  • 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.




     High quality: original system optimization control technology and RF pre-distortion technology ensure that the system can acquire the maximum CTB, CSO, and SBS targets in the case of excellent performance CNR .

     Flexibility: it can independently transmit 1~2 ways of satellite signals. An extra way of CATV signal is optional.

     Reliability: The 19 "1U standard rack, built-in high-performance dual switching power supply, it can work in the backup at 85 ∽ 265Vac City Network Voltage, MS-level automatic switching; chassis cooling automatic temperature control.

     Intuitive: The machine is equipped with microprocessor monitors the working state of the laser, the panel LCD window displays the operating parameters.

     Network type: Select All-piece status monitoring transponder guarantee to meet the national standard and be compatible with the SCTE HMS standard, it enable network management monitoring capabilities.

     Hot plug-in type:Aluminum structured plug switching power supply allows for heat dissipation and replacement. Dual power supply both hot and cold backup.
