40-Channel 100GHz Thermal AWG Mux/Demux
1. Product Description
This document presents the generic specification for the 40-channel 100GHz AWG (Arrayed waveguide gratings)
MUX/DEMUX component supplied for use in DWDM system.
40 channel AWG MUX/DEMUX
This component is designed for use within the C -band release of DWDM system. To decrease the power
dissipation of the devices in different environmental conditions, the AWG package is special designed with
selection of reliable thermal plastic with low thermal conduction, and the AWG operating temperature is
controlled by using foil resist heater or Peltier TEC with thermistor temperature sensor. Different input and output
fibers, such as SM fibers, MM fibers and PM fiber can be selected to meet different applications. The component
is designed for minimum roll-off over the ±100pm clear bandwidth whilst not exceeding the maximum insertion
loss of 6.0dB.
Issue V0 released to reflect standard 100GHz AWG specifications, and can be modified according to customer
requirement.

6. Reliability Specifications
The planar DWDM components described within this datasheet are currently under development. Whilst the design, material selection
and manufacturing processes have been chosen for high reliability the devices have not been submitted to an extensive reliability
assurance program. It is Modultech’s aim to qualify these planar DWDM devices to the Telcordia reliability assurance practices and
requirements for fiber optic and opto-electronic components (GR-1221-CORE, Generic Reliability Assurance Requirements for Fiber
Optic Branching Components, and Telcordia TR-NWT-000468, Reliability Assurance Practices for Opto-electronic Devices in Interoffice
Applications).
