Product Description
General
The GM series of EDFAs has been specially designed to
provide flexibility by working with a customer’s own drive
and control circuitr y to provide a specific product for use
in metro transmission systems as a booster amplifier.
Optical
This module is based on an erbium-doped fiber amplifier
(EDFA), which is pumped with 980 nm diode lasers.
Input and output ports are optically isolated to maintain
stable operation of the amplifier. An optical splitter on
the output port taps a small amount of light onto photo-
diodes to enable optical power monitoring.
Electrical
The GM series of EDFA products is equipped with a stan-
dard 16-pin male DIP connector.
Package
The units are housed within ver y small modules with
input and output connections through single-mode fiber
pigtails and are fitted as standard with super-polished
FC/UPC or FC/APC connectors. Other types of connec-
tors are available on request.

Safety Information and Handling Precautions
EDFAs are class III laser products. Please read carefully the following safety information prior to handling and installing.
The signal output of the pump laser and EDFA is invisible, yet it can be of high power level
and therefore can cause damage to the eyes or skin. Please do not look at the fiber cross
section directly without protection devices.
There are precision optical devices inside the EDFA; therefore extreme care should be taken
not to impose excess vibration or shaking. Care should also be taken in handling the pigtail
fibers since they are easily broken.
There are static sensitive devices inside the EDFA, please make sure proper grounding
and electrical power connection.
Do not attempt to open the EDFA by any unauthorized personnel. Please contact Nanovation
technical support for assistance.
