  • Patent number: 12085764
    Abstract: A connection system for a printed circuit board employs either an inline or transverse board-mounted connector for holding board-mounted optical fibers. A plug-in connector can blind mate with the board-mounted connector. The plug-in connector has a plug-in connector body, a plug-in ferrule, and a plug-in ferrule holder. The plug-in holder latches with the plug-in connector body at either of two positions to selectively configure the plug-in connector for blind mating with either the inline or transverse board-mounted connector. The board-mounted fibers can be supported by a board-mounted ferrule assembly including a ferrule and a ferrule holder that is configured to selectively attach the board-mounted ferrule assembly to either of an inline board-mounted connector body and a transverse board-mounted connector body.

  • Publication number: 20240280761
    Abstract: A fiber optic adapter includes an adapter housing defining a connector port for mating with a fiber optic connector in either of two connector polarity orientations. A polarity cap is releasably securable to the adapter housing in either of two adapter polarity orientations, each of which only permits insertion of the connector in one respective connector polarity orientation. The changing polarity of the adapter is facilitated by removing the polarity cap from the adapter housing, inverting the polarity cap, and reinstalling the inverted polarity cap.

  • Patent number: 12066672
    Abstract: Fiber optic network systems are implemented, at least in part, using very small form factor (VSFF) interconnect components such as VSFF duplex connector; VSFF mechanical transfer ferrule (MT) connector; VSFF duplex uniboot connector; VSFF MT uniboot connector; VSFF duplex adapter; VSFF MT adapter; VSFF duplex pluggable transceiver; VSFF MT pluggable transceiver; VSFF patch cable assembly; VSFF trunk cable; and/or VSFF breakout cable. The VSFF fiber optic network systems can define fiber breakout cabling that connects large trunk cables to many peripheral network locations. The network systems can define branches and sub-branches from a trunk cable. The network systems can define cross-connect sub-networks between sets of transceivers or adapters. The network systems can define a trunk-to-transceiver cabling assembly for connecting a trunk cable to at least 32 transceiver ports.

  • Patent number: 11982845
    Abstract: In an ingress-protected fiber optic connector assembly, an optical fiber plug mates with a receptacle at a bulkhead adapter and an ingress-protected housing assembly couples to the bulkhead adapter to enclose the optical fiber plug. The ingress-protected housing includes an outer housing and a compressible cable seal. The outer housing is rotatable to advance the outer housing, simultaneously compressing the compressible cable seal and fastening the housing assembly to the bulkhead adapter. The outer housing can have a plurality coupling positions at which the cable seal is compressed with a different amount of compression force. A non-sealing cable clamp can transfer tension on the cable to the bulkhead adapter.

  • Patent number: 11934020
    Abstract: An optoelectronic module and optoelectronic connector assemblies can be used for releasable connection of a laser source to the module from a location exterior to the module. The construction of the optoelectronic connector assemblies is such that both in connection and disconnection, the electrical contacts are broken before the optical contacts so that the laser may power down before the optical connection is broken. The optoelectronic connection assemblies have blind mating features. Some versions are free of any latching or mechanical interconnection of the optoelectronic connector assemblies to each other. A spring has a construction which permits it to be received onto a cable by lateral movement of the spring.
