850nm Window Multi-mode Single
Channel Integrated Tap Monitors
ITMSMM Series
Product Description
Oplink’s Multi-mode Single Channel Integrated Tap 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.
