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.

Abstract: The present invention relates to the pluggable connection of an optoelectronic module with an optoelectronic connector assembly from a location exterior to the optoelectronic connector assembly. An optoelectronic module comprises a housing having a proximate end and a rear end in a longitudinal direction; a ferrule arranged adjacent to the proximate end of the housing; an electrical contact arranged adjacent to the proximate end of the housing and stacked with the ferrule in a vertical direction; a biasing members configured to bias the ferrule in the longitudinal direction once pressed; and a guiding member extending in the longitudinal direction and configured to guide the optoelectronic module connected to another optoelectronic module. The optoelectronic connection between the optoelectronic module and the optoelectronic connector assembly has blind mating features.

Abstract: An optical signal device for connecting to a receptacle of an optical motherboard includes an optical module and an optical connector coupled to the optical module. The optical connector attaches to the receptacle of the optical motherboard to optically connect the optical module to the optical motherboard. The optical connector has a first optical interface axis and a second optical interface axis different from the first optical interface axis. The optical connector is configured to convey optical signals to and/or from the optical motherboard along at least one of the first or second optical interface axes.

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.

Abstract: A passive optical alignment coupling between two bodies each having a complementary interstitial two-dimensional planar array of protrusions defining an array of interstices. Each array of protrusions defines an array of discrete protrusions separated and isolated from one another on the surface of the corresponding bodies. When the bodies are pressed together, the array of protrusions defined on one body intermesh with protrusions defined on the other body with protrusions of one body received in corresponding interstices defined on the other body. The protrusion surfaces of each adjacent pair of protrusions are in point contact. The first body is removably attachable to the second body to define a demountable coupling, with the first array of alignment features against the second array of alignment features to define an elastic averaging coupling, thereby passively aligning the first body to the second body.

Abstract: A fiber optic connection assembly includes a cage and an adapter assembly releasably securable in the cage. The adapter assembly includes an insert cartridge and an adapter in the insert cartridge. The adapter maters with fiber optic connectors. The insert cartridge has at least one actuator for selectively releasing the adapter assembly from the cage. The adapter assembly is bi-directionally loadable into and extractable from the cage. The fiber optic connection assembly is usable to install a fiber optic trunk cable by plugging a trunk cable connector into the adapter before inserting the adapter assembly into the cage. The adapter assembly can also be extracted from the cage while one or more connectors remain mated with the adapter.

Abstract: An optical connector cleaning tool includes a fitting portion (44) fitted in the first or second hole (36, 37) of a connection component (32) into which a compact dual core optical connector is fitted on one end side and a cleaning medium (45) projecting from the fitting portion (44). The fitting portion (44) is formed to have a shape by which the fitting portion (44) is fitted in the first or second hole (36, 37) in each of the first and second postures as postures shifted through 180° with respect to as the center the middle (P2) of a virtual straight line connecting the centers of the two ferrules when viewed from an axial direction of the compact dual core optical connector. The fitting portion (44) contacts one ferrule in a state in which the fitting portion (44) is set in the first posture. The fitting portion (44) contacts the other ferrule in a state in which the fitting portion (44) is set in the second posture. There can be provided an optical connector cleaning tool by which the connection end faces of the compact dual core optical connector having two ferrules in one housing can be cleaned.

Abstract: A new fiber optic connector provides a very small form factor with reduced size. The fiber optic connector may comprise a single-body housing having a front end and rear end in a longitudinal direction, two ferrules accommodated in the housing and protruding from the front end of the housing, a back housing positioned adjacent to the rear end of the housing, two springs positioned between the two ferrules and the back housing to urge the two ferrules to move forward, and a boot assembly connected to the rear end of the housing. The housing comprises a latch arm extending obliquely upwards, and the latch arm is in a depressed state when the fiber optic connector is mating with an adapter.

Abstract: A demountable connection of an optical connector using a foundation having features for integrated optical coupling and demountable coupling. The foundation provides for demountable passive alignment connection to an optical connector. The foundation is permanently attached and aligned to a PIC chip. The foundation includes optical elements that redirect and reshape incident light to follow a desired light beam shape and path between the optical connector and the optoelectronic device. The foundation may include a combination of different optical elements having optical properties that produces the desired light beam quality and direction. The foundation also includes passive alignment features that matches the passive alignment features on the facing side of the optical connector. The foundation has a unitary, monolithic body that is provided with the optical elements and the passive alignment features.
