Product Details
1310nm Laser Transmitter (WT-8600)
Product Description
1. Laser Transmitter adopts advanced dfb laser instrument, maximum output optical power reach 30mw add advanced RF pre-distortion circuit, to use as proofreading CATV system most important ctb and cso index,
2. And to improve c/n indexadopts RF digital automatic control technology Transmitters can automatically adjust drive level and make c/n, ctb, cso index always in best state based on input RF level,
3. Number of channels adopts high performance gallium arsenide RF amplifier, let index higher built-in perfect power output automatic control circuit
4. And laser thermo electricity refrigerator temperature automatic control circuit, insures 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,
5. Transmitters shows various main work status parameters and realizes automatic fault alarm and network management monitor.
