Pierside Hermaphroditic Fiber Optic Connector

The OCC Pierside family of fiber optic connectors is designed to meet stringent performance characteristics established by the U.S. Navy in accordance with NAVSEA 7379171 and 7379172 drawings. Conceived in 1997, these standards governed the requirements for a durable, high-quality 6- to 12-channel fiber optic hermaphroditic connector system to be concatenated when connecting naval vessels to network interfaces located at docks or piers.

The OCC Pierside style of connector is designed to enable ™genderless™ mating capabilities, without regard for male or female gender configuration of the interfacing connector to which it is mated. The coupling nut of hermaphroditic plug connectors can be selectively adjusted to convert the plug connector to a male or female coupling thread, allowing a hermaphroditic plug to couple to another plug configured in the opposite gender.

This genderless characteristic allows cable assemblies with hermaphroditic plugs on both ends to be deployed without concern for orientation (male or female) when used in a "daisy-chained" configuration. Another benefit of cable assemblies using hermaphroditic plug connectors is that multiple identical cable assemblies can be linked together as needed (limited only by system link budget [dBm]).

This "genderless" characteristic provides extreme flexibility in deployable system architectures and eliminates the gender orientation and logistics of deployment, redeployment or field system reconfiguration. This series of connectors uses MIL-PRF-29504/14 pins and MIL-PRF-29504/15 sockets with a unique captive alignment sleeve in a Detachable Socket Insert (DSI) [wedge-shaped removable insert cap]. Unlike competitive products, OCC plugs are fitted with a tethered hermaphroditic dust cap, and receptacles are fitted with tethered female dust caps.

The OCC Pierside family of fiber optic connectors affords users the most comprehensive complement of connector options available, including replacement dust caps, strain-relief receptacles and 90™ plugs, etc. Available in either single-mode, multimode or a combination of both, the design is compliant to the Commercial Item Description (CID) standard issued by the Naval Sea Command.
