Passive Component Modules
For in service fiber monitoring, with ONMSi, OTU-8000, and OTU-5000
Passive components enable testing fibers that are bearing traffic with an OTDR by inserting an out-of-band wavelength (1625 or 1650 nm).
Features
Enables in-service monitoring
Low insertion loss
Wide and flat passband
Exceptional reliability and environmental stability
Compatible with data traffic in band C and L
Install in minutes
Available in various form factors
Applications
Remote fiber test systems
Fiber tapping detection
The OTDR signal is added to the data signal by using a wavelength division multiplexer (WDM). At the other fiber extremity, an optional filter blocks the OTDR signal in case the transmission equipment does not provide a good isolation. When an OTDR measurement range can cover more than one fiber span, a bypass can extend the OTDR signal to the adjacent span to extend the monitoring distance and avoid having to add an additional Optical Test Unit (OTU8000 or OTU5000)
With low insertion loss, a flat passband, exceptional reliability and environmental stability, the modules are well suited for in-service fiber test applications. They install in minutes without tools. They are available in various form factors.
