Product Overview: Anritsu FiberConnect Bare Fiber Adaptor

Performs optical measurements without terminating the fiber or optical component under test

The FiberConnect Bare Fiber Adapter is the ultimate time-saving solution for coupling unterminated fiber or optical components to test equipment. By allowing the user to perform optical measurements without cleaving or terminating, which requires additional equipment and procedures, the overall test time can be reduced by 50 percent. The low loss and highly repeatable connection made using the FiberConnect is similar to that of connectorized fibers or components.

The FiberConnect contains a precision glass ferrule that is permanently aligned to a connectorized cable assembly. Available in multiple configurations, the FiberConnect is suited for a variety of multimode or single-mode applications. It is offered with UPC or APC polish in an assortment of connector styles. For added convenience, the FiberConnect can be attached to a smooth surface with either the integrated magnetic mount or the supplied suction-cup base.

The FiberConnect is extremely easy-to-use; only a single drop of index matching oil is required. The fiber to be coupled is stripped and cleaned, then inserted into the unit until the end face meets the permanently mounted fiber. The result is a low loss, low-reflectance connection suitable for any testing application.
