Unidirectional Integrated TAP

Monitor Array

UTMA Series

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

tional IntegratedTap 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 de-

livering low insertion loss and low dark current with high temperature stability over a wide wavelength

range. It is compact and easy to mount on a PCB board for module and network system use.Applica-

tions 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.
