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 footprint
while increasing module design efficiency by facilitating fiber management.
The ITMS 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, 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.
