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.
