Integrated WDM Monitor Arrays
Oplink's Integrated WDM Monitor Array(IWMA) is a compact, multi-channel WDM
power-monitoring 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 and 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 moni-
toring for up to eight channels. Applications include DWDM channel power monitor-
ing, 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.
