1550nmExternal Modulation Optical Transmitter
1550nm FTTx External Modulation Optical Transmitter(Build-in EDFA)

1550nm FTTx External Modulation Optical TransmitterBuild-in EDFA


 

Features

1. Built-in EDFA makes 1550nm external modulation optical transmitter to gave 13 ~24dBm output. Single, dual or more outs for the user’s choice.

2. The transmitter adopts original DFB laser as signal source and LiNbO3 modulator, the EDFA part adopts OFS fiber and pump laser of JDSU and Fitel.

3. Perfect pre-distortion circuit ensures the best CTB and CSO when the CNR is in high standard.

4.Perfect SBS suppress circuit and adjustable SBS in 13,16, 19suitable for different types of CATV network.

5.AGC and MGC control.

6. 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.

7. The transmitter provides RJ45 and RS232 standard interface for the connecting the computer and monitoring.
