Bi-directional Integrated TAP

Monitor Arrays

BTMA Series

Product Description

Oplink’s Bi-directional Integrated Tap Monitor Array (BTMA) is assembled using individual Bi-

directional Integrated Tap Monitor (BTMS) to guarantee no optical or electrical cross-talk

among different channels. 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 input or output ports. BTMA minimizes

component assembly costs and module footprint while increasing module design efﬁciency by

facilitating ﬁber management.

Each BTMS in the BTMA integrates the functionality of an optical tap and a photodiode while

delivering low insertion loss and low dark current with high temperature stability over a wide

wavelength range. BTMA is compact and easy to mount on PCB board for module and net-

work system use. Applications include DWDM channel power monitoring, optical network

switching/protection monitoring, re-conﬁgurable optical add/drop multiplexers, and gain/at-

tenuation 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.
