This Pre-Polished Fiber Optic Connector can save technicans a ton of time in the field. These connectors are so easy to install, you can do it in a minute! There's no hand polishing. No epoxy!Proven mechanical splice technology ensures precise fiber alignment. A factory pre-cleaved, factory-polished ferrule couples to the fiber being terminated with precise mechanical alignment. A proprietary index-matching gel ensures a low loss termination to 50-micron OM3 multimode optical fibers. There are no expensive tools, no messy epoxy needed.A factory-installed wedge clip holds the clamping device open while the fiber is inserted. This clip also enables the use of a Visible Fault Identifier (VFI) to provide a "pass/fail" signal once physical contact is achieved. The connector is compatible with 250-µm and 900-µm optical fibers.This connector is also available in ST and SC versions and for 50-micron and 62.5-micron multimode, as well as single-mode fiber. Connectors for each fiber type are color coded to industry standard requirements to help with identification during and after installation.
