TFT 1550D Externally Modulated Optical Transmitter




Features         ● single output or dual output optional. The output optical power ranges from 3dBm to 10dBm.
        ● superior pre-distortion circuit still has the perfect CTB and CSO performance values when the high standard CNR value is reached.
        ● superior SBS suppression circuit, SBS continuous adjustable, can be suitable for different transmission distance network requirements.
        ● AGC control.
        ● Single or dual power supply optional.
        ● The intelligent fan, when the chassis temperature reaches 32 degrees C, it starts to run.
        ● LED display has many functions, such as laser monitoring, digital display, fault alarm, network management and so on. Once the laser's working parameters deviate from the allowable range of software setting, it will alert.
        ● standard RJ45 interface, supports SNMP, remote network management, to adjust AGC, SBS, OMI, and so on.
        ● Through the RS-232 standard interface, users can change the type and specification of the panel display, and can also be used for local network management and monitoring. Technical Specifications
