Product Description

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.
