1.2 Product Description
20MM-LT10L satellite optical transmitter adopts a high linearity cooling DFB
laser, direct modulated. Simultaneous transmission of 47-862MHz CATV signal and
950~2600MHz satellite direct TV signal in one optical fiber.
20MM-LT10L satellite optical transmitter can use ITU standard wavelengths and
be integrated with DWDM for Network upgrades and expansion. Its optical power
can be amplified by an EDFA or YEDFA to achieve large area FTTx. It is compatible
with FTTx PON technology to achieve FTTH and the multi-network integration of
CATV (Analogue, DVB-T,T2, DVB-C), Satellite Television (DVB-S/S2) and Internet.
20MM-LT10L is in 1RU 19” standard rack form, with a built in microprocessor
controlling the working parameters via keys and front panel LCD to provide 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 of the laser.
SAT-IF adopts a high linearity IF driving amplifier circuit with AGC function to
ensure high-quality transmission of Analog TV, Digital TV (DVB-C, DVB-T/T2) and
Satellite TV in one optical fiber.
