Product description
Huatai HDBS-4000CW series is integrated 4pcs of SAT-IF CWDM standard wavelength optical transmitters with optical receivers in a casing. Through CWDM, Transmitter 4 ways optical multiplex (TX) or demultiplex (RX) through one fiber. It can be well used in transmitting a satellite VL, VH, HL, HH different polarize 4 way SAT-IF signal. It can be easily operated.
CWDM (rough multiplex) adopts 20nm channel isolation. 1270nm~1610nm have 18 wavelength. It can transmit 18 way optical signal in one fiber through WDM. Because of without regular EDFA amplifier, it is used in small range of satellite data optical distribution to transmit satellite L-Band optical link.
HDBS-4000CW1, CWDM built-in. 4 way optical signal be multipleted or de-multipleted in the chassis and then input (RX)or output (TX) through a SC/ APC which in the front panel or back panel.
HDBS-4000CW4, without built-in CWDM, 4 way optical signal through front panel or back panel's 4 SC/APC to input or output
Adopt outside CWDM-16, can transmit 4pcs HDBS-4000CW4's 16 way signal through a fiber. It can be used in transmitting 4 satellite different polarized 16 ways SAT-IF signal.
HDBS-4000CW series optical transmitter, all of them adopt high linear, no cooling DFB laser, direct modulation. Improved laser APC control to guarantee laser's high living and high reliability operation. TG type optical transmitter with built-in high linear AGC amplify. TO type without IF amplify inside, allow high level input.
