Erbium-Doped Fiber Amplifier (EDFA) - GW Series
Nanovation’s GW series of EDFAs is a cost-efficient solution for dense wavelength
division multiplexing (DWDM) applications where high per formance and reliability are
critical. They are available in Booster, Inline and Preamplifier configurations to cover a
wide range of applications in the full C-Band. The GW series of products is supplied
without internal electronics for those systems that use external electronics to moni-
tor and control the EDFA.
Features
•Excellent gain flatness over the full C-Band
•High saturated output power
•Low noise figure
•Input and output optical isolation and power monitoring
•TTL compatible alarm and warning capability
•Wide operating temperature and humidity ranges
•Compact packaging
•Bellcore GR-1312-CORE qualified and ISO 9001 cer tified
Applications
•High per formance Full C-Band DWDM systems
•Booster, inline or preamplifier configurations
Product Description
General
The GW series of EDFA products has been specially
designed to provide flexibility by working with a customer’s
own drive and control circuitry to provide a specific product
for use in DWDM transmission systems as a booster,
inline, or preamplifier.
Optical
The amplifiers have been optimized for full C-Band DWDM
operations by careful selection of both passive and active
components. All amplifiers are pumped with high reliability
pumps, and all are provided with optical monitor outputs to
allow customer spectral analysis or monitoring of the ampli-
fied signal. An optical output monitor port is a customer
option that can assist the user in such analysis or monitoring.
Electrical
Electrical connection is through a standard DB25
male 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 connectors 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.
