Bare Fiber Adaptor, Single-mode, ST Connector

The F-AS-ST Bare Fiber Adaptor enables quick and easy temporary ST connections of single-mode fibers. This adaptor is very useful for connecting fibers to power meters. Optical time-domain reflectometers (OTDRs), and a variety of other instruments, enabling in-situ functional testing without having to attach a permanent connector.
The bare fiber is secured in place with a special precision cut foam pad to ensure kink free, diffusion free operation and repeatable measurements. Fibers with buffer sizes of up to 900 μm can be accommodated. Piano wires for cleaning blocked ferrules are included with all adaptors.
Single-mode and Multimode Adapter Kits
Also available are kits that contain a single adapter body, FC, SC and ST interchangeable connector tips, a universal mating sleeve for quick ferrule-to-ferrule connections and a fiber stop to ensure that bare cleaved fibers are flush with the front of the connector ferrule. Piano wires for cleaning blocked ferrules are also included with all adapters.
