Product Description
BTMS Series
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 foot-
print 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.
