Single Channel Integrated Tap
Monitors
ITMS Series
Product Description
Oplink’s Single Channel Integrated Tap Monitor (ITMS) 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 ITMS minimizes component assembly costs and module foot-
print while increasing module design efficiency by facilitating fiber management.
The ITMS integrates the functionality of an optical coupler and a photodiode while deliv-
ering 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 net-
work system use. Applications 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.
