Integrated TAP Monitor Arrays
ITMA Series
Product Description
Oplink’s Integrated TAP Monitor Array (ITMA) is a compact, multi-channel power-
monitoring device. It increases module design flexibility and efficiency by significantly
reducing the number of assembly components and facilitating fiber management.
ITMA integrates the functionality of an optical coupler and a photodiode while deliv-
ering low insertion loss and low dark current with high temperature stability over a
wide operating wavelength range.
Easily mounted on a PCB, Oplink’s standard 12/14-pin package provides power moni-
toring for up to ten 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 func-
tion module or subsystem.
