Single Channel Integrated Tap Monitors
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.
