Automate fiber network construction test, service activation and assurance monitoring with the best balance between performance and rack mount size

Adaptive Fiber Test Head FTH-7000 for Remote Fiber Test with OTDR module and Internal Switch Options

The Adaptive FTH-7000 combines high resolution optical time-domain reflectometry (OTDR) and optical-switch technology to provide remote test certification of fiber under test during construction or service activation, and continuous assurance through OTDR monitoring of multiple fibers anywhere in the network. A single FTH-7000 can test up to 2304 fibers.  There are many internal and external switch options and the distance tested depends on the OTDR module selected.

The FTH can assure a single critical link or an entire fiber network.

Simplify PON lifecycle management: As part of an ONMSi system, the FTH-7000 accelerates FTTH construction certification, service deployment, and troubleshooting and assurance. It can sectionalize the network to determine the cause of a fault or identify optical budget problems. Trend network health changes over time to monetize valuable links and assure service.

Enhance network security: Detect and locate fiber tapping with extreme precision down to tenths of a decibel of loss.
