Product Description
Product Description
HDS-26A series, adopts high linearity with cooling DFB laser and direct modulated way. It can transmit 47~862MHz CATV and 950~2600MHz SAT-IF live-broadcasting TV signal at one fiber.
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 adopts 1U 19 ″ standard 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. Overall unit build in perfect laser APC, ATC control circuit, which ensures the laser long life time and high reliability work. Standard RS232 communication interface, SNMP support telecommunication network management and function.
The SAT-IF adopts high-linearity IF drive amplifying circuit with AGC function, TG type. also optionally, Non-IF amplifying circuit, TO type. TO type can allow high level input. CATV adopts pre-distortion compensation circuit, to improve 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.
