  • Patent number: 9625660
    Abstract: The present disclosure relates to a fiber optic connector assembly having a fiber optic connector including a main connector body and a rear insert secured within a rear cable termination end of the main connector body. The fiber optic connector assembly has a fiber optic cable that includes an optical fiber, a strength layer and an outer jacket. The optical fiber has a ferrule-less end portion accessible at a front mating end of the main connector body. A first shape recoverable sleeve secures the optical fiber to a substrate anchored to the rear insert. An axial gap exists between the forward end of the outer jacket and the rearward end of the rear insert. A second shape recoverable sleeve secures the outer jacket to the rear insert. An adhesive material at least partially fills the axial gap.

  • Patent number: 9360636
    Abstract: An improved, reversibly terminable fiber stub connector assembly is provided that can be readily and positively terminated in the field using simple termination tools. This allows repositioning or replacement of fiber optic cable field fibers if termination is not acceptable in performance. The tool may be a hand-held tool, or used in conjunction with a connector support structure to provide simplified and expeditious field termination of fiber optic cables. The cam tool can include a throughbore that enables connection of a patchcord to the stub fiber of the connector during or shortly after termination without removal of the termination tool. Accordingly, field testing of the connection can be made at the site of termination.

The connector (20) comprises a housing (6), a port (48) within the housing for receiving an end (35) of an optical fiber (38), a cylindrical ferrule (32) within the housing (6) having opposite first and second ends (33, 35), and an optical fiber stub held axially (14) within the ferrule (32) and extending between said ferrule ends (33, 35). The connector (20) also has a lens (8) for projecting and/or receiving an expanded beam (40) optically coupled with the optical fiber stub at the first ferrule end (33). A sleeve (34) surrounds the ferrule (32) and extends towards the port (48) axially away from the second ferrule end (35) to present an open end to the sleeve for receiving a termination ferrule (36) of an optical fiber (38) inserted into the port.

  • Patent number: 8550727
    Abstract: Methods and apparatuses are provided for performing electromagnetic interference (EMI) containment in a parallel optical communications system. The apparatus includes a curved surface formed in the system housing near the opening through which a stack of ribbon cables passes, and a spring device. The stack of ribbon cables is sandwiched in between the curved surface of the housing and the spring device. The spring device exerts a force on the stack of ribbon cables that presses the stack against the curved surface of the housing and forms a sharp bend in the stack just before the stack passes through the opening in the housing. Because EMI radiation is restricted to propagation along the sharply bent pathway of the stack of ribbon cables, most or all of the EMI radiation traveling along that pathway is either attenuated or reflected before it reaches the opening.

  • Patent number: 8491199
    Abstract: A fiber optic socket contact includes a socket contact body and a capped sleeve containing a spring and a retention clip that engages a socket contact body. A fiber optic pin contact includes a pin contact body. One optical fiber is gripped by the socket contact body and another optical fiber is gripped by the pin contact body. When connector housings holding the fiber optic socket contact and the fiber optic pin contact are connected together, the fiber optic pin contact enters the capped sleeve which aligns the fiber optic pin contact with the fiber optic socket contact. The spring applies a force to keep the optical fibers pressed together. In preferred arrangements the fiber optic socket contact and the fiber optic pin contact have outer dimensions that substantially match outer dimensions specified for electrical socket and pin contacts.

  • Publication number: 20120328249
    Abstract: The disclosure is directed to cable assemblies having at least one fiber optic connector and methods for making the same. In particular, fiber optic cable assemblies having a crimp band disposed about a cushioning member on a fiber optic cable along with methods for making the same are disclosed. The cable assemblies including the cushioning member are advantageous since they provide a load distribution of the crimp band about the fiber optic cable which may preserve optical performance and/or enable the use of fiber optic cables having smaller diameters. Additionally, the fiber optic cables of the cable assemblies may be sub-units of a larger cable.
