FWA-1550H-16xN Series, 16 ports CATV EDFAProduct Description
FWA-1550H series erbium and ytterbium co-doped high-power fiber
amplifier is the latest optical transmission system for CATV FTTH.
The optical input number: 1 port of CATV or 2 redundant CATV
inputs, 16 ports outputs, of which the total output power range of
1550nm is 27 ~ 37dBm. Multiple output power can be matched
according to user demand.This series product adopts JDSU, Lumentum,
etc multimode high power pump laser as pump source and American OFS
closed beam splitter as double-cladding synthesizer. Built-in
optical power output stabilization circuit and laser thermoelectric
cooler temperature stabilization control circuit ensure the best
performance of the EDFA and the long-term stable operation of the
laser. The microprocessor software monitors the working status of
the laser, and the working parameters are displayed on the digital
panel (LCD). Once the laser's working parameters deviate from the
allowable range set by the software, the micro-processing will
automatically turn off the laser power, and the red light flashes
to alert. Product feature1. Top quality: Adopt multi-mode
high-power pump laser and the power is optimized through software,
which makes the system achieving excellent CNR.2. Reliability:
Adopt 19" 2U standard chassis, built-in high performance modular
switching power supply, can work in AC165 ~ 265V city network
voltage. DC 48V hot-swappable power supply option is available as
well. Dual hot and reserved power supply with Chassis automatic
heat dissipation control.3. Intuitive: The built-in microprocessor
monitors the working status of the pump laser, and the working
parameters are displayed on LCD.4. Network management Interface:
Web transponder is line with the national standard and compatible
with the SCTE HMS standard, achieving WEB monitoring function. The
red warning symbol is displayed on the web page, which is
convenient for troubleshooting.5. Adjustable output optical power:
Advanced design enables a large adjustable range of output power,
and power can be lowered by 0 ~ -3dBm.6. Built-in optical switch
option: There are automatic (prefer) or manual (force) switch mode
when CATV signal has main path A and redundant path B optical
switch input (OPT SWTTCH). Automatic mode uses the main path A by
default, it switches to redundant path B if A input power fails.
