Product Description

Description 
1550nm Direct Modulation Optical Transmitter (DT-DMOT-1550-20KM) series DWDM wavelength QAM optical transmitter is a high specification optical transmitter, which adapts to cable digital television development. It can be used to transmit cable digital television and data broadcast, DVB QAM signal long distance fiber.
This optical transmitter operation wavelength complies with ITU-T G.692 standard. It can transmit more than 40 wavelength channels with DWDM technology in one fiber at the same time, and can input 64 QAM, 256 QAM, QPSK digital modulation signals within bandwidth of 47~860 MHz.Input RF power:80dBμV,Operation bandwidth:47~862MHz,C/N:54dB,CSO:68dB,CTB:68dB,European standard plugs or American standard plug is optional.

Features
⊙19" 1U case, easy to install.
⊙More than 40 wavelength choice, it can be added data business at random easily.
⊙Reliaze low-cost resolvent in DVB signal long-distance transmission, DVB city-county union network.  
⊙Low chatter, it can satisfy long distance or short distance fiber transmission RF signal requirement at most.
⊙47~860MHz operation bandwidth can provide usability of flexibly configuring RF channels for subscriber.
 
Application
⊙Cable digital television, VOD, Internet, IP phone, data broadcast.
⊙Apply to standard 64 QAM, 256 QAM or QPSK digital modulation signal transmission.
