80ch 50G Athermal AWG(80ch 50G AAWG)
Model
: 50AAWG
This document presents the generic
specification for the 80-channel
50GHz Athermal AWG MUX/DEMUX Rackmount supplied for use in DWDM system.
Athermal AWG(AAWG) have equivalent performance to
standard Thermal AWG(TAWG) but require no electrical power for stabilization.
They can be used as direct replacements for Thin Film Filters(Filter type DWDM
module) for cases where no power is available, also suitable for outdoor
applications over -30 to +70 degree in access networks. Flyin’s Athermal AWG(AAWG) provide excellent optical
performance, high reliability, ease of fiber handling and power saving solution
in a compact package. Different input and output fibers, such as SM fibers, MM
fibers and PM fiber can be selected to meet different applications. We can just
offer 19” 1U rackmount package for 50G AWG products.
The planar DWDM components(Thermal/Athermal AWG) from Flyin Optronics are
fully qualified according to Telcordia reliability assurance requirements for
fiber optic and opto-electronic components (GR-1221-CORE/UNC, Generic
Reliability Assurance Requirements for Fiber Optic Branching Components, and
Telcordia TR-NWT-000468, Reliability Assurance Practices for Opto-electronic
Devices).
