Network 1550nm Optical Transmitter Externally Modulated 2 Ports Per 10dbm
Description
JUNPU 1550nm Optical Transmitter an economical 1550nm Externally Modulated Optical Transmitter, is produced specially for middle and small CATV station.
Optical transmitter adopts narrow bandwidth (Typ:=1MHz), low noise and continuous wave DFB laser as the light source, adopts CATV special LiNbO3 external modulator to modulate signal, and adopts a series of unique innovation technique to reach the excellent system control. With 47~862MHz bandwidth, CNR 2 53dB, CTB s -65dB, CSO s -65dB, SBS: 13dbmadjustable, Optical transmitter can make CATV network transmit video, audio and data with high perfomance. The machine is equipped with perfect
RS232 communication interface, SNMP network management and 1+1 backup power supply.
1550nm directed modulation optical transmitter max support 20km transmission distance.
If more than 20km, then it should be 1550nm extener modulated optical transmitter.
