 Product description Huatai HDS-26A series, adopts high linearity with cooling DFB laser and direct modulated way. It can transmit 45~860MHz and 950~2600MHz analogue CATV and SAT-IF live-broadcasting TV signal at one fiber. Optical operation wavelength is optional as 1310nm and 1550nm.
1550nm optical transmitter, ITU standard wavelength can be selected, suitable for DWDM, to realize network-upgrading and capability-expansion. It can work together with EDFA,YEDFA to amplify the optical power and large-area FTTH coverage. It can be compatible with any FTTx PON tech, for the Triple-play of CTAV (analogue and digital TV), Satellite TV (DVB-S) and internet.
HDS-26A series products adopt 1U 19″casing, the working parameters of the unit are controlled by micro-processor. LCD on the front panel can display the working status and failure diagnosis. Standard RS232 communication interface, SNMP function. Build-in perfect laser APC, ATC control circuit, which ensures long lift time and reliability of the laser. SAT-IF adopts high-linearity IF drive amplifying circuit with AGC function, TG type. Or optionally, Non-IF amplifying circuit, TO type. TO type can accept high level input. Analogue CATV adopts pre-distortion compensation circuit. Improves system CSO index. It can also guarantee the transmission quality of analogue TV, Digital TV (DBS-C, DBS-T) and satellite TV over single fiber.
