Name:1550nm External Optical Transmitter

Model:GFS1550F-E

Feature

●Both the external modulator and laser are imported from theUnited StatesorJapan.
●Perfect pre-distortion circuit ensures the best CTB and CSO when the CNR is in high standard.
●Perfect SBS suppress circuit and adjustable SBS in 13,16, 18,suitablefor different types of CATV net.
●AGC control.
●Internal double power which can be changed automatically.
●Automatically shell temperature control.
●Internal microprocessor software has the function of laser monitoring, parameter display, fault warning, net management and so on. Once the working parameter of the laser goes out of the fixed value of the software, the machine will warn.
●The transmitter provides RJ45 and RS232 standard interface for the connecting the computer and monitoring.
