Huatai HDBS-4000DW series, combine 4 pieces C-Band, 100GHz, ITU standard wavelength SAT-If optical transmitter, or optical receiver to one chassis, through DWDM, Make 4 ways optical MUX (TX) or DEMUX (RX), through one fiber, used in transmitting 4 ways different polarization SAT-IF signal of one satellite VL, VH, HL, HH with high performance. Installation flexibility.
DWDM technology, C-Band, 100Ghz channel space, it can transmit over than 40 signals with only one fiber. With using EDFA to amplify then realize long distance and large scale FTTH, compatible with CATV and any FTTx PON technology, realize the syncretism between DBS and Triple-play.
HDBS-4000DW1, build in DWDM. 4 ways optical signals be MUX/DEMUX in the casing, through one SC/APC connector equipped in front panel or back panel, realize input (RX) or output (TX).
HDBW-4000DW4, without build-in DWDM, 4 ways optical signal through 4 SC/APC connectors equipped in front panel or back panel for input or output. Adopt external DWDM, make 4 units HDBS-4000DW4 total 16 ways optical signal, using one fiber for transmission. Application in transmit 16 ways different polarization SAT-IF signal of 4 satellites.
HDBS-4000DW optical transmitter, all adopt C-Band, 100Ghz, ITU standard wavelength with tunable high linearity, with cooling DFB laser, internal modulated. With high performance wavelength tunable and stability control circuit, laser work wavelength can be adjusted and steady controlled in ±1.6nm range, output power adjustable, matching with DWDM. Perfect laser's APC, ATC control the circuit, ensure the laser long life and high reliable operation. TG type optical transmitter is build-in high linearity AGC amplification. TO type without build-in IF amplification, allow high level input.
Adopt DWDM, C-Band, 100GHz, ITU standard wavelength, one fiber bear to transmit 4 ways, 8 ways, 16 ways and 32 ways SAT-IF optical signal.
Use EDFA amplifier, realize the long distance and large-scale FTTH.
