Satellite Optical Transmitter
Description BD-OP-SAT satellite optical transmitter ado […]
INFORMATION
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 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.
