The SMA-905 Connector, also know as FSMA Connector, was one of the first fiber optic interconnect system that gained industry wide acceptance. Today the connector is still widely used for military, industrial, and medical applications.
Our SMA-905 Connectors have a threaded coupling nut and feature a stainless steel or a high quality zirconia ferrule with ID sizes up to 1500 microns to accomodate a wide range of optical fibers.
