BTMS S0003

Bi-directional Single Channel
Integrated Tap Monitors
BTMS Series
Product Description
Oplink’s Single Channel Bi-directional Integrated Tap Monitor (BTMS) 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 Bi-directional feature allows power monitoring from
both input and output ports. BTMS minimizes component assembly costs and module footprint while increasing module design efficiency by facilitating fiber management.
The BTMS 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 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.
