EXFO OTDR to expedite troubleshooting of metro Ethernet links

EXFO Inc. (NASDAQ: EXFO, TSX: EXF) has announced the release of its FTBx-740C-DWC, a high-resolution tunable OTDR designed to test through field mux/demux channels using the customer´s wavelength in order to efficiently troubleshoot faulty links or deliver first-time-right deployments during construction, the company said.

This DWDM OTDR complements EXFO´s coarse wavelength-division multiplexing (CWDM) OTDR and Ethernet test modules to provide a comprehensive and powerful kit for field technicians.

With commercial services in fiber-to-the-building (FTTB)/fiber-to-the-premises (FTTP) and cellular‑backhaul (CBH) deployments evolving and migrating from CWDM to DWDM, EXFO´s tunable DWDM OTDR empowers technicians to perform in-service tests from the head-end right up to the customer´s premise while easily locating problems and preventing costly SLA penalties and maintenance downtime periods.

EXFO´s FTBx-740C-DWC unit is a tunable OTDR in the C-band, and covers channel spacing of 100 GHz/50 GHz based on the ITU-T standard grid. The tunable laser also features a high dynamic range for improved performance and the long reach needed to cover metro/long-haul applications. In addition, this new product features advanced, EXFO-best OTDR technology that contributed to EXFO´s win of the 2015 Frost & Sullivan Fiber-Optic Test Equipment Market Share Leadership Award.
