Description
BD-OP-SAT satellite optical transmitter adopts high linearity cooling DFB laser, direct modulated. Realize the simultaneous transmission of 47-862MHz CATV signal and 960~2600MHz satellite direct TV signal in one optical fiber.
BD-OP-SAT satellite optical transmitter can use ITU standard wave length and DWDM to realize network upgrade and expansion. Its optical power can be amplified by EDFA and YEDFA, achieve large area FTTH. It can be compatible with FTTxPON technology to realize FTTH and the multi-network integration of CATV (Analog and Digital TV), Satellite Television (DVB-S) and Internet.
BD-OP-SAT adopts 1U 19” standard rack, microprocessor controls the working parameters, front panel LCD provides status display and fault diagnosis. Standard RJ45 communication interface, with SNMP network management function. Built-in perfect laser APC and ATC control circuit to ensure the long working life and high reliable work of the laser.
SAT-IF adopts high linearity IF driving amplifier circuit with AGC function to ensure the high quality transmission of Analog TV, Digital TV (DVB-C, DVB-T) and Satellite TV in one optical fiber.
