EXFO Optical Wave Expert – DWDM Channel Checker and OTDR

EXFO Optical Wave Expert – DWDM Channel Checker and OTDR

The EXFO Optical Wave Expert is a handheld tester that combines DWDM channel power validation with OTDR capabilities on a single port. This device is an industry-first channel checker with integrated tunable DWDM OTDR capabilities on a single port, making it an easy-to-use and compact handheld tester that eliminates the need for multiple instruments. Integrating channel checker and OTDR capabilities on a single port means less unnecessary manipulation of the optical fiber and improved field efficiency. This translates into faster mean-time-to-repair (MTTR), making the trial and error approach obsolete.

Features

The EXFO Optical Wave Expert integrates channel power validation and reflectometry characterization on a single port. This means that technicians can automatically identify faulty channels and follow through with fault location by leveraging intelligent OTDR capabilities. The EXFO Optical Wave Expert is available in MaxTester and FTBx format and has a compact and portable form factor. The EXFO Optical Wave Expert is iOLM-ready, meaning it can perform multiple one-touch acquisitions with clear MUX/DEMUX characterization. The device is also equipped with C-BAND ITU-T G.692 grid channels (12-62), a bar graph, and a table view on a wide touch-screen display. The device allows for in-channel testing of active networks.

Benefits

Integrating channel checker and OTDR capabilities on a single port means less unnecessary manipulation of the optical fiber and improved field efficiency. This translates into faster mean-time-to-repair (MTTR), making the trial-and-error approach obsolete. The device has an intuitive graphical interface that makes it easy to use, even for unfamiliar technicians. The device is also rugged and compact, making it ideal for field use.

Applications

The EXFO Optical Wave Expert is ideal for use in fiber optic networks, where it can be used to troubleshoot DWDM networks. The device is also useful for general testing and troubleshooting optical fiber networks. The device is handy for technicians who must identify faulty channels and follow through with fault location by leveraging intelligent OTDR capabilities.
