Unidirectional Single Channel Integrated Tap Monitors UTMS Series Product Description Oplink’s Single Channel Unidirectional Integrated Tap Monitor (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. UTMS minimizes component assembly costs and module footprint while increasing module design efficiency by facilitating fiber management. The UTMS 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 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, reconfigurable 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.
