Single Channel Integrated WDM
Monitors
IWMS Series
Product Description
Oplink’s single channel Integrated WDM Monitor (IWMS) is a compact, WDM power-moni-
toring device. It allows power monitoring at one or more wavelengths while transmitting
all other wavelengths.
The IWMS integrates the functionality of a WDM filter and a photodiode while delivering
low insertion loss and low dark current with high temperature stability over a wide wave-
length range. It increases module design flexibility and efficiency by facilitating fiber man-
agement. It is compact and easy to mount on a PCB board for module and system use. Ap-
plications include DWDM channel power monitoring, optical network switching/protection
monitoring, re-configurable optical add/drop multiplexers, and gain/attenuation monitor-
ing 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.
