The company said its new FTBx-740C-DWC OTDR offers single-ended troubleshooting of high-value dense wavelength-division multiplexing (DWDM) access links.
EXFO in a statement said that its FTBx-740C-DWC, a tunable OTDR, is 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.
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 locating problems.
In contrast with the traditional light source and OSA approach that requires two technicians and synchronization, this single-ended OTDR test solution enables one technician to quickly respond to network failures.
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 features a high dynamic range for improved performance and the long reach to cover metro/long-haul applications.
