Summary:
1. It is an important equipment to set up CATV HFC networks, and primarily used for TV video signal, digital TV signal, telephone voice signal and data(or compressed data) signal long-distance fiber transmission system.
2. The product uses imported high performance DFB laser transmitter as light source. RF drive adopts RF power digital automatically processing technique and advanced RF pre-distortion circuits developed by our company. The built-in perfect microprocess or automatically monitoring system ensures the excellent function of the product.

Performance Characteristic:
Adopt world-famous company's advanced DFB laser; Maximum optical output power reaches 30mW.
Add advanced RF Pre-distortion circuit. CATV system's most important CTB and CSO index, and C/N index are improved.
Adopt RF digital automatic control technology. It can automatically adjust drive level to make C/N, CTB, CSO index optimum according to the input RF level and the number of channels.
Adopt high performance Gallium Arsenide RF amplifier, let index higher.

Built-in perfect power output automatic control circuit, laser thermoelectricity refrigeration device temperature and automatic control circuit ensure highest output index and longest life.
Built-in microprocessor automatic control circuit makes DFB laser always in best work state.
Front panel blue VFD display, shows various main work status parameters and realizes automatic fault alarm and network management monitor.
For Field model, built-in big power thermostat may allow the device to work under such kind of environment with high temperature difference.
