Black GFS1550F-E CATV Optical Transmitter / 1550nm Optical Transmitter
● Both the external modulator and laser are imported from the
United States orJapan.
● 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.
