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.
