We are professional manufacture in CATV line in China, we offer CATV splitter, CATV amplifier, CATV optical receiver, CATV optical transmitter, CATV optical optical switch, EDFA and CATV MODULATOR so on.
CATV OPTICAL RECEIVER FEATURE;
1. WT-8600\WT-7500Series 1310nm optical transmitter is the important equipment for building CATV HFC network, which is mainly used in long- distance optical fiber transmission for TV image signal, TV digital signal, telephone TV signals and data signals(compressed date).
2. WT-8600\WT-7500Series 1310nm optical transmitter adopt international famous brand low-noise DFB laser, high performance LiNbO3 external modulator, and RF drive part is with RF power digital auto-operation technology and advance RF pre-distortion circuit developed by our company. On the other hand, it builds in perfect micro-computer auto-monitor system to make sure good performance index of the whole equipment.
3. Since the first 1310nm laser transmitter come into market successfully, the production technology innovates constantly, circuit structure changes a lot and quality index improves much. On the other hand, RF part of WT-8600, WT-7500 Series 1310nm laser transmitter adopt GaAs amplify circuit, all performance indexes take the lead in domestic market and the quality can be comparable to the imported products.
