Product Description

VOD Overlay 1550nm Drect Modulated Optical Transmitter

Product description
Huatai VOD1504 is a high performance 1550nm direct modulated inter-cut (narrow-bandwidth multiplex) optic 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.

Product features
1. ITU standard wavelength, ± 1.6nm adjustable
2. Build-in WDM, the panel with main signal optical input port and join-wave output port, offer simple connection
3. The difference of main signal input optical power and inter-cut optical power can be set by panel and SNMP
4. Identify and track the main signal optical power automatically, adjust the inter-cut output optical power automatically via VOD, to keep the difference in the range set by customer
5. High performance optical modulation degree auto-control, can keep the modulation degree consistent, in line with inter-cut channels
6. Independent manual operation modulate level control circuit (MGC), make the system convenient to debug
7. High linearity 1550nm DFB laser
8. High performance predistortion correction, excellent APC, ATC, AWC control
9. Low (No) optical input, inter-cut optical shut automatically
10. High performance SNMP network management function, support remote management and control
11.1+1 power backup, support hot plug
12. Industrial excellent cost performance

Main application
1. VOD flow rate loading inter-cut optical transmitter
2. Edge IP/QAM optical transmitter
3. Full optical 1550nm, video data inter-cut operation

Application cases
1. VOD overlay FTTH PON ( single fiber three wavelength)
2. VOD overlay FTTB PON ( single fiber three wavelength)
3. VOD overlay FTTH RFoG( CMTS ) ( single fiber two, four wavelength )
4. VOD overlay FTTB RFoG( CMTS ) ( single fiber two, four wavelength )
5. The desigh and debug of system
6. ITU Grid Channel Table
