1 / 2 page S0135 - R02. (web) 20130520 Bi-directional Integrated TAP Monitor Arrays BTMA Series 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.
