Junpu Overlay Catv Satellite Fiber Optical Transmitter 45 ~ 2600Mhz
Description:
- Optical Transmitter adopts high-linearity butterfly DFB laser which
is directly modulated to transmit 47-862MHz and 960~2600MHz
signal in a single fiber.
- Optical Transmitter can choose ITU standard wavelength for DWDM
system to extend and update the networks. It can be amplified
by EDFA and EYDFA for huge FTTH system. It can be compatible with
any FTTx PON technology to realize the combination of CATV,DVB-S ,
Internetm and FTTH.
- Optical Transmitter adopts 19” standard rack, the parameters of the
machine is controlled by micro-processor, and the status and fault
alarm are displayed by the LCD in the front panel. Standard RJ 45
supports snmp management. The built-in laser APC, ATC control
circuit assures the mlong life of the laser and reliable work.
Product Feature:
- Adopt low noise imported DFB laser.
- Superior pre-distortion circuit design, in achieving high standards
of CNR value, there are still perfect CTB and CSO performance
value.
- Intelligent fan, it began to run when the chassis temperature
reaches the set 32 ~ 35 ℃.
- AGC control, so that different RF input level can still maintain a
considerable output performance.
- VFD or LED display, with laser monitoring, digital display, fault
alarm, network management and other functions; once the laser
operating parameters deviate from the software set the allowable
range, will alert.
- With standard RS232 interface for local network management and
monitoring of computers.
- With standard RJ45 interface support SNMP for remote monitoring.
- High-quality switching power supply, can be 90V ~ 265V AC or -48V
DC work.
- Single input with frequency 47~2600MHz.
- CATV and SAT-IF signal can be transmitted in a single fiber
- It can be amplified by EDFA and EYDFA, compatible with any FTTX PON
technology
