Blue A-40 All-in-One Live Fiber Optic Identifier (OFI) – Single Mode/Multi Mode FTTH Cable Detector (270Hz, 1KHz, 2KHz) $$other

The Blue A-40 identifies live optical fibers by detecting fixed-tone signals at 270Hz, 1KHz and 2KHz, enabling rapid isolation of a specific fiber. Suitable for both Single Mode and Multi Mode links, this OFI lets you quickly locate the required fiber in patch panels and cable bundles. Compact and practical in design, the unit is simple to operate and provides efficient, accurate identification with a low incidence of detection errors.
