850 nm Window Multi-mode Single

Channel Integrated Tap Monitors

ITMSMM Series

Oplink’s Multi-mode Single Channel IntegratedTap Monitor (ITMS) is a hybrid component

that integrates a flat spectral response of a thin-film tap with a Si photodiode for power

monitoring applications in 850nm window. The ITMS minimizes component assembly

costs and module footprint while increasing module design efficiency by facilitating fiber

management.

The ITMS 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. Applications include power monitoring, optical network switching/

protection monitoring in GigE networks.

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.
