The connectors include respective ferrules, an end of a single-mode optical fiber and a collimator lens is mounted in each ferrule, and the collimator lens is disposed at the tip of the single-mode optical fiber. The optical fiber connection mechanism is configured so that when the ferrules are inserted into ends of the split sleeve, the collimator lenses face each other with a gap therebetween and the single-mode optical fibers are optically connected to each other. The ferrules are loosely fit in the corresponding connectors to be displaceable within a predetermined range in the direction along the optical axis of the single-mode optical fibers.

A telecommunication enclosure includes an environmentally sealed housing having an interior volume. The sealed enclosure includes a housing wall defining an opening that extends from the interior to an exterior of the enclosure, the housing wall defining interior threads within the opening. A port-defining element mounts within the opening, the port-defining element defining exterior threads that are threadingly mated with respect to the interior threads to retain the port-defining element within the opening. The port-defining element defines a connector port for receiving a hardened fiber optic connector.

The present disclosure relates to a ruggedized/hardened fiber optic connection system designed to reduce cost. In one example, selected features of a fiber optic adapter are integrated with a wall (24) of an enclosure (22). The adapter comprises a sleeve port (26) into which an optical adapter subassembly is inserted. The subassembly comprises a sleeve part (44) which is inserted into the sleeve, a ferrule alignment sleeve (48) which is inserted into the sleeve part, a ferrule (55) with hub which is inserted into the alignment sleeve, and fixing clip (46) securing the ferrule with hub into the alignment sleeve and the sleeve part.

An optical fiber connector of a networking module faceplate assembly includes a shuttle body, a connection assembly, and a retention clip. The shuttle body including a fiber slot extending across the shuttle body and adapted for an optical fiber to extend therethrough. The connection assembly is adapted to connect the optical fiber of the networking module to an external optical fiber connector. The connection assembly includes a ferrule flange fiber termination, a split sleeve, and a ferrule. The ferrule flange fiber termination positioned within the shuttle body and adapted to splice to an end of the optical fiber. A length of the optical fiber connector can be less than half a length of the external optical fiber connector.

A GH splitter includes a splitter body including an upper end cover and a lower end cover fastened therewith, a fastening member and a connecting part are correspondingly provided at two sides of the upper and the lower end covers, a positioning hole and a positioning block are correspondingly provided at two ends of the upper and the lower end covers, a clustering tube and a branching tube are respectively provided at a front end and a rear end inside the splitter body, a sealing ring is provided at a front end of the clustering tube, annular protrusions are provided on both sides of the branching tube, the upper and the lower end covers are provided with joint grooves at positions corresponding to the clustering tube and the branching tube. It has convenience in installment and maintenance, firmness in internal structure, not causing the deviation of branch switching.

A fiber optic receptacle includes a receptable housing defining an internal cavity opening through an internal end and an opposing external end; an alignment assembly disposed within the internal cavity defined by the receptacle housing and received through the internal end, the alignment assembly comprising a plurality of alignment supports and an alignment sleeve having ends contained with each alignment support; and a retainer for retaining the alignment assembly within the internal cavity defined by the receptacle housing, the retainer having an opening and a plurality of tangs disposed about the opening.

A ferrule-based fiber optic connectors having a ferrule retraction balancing characteristic for preserving optical performance are disclosed. The fiber optic connector comprises a connector assembly, a connector sleeve assembly and a balancing resilient member. The connector assembly comprises a ferrule and a resilient member for biasing the ferrule forward and the connector sleeve assembly comprises a housing and a ferrule sleeve, where the connector assembly is at least partially disposed in the passageway of the housing and the ferrule of the connector assembly is at least partially disposed in the ferrule sleeve. The balancing resilient member biases the housing to a forward position with the biasing resilient member having a predetermined resilient force that is greater than the friction force required for displacement of the ferrule within the ferrule sleeve.

A two-piece fiber optic connector and a corresponding two-piece adapter allow for the tripling of the optical fibers that can be used with a standard fiber-optic cassette. The two-piece fiber optic connector has a fold-over latch to engage the adapter. The two-piece adapter has at least one latch to engage the standard fiber-optic cassette to retain the two-piece adapter and the fiber optic connectors in the adapter within the cassette. This allows for the retrofitting and/or continued use of the standard fiber-optic cassette.

An optical cable includes a single optical connector configured for insertion into an optical receptacle so as to receive optical signals at a plurality of different wavelengths from the optical receptacle, and multiple electrical connectors, configured for insertion into respective electrical receptacles. The optical cable further includes a plurality of optical fibers, having respective first ends connected together to the single optical connector so as to receive the optical signals. Each of the optical fibers has a respective second end coupled to a respective one of the electrical connectors. Each electrical connector includes a keyed portion to mate with an indentation on a transceiver.
