Product description
FWA****0S EDFA (Erbium Doped Fiber
Amplifier) is a representative one in the optical amplifier. As the
EDFA’s wavelength is ***0nm, it is in line with the low-loss band
of fiber and its technology has been relatively mature, so widely
used. Erbium-doped fiber is the core components of the EDFA, it
makes quartz optical fiber as matrix material, and incorporate a
certain proportion of rare earth element erbium ions (Er3 +) in the
core of a fiber. When certain amount of pump light is injected into
the erbium-doped fiber, Er3 + have been excited from the low-energy
level to the high energy level, due to Er3 + has a very short
lifespan on the high energy level, and soon transit to a higher
level by the form of a non-radiative, and form the population
inversion distribution between this energy level and
low-energy-level. Because the energy between these two energy
levels is exactly equal to the photon energy of ***0nm, stimulated
emission of ***0nm light can only occur, we can only enlarge ***0nm
optical signal.
This series of products adopt **0nm or ***0nm high linearity,
optical isolation, the DFB, thermoelectric cooling DFB laser
produced by JDSU, Fujitsu, Nortel, Lucent, Fitel and other
world-renowned semiconductor companies as the pumping source. In
the interior of the machine is equipped with the light power export
stable circuit and laser Thermoelectric cooling device Temperature
stability control circuit to ensure optimal machine performance and
long-life laser stability. The microprocessor software monitor the
lasers’ working state, the Digital Panel (VFD) displays the
operating parameters. Once the laser operating parameters deviate
from the permissible range set by the software, micro-processing
will automatically turn off laser power, red light goes on to warn,
digital panel prompts cause of troubles., a detailed report of the
device parameters please read "instructions."
Features
â—† High quality:
The former-class pump commonly use **0nm, after-class pump use
***0nm, power is legitimately optimized by software to minimize the
NF of the EDFA, could be comparable with the so-called low-power
optical amplifier. It can make the system to obtain superior
CNR.
â—† Reliability:
Reliability: The *9 "1U standard rack, built-in high-performance
switching power supply,it can work at *5 ∽ **5Vac City Network
Voltage, As well as an optional DC*8V power supply (reservations
required); chassis cooling automatic temperature control.
â—† Intuitive: The
laser is the most expensive machine components, machine equipped
with microprocessor monitors the working state of the laser, the
panel LCD window displays the operating parameters.
â—†Network type:
Select All-piece status monitoring transponder guarantee to meet
the national standard and be compatible with the SCTE HMS standard,
it enable network management monitoring capabilities.
â—† Adjustable
output power: Adjustable output power range(*3dB), The user
specified when ordering.
