1550nm optical transmitter with LiNbO3 Extrnal Modulator

SBS: 13~18 continously adjustable

output power is 2 x 7dbm and 2 x 9dbm

long distance fiber optical signal transmission

 

 

1310nm optical transmitter with Imported DFB laser,

output power is 4~31mw, transmission range is within 45km

 

Main Function:

1. JZ 1550nm Series transmitter is a top-class type of high-performance 1550nm external modulation optical transmitter with dual pluggable power supply.  
2. It is designed for the image/video signal transmission of large and medium HFC system. 
3. It is mainly applied to long-distance fiber transmission of TV image signal, digital TV signal, telephone sound signal and data signal.

Function characteristics:

1. Advanced LiNbO3 external modulator and high-performance DFB laser with extremely narrow spectrum line and superb linearity;  optional 2 way optical signal output: FC/APC, SC/APC
2. RF signal predistortion circuit for improving CSO and CTB efficiently; perfect CSO/ CTB( ≥ 65db)index based on good CNR.
3. SBS: Superior SBS restraining design for further transmission distance; adjustable SBS for more flexible configuration;  Restraining SBS (Stimulated Brillouin Scattering) and fiber SPM(Self Phase Modulation) simultaneously for increasing optical power of optical fiber transmission and maintaining linearity degree(13, 16 or 18 dBm) can be adjusted by users; users can change freely for less expedition and risk with 100km long-distance transmission (added optical amplifier) or 65km middle-distance ring net.

4. AGC for different RF input level range to maintain relative output performance, simplifying installation and operating procedure

5. RS485 network management interface, 19″1U standard frame.
