Huatai HDBS-5000CW series combines 4 units SAT-IF optical transmitters and 1 unit CATV optical transmitter, or SAT-IF optical receivers that has CWDM standard wavelength into one housing. The built-in CWDM Multiplexing or De-multiplexing the 5-way optic, and transmit via one single fiber, which can transmit four-way SAT-IF signal of VL, VH, HL HH four polarizations and one-way CATV signal in one satellite with a high quality, flexible to install and convenient to use.
CWDM (wide wave multiplexing) adopts 20nm channel distance. There are 18 wavelengths during 1270nm~1610nm. All these 18-way optical signals can be transmitted via one single fiber by WDM. The CWDM cannot amplified by normal type EDFA, it can only apply to a small range satellite FTTH, short distance satellite L-Band optical link.
HDBS-5000CW1 is with built-in CWDM. The 5-way optical signal Multiplexing or De-multiplexing inside the housing, then input (RX) or output (TX) by the SC/APC connector on the front panel or back panel.
HDBS-5000CW5 is without built-in CWDM. The 5-way optical signal input (RX) or output (TX) by the 5 SC/APC connectors on the front panel or back panel. It can transmit 17-way optical signal from 1 unit HDBS-5000CW5 and 3 units HDBS-4000CW4, which can transmit four satellites with 16-way SAF-IF signal of four polarizations and one-way CATV signal.
HDBS-5000CW series optical transmitter adopts un-cooling DFB laser that is featured with high linearity for SAT-IF, cooling DFB laser that is featured with high linearity and direct modulation mode for CATV. The whole unit is installed perfectly with built-in laser APC, ATC control circuit to ensure the laser's long life and high reliability. The CATV adopts the RF AGC driving circuit with pre-distortion compensation. The SAT-IF has high linearity IF amplify circuit with AGC function (TG type) and without IF amplify circuit (TO type) optional. The TO type allows high level input.
