Features
Integrated WDM Monitor Arrays
Standard,12-pin Package
Oplink's Integrated WDM Monitor Array(IWMA) is a compact, multi-channel WDM
Easily Mounted on a PCB
power-monitoring device. It allows power monitoring at one set of wavelengths while
4 or 8 Channel
Configurations
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.
Wide Operating Wavelength
Range
Low Insertion Loss and PDL
Low Dark Current
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.
High Temperature Stability
Applications
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.
