OPLINK IWMA

Integrated WDM Monitor Array
IWMA Series
Product Description
Oplink’s Integrated WDM Monitor Array (IWMA) is a compact, multi-channel WDM powermonitoring device. It allows power monitoring at one set of wavelengths while transmitting
another set of wavelengths.
IWMA integrates the functionality of a WDM filter and a photodiode, delivering low insertion loss and low dark current with high temperature stability over a wide wavelength range.
It increases module design flexibility and efficiency by significantly reducing the number of
assembly components and facilitating fiber management.
Easily mounted on a PCB, Oplink’s standard 12-pin package provides power monitoring
for up to eight channels. Applications include DWDM channel power monitoring, optical
network switching/protection monitoring, re-configurable optical add/drop multiplexers, and
gain/attenuation monitoring in amplifier systems.
Oplink can provide customized designs to meet specialized feature applications. Also, Oplink
offers modular assemblies that integrate other components to form a full function module
or subsystem.
