Unidirectional Integrated TAP

Monitor Array

UTMA Series

Product Description

Oplink’s Unidirectional Integrated Tap Monitor Array (UTMA) is assembled using

individual Unidirectional Integrated Tap Monitor (UTMS) to guarantee no optical

or electrical cross-talk among different channels. UTMS is a hybrid component

that integrates a ﬂat spectral response of a thin-ﬁlm tap with a high sensitivity PIN

photodiode for power monitoring applications.The Unidirectional feature allows

power monitoring from input port only. UTMA minimizes component assembly

costs and module footprint while increasing module design efﬁciency by facilitating

ﬁber management.

Each UTMS in the UTMA integrates the functionality of an optical coupler and a

photodiode while delivering low insertion loss and low dark current with high tem-

perature stability over a wide wavelength range. It is compact and easy to mount

on a PCB board for module and network system use.Applications include DWDM

channel power monitoring, optical network switching/protection monitoring, re-

conﬁgurable optical add/drop multiplexers, and gain/attenuation monitoring in am-

pliﬁer 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.
