Integrated TAP Monitor Arrays
ITMA Series

Product Description

Oplink’s Integrated TAP Monitor Array (ITMA) is a compact, multi-channel powermonitoring 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 delivering 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 monitoring for up to ten 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.
