FWT-2600 series of 950~2600MHz Satellite optical transmitters work at bandwidth of 950~2600MHz, FWT-2600 can transmit the whole L-Band satellite signal(SAT-IF)received by LNB into optical signal, thus achieving transparent transmittion of high quality in long distance through fiber.
FWT-2600 series is a combination of high technology of CATV and satellite L-Band optical fiber link products, which provides the lowest cost solution in the market for the network providers.
The transmitter is of 1U height which can be easily installed at 19" rack, it adopts low noise, narrow bandwidth and continuous wave DFB lasers with thermoelectric cooler from JDSU, Fujitsu or MITSUBISHI. Adopting original high quality critical components and system optimization control technology and SMNP technology designed by our own, the technical parameter of the whole machine completely meet the standard of other like products imported from Europe and U.S.A, providing remarkable photo, digital and compressed digital signals in long-distance transmittion for satellite communication.
