according to system demand. After setting, the whole unit system software can in line with the change of main signal optical power, via VOA, adjust the inter-cut output optical power automatically that can make the difference controlled in the range of customer set, extra simplify the system debugging.

Excellent optical modulation degree controlled automatically, can in line with inter-cut channels automatically, keep the modulation degree consistent. For convenient adjustment, inside equipment adds one set manual operation modulate level control circuit (MGC).

VOD1504 adopts high linearity DFB laser. ITU standard wavelength ±1.6nm adjustable. Excellent predistortion compensation, perfect APC,ATC, AWC control, 1+1 power backup, support hot plug. The advanced SNMP network management function, support remote management and control.
