Adaptive Fiber Test Heads OTU-8000 Optical Test Unit

The Adaptive Fiber Test Head lies at the core of the VIAVI optical network monitoring system (ONMSi). Combining optical time-domain reflectometry (OTDR) and optical-switch technology, a single OTU-8000 unit can test thousands of fiber links. When a fiber fault occurs, the ONMSi reports the GPS location of the fault within minutes. This adaptive racked Fiber Test Head is great for Access PON or DAA networks as well as metro rings, data center interconnects, and long haul networks utilizing xWDM wavelength plans.

The modularity of the OTU-8000 meets all of the requirements for monitoring light or dark fiber-optic networks. Integrated with the latest technology, it can monitor both long-haul and FTTx networks. With the OTU-8000 installed at the central office, providers can test hundreds of live passive optical networks (PONs), regardless of the split ratio. It can accelerate PON installations when setting up new customers and troubleshooting by enabling technicians to sectionalize the network to determine the cause of a fault. Organizations concerned with network security issues can use the OTU-8000 to detect and locate fiber tapping after only a few tenths of a decibel are inserted.
