944 Series FC Connectors Amphenols 944 Series fiber optic FC connectors effectively terminate optical fiber in a variety of network applications. The connectors are secured using a threaded coupling nut, providing a significant increase in pull-out performance. The FC connectors also feature an internal cavity and epoxy injection tube that virtually eliminates the possibility of improper epoxy application, thus providing higher manufacturing yields. Every aspect of the connector system is precision manufactured to produce reliable and consistent performance. The 944 series is available in tunable or non-tunable PC versions for flexibility in specific performance requirements. The FC/APC connector system features a tight-fit keyway that prohibits the possible mis-mating between FC/PC and FC/APC connectors.
