VGM4500-FM06
Variable Gain EDFA Module (without
MSA)
C-Band DWDM VGA Module without MSA
Description
a. Idealphotonics
VGM4500-FM06 series is a next generation variable gain optical amplifier
module, which with the most excellent performance and most completes functions
in the market. It adopts nowadays most excellent optical performance, most
advanced electronic technology and most complete software functions. Remarkable transient suppression control
technology and heat management control technology let many complicated optical
functions achieved. It is the most versatile multifunction optical amplifier in
the market.
b. This next generation variable gain amplifier module is composed with two
stages amplifier: variable gain pre-amplifier (PA) and variable gain booster
amplifier (BA). The gain of these two stages amplifier can be independently set
in a certain range. There is a connector between the two stages amplifier,
which used for mid-stage access, such as optical Add-Drop module (OADM), dispersion
compensation module (DCM) and others optical modules.
c. VGM4500-FM06 adopts 130×212×19.5mm (including heat sinks) ultra-thin
appearance; signal unit +5VDC power supply, low consumption.
d. VGM4500-FM06 is a device
without Mid-stage Access, which according with various communication technology
requirements of C-Band 44 or 88 channels DWDM system, widely used in long
distance and ultra-long distance transmission network. Since its complete
functions, it can be used as line amplifier, pre-amplifier, booster amplifier.
Applications
• Long-distance or ultra-long haul network between the city
• Line amplifier, Pre-amplifier, Booster, Add/Drop amplifier
Features
