(Part code: FX5000-QU)
Description:

Designed with the installers and operators of enterprise networks in mind, the FiberXpert OTDR 5000 measures, documents and troubleshoots fiber optic networks. The FiberXpert OTDR 5000 provides very high resolution with one of the shortest dead zones available for testing multimode and single-mode fibers, thus enabling measurement of very short fiber links. Automatic analysis simplify the measurement tasks and let you be the fiber expert.

With a high dynamic range and a small event dead zone the FiberXpert OTDR 5000 is the tool for measuring relative short optical fiber links in company networks and data centers. With an event dead zone of less than 80cm it is possible to detect connectors in a short row and measure them highly accurate. To reduce costs and resources the FiberXpert measures using the maximum resolution in the shortest possible time.
