Features
Single Channel Integrated WDM Monitors
Wide Operating Wavelength
Range
Oplink's single channel Integrated WDM Monitor (IWMS) is acompact, WDM power
Low Insertion Loss and PDL
Low Dark Current
monitoring device. It allows power monitoring at one or more wavelengths while transmit-
ting all other wavelengths.
High Temperature Stability
The IWMS integrates the functionality of a WDMfilter and a photodiode while delivering
low insertionloss and low dark current with high temperaturestability over a wide wave-
length range. It increasesmodule design flexibility and efficiency byfacilitating fiber
management. It is compact and easyto mount on a PCB board for module and system
use.Applications include DWDM channel power monitoring,optical network
switching/protection monitoring, re-configurable optical add/dropmultiplexers, and
gain/attenuation monitoring in amplifier systems.
Applications
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.
