Product Description
EDFA-1550-8H 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,
32 ports outputs, of which the total output power range of 1550nm is
22 to 32dBm. Multiple output power can be matched according to user
demand. Standard model is 15.5dBm per port.

This series product adopts JDSU, Lumentum, Ⅱ-Ⅵ 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.
Delivery is 35 days from order placement

Features
◆ Top quality: Adopt multi-mode high-power pump laser and the
power is optimized through software, which makes the system
achieving excellent CNR.
◆ Reliability: Adopting 19" 1RU standard chassis, built-in high
performance modular switching power supply, can work in
AC90 ～ 265V voltage. DC Dual hot and reserved power supply
with Chassis automatic heat dissipation control.
◆ Intuitive: The built-in microprocessor monitors the working
status of the pump laser, and the working parameters are displayed
on LCD.
◆ 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.
◆ Adjustable output optical power: Advanced design enables a large
adjustable range of output power, and power can be lowered by
0 to -3dBm.
◆ Built-in optical switch option: There are automatic (preferred) or
manual (forced) 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.
