SPARTANBURG, S.C., June 12, 2012 — The Noyes Test and Inspection Div. of AFL has introduced a series of bend-insensitive fiber rings. A “must have” for fiber optic cable installers, fiber rings are combined with an optical time-domain reflectometer (OTDR) to enable connector-to-connector testing of fibers and identification of breaks, splices and macrobends. The new models include FR1-BIF-150 (150-m ring), FR1-BIF-500 (500-m ring) and FR1-BIF-1000 (1-km ring). Each is available with any combination of connectors, including UPC and APC SC, ST, FC and LC.
The bend-insensitive fiber rings allow network personnel to use launch and receive cables that match the fiber in the network under test.
OTDRs require launch and receive cables to accurately measure the insertion loss and reflectance of the near- and/or far-end connections of a fiber optic link. Depending on the application and the length of fiber being tested, the cables can range from 150 to 1000 m. Noyes fiber rings are an alternative to a 150-m patch cable or a 1000-m box of fiber.
AFL offers fiber rings in a wide variety of types to meet industry requirements, including G.652-compliant single-, multimode 62.5-μm, multimode 50-μm (OM2, OM3 and OM4) and G.657A2-compliant bend-insensitive fiber. Standard lengths are 150, 500 and 1000 m, and all common connector styles are available. Custom fiber types, lengths and connector styles are available upon request.
