Junpu 2 Ports 1550nm FTTH Catv Optical Transmitter 11dbm In
External Modulation
Description:
- JP15211ET 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 ≥ 53dB, CTB
≤ -65dB, CSO ≤ -65dB, SBS: 13dbmadjustable, Optical transmitter can
make CATV network transmit video, audio and data with high
performance. The machine is equipped with perfect RS232
communication interface, SNMP network management and 1+1 backup
power supply.
- 1550nm externally modulated optical transmitter is the core
equipment in this system. RFTV is a unidirectional analogue and
digital video broadcast. It adopts high efficiency modulation mode
for RF carrier wave and its economy, flexibility and bandwidth
validity is beyond comparison of IPTV. Adopting EPON or P2P access
mode to realize triple-play, FTTx , RFTV broadcasting network in
1550nm optical transmitter wavelength still plays an important
role.
- 1550nm directed modulation optical transmitter max support 20km
transmission distance.
- If more than 20km, then it should be 1550nm extener modulated
optical transmitter.

Product Features:
- Both the external modulator and laser are imported from the United
States or Japan.
- 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 13~19,suitable
for 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.
