A fiber-optic connector includes a connector body including a housing with a top surface and a bottom surface, the top surface and the bottom surface being joined together by two opposing side surfaces of the housing. The housing has a top slot and a bottom slot thereupon along a longitudinal axis, the top slot and the bottom slot being provided on the top surface and the bottom surface, respectively. A first key structure is slidably positioned within the top slot, and a second key structure is slidably positioned within a bottom.

Reversible polarity MPO fiber optic connector

A multi-fiber, fiber optic connector is provided having a housing having a first end for receiving a multi-fiber fiber optic cable and a second end having openings for the fibers from the cable. First and second keys for setting the polarity of the fibers within the connector located on opposing sides of the connector. The connector has either one of guide pins or guide pin receiving holes for guiding the connection with a second connector. The keys are movable between a first active position and a second retracted position, such that when one of the keys is in the first active position, the fibers are presented within the connector in a first polarity and when the second key is in the first active position, the fibers are presented within the connector in a second polarity reversed from the first polarity.

In a mateable pair of MPO connectors, a first connector has a first key structure and a second key structure, each of which is moveable between a first position and a second position thereof. When the first key structure is in the first position, the second key structure is in the second position and vice versa. The second connector similarly has a first key structure and a second key structure, each moveable between a first position and a second position thereof, and when the first key structure is in the first position, the second key structure is in the second position and vice versa. A polarity of at least one of the first connector and the second connector is reversible without disassembly thereof.

The present arrangement provides a twisted pair of conductors, each with a profiled insulation thereon, where in the twisted pair, the peak to peak contact of adjacent conductor insulation is ensured along the length of the pair. To this end, each of the profiled insulations on the conductors of the pair are forward twisted prior to twinning to ensure the maximum number of peak to peak contacts per unit length of the pair.

Forward twisted profiled insulation for LAN cables

The present arrangement provides a communication cable having a plurality of twisted pair communication elements, a jacket surrounding the twisted pairs and a shield element disposed between the pairs and the jacket. The shield element is constructed as a tape substrate with a plurality of foil shielding elements disposed thereon, the foil shielding elements being formed in the shape of triangles and arranged on the substrate with at least a first foil shield element having a base of its triangle shape disposed substantially parallel to a longitudinal edge of the tape substrate. Each subsequent triangle is disposed on the tape substrate at a distance apart from the first triangle foil shielding element with a base of its triangle shape disposed substantially parallel to an opposite longitudinal edge of the tape substrate.

Discontinuous shielding tapes for data communications cable

A fiber optic connector has an opening for receiving a fiber optic cable, a pair of locating pins positioned adjacent to a front end ferrule and a housing for providing a covering between the opening and the locating pins. The locating pins are configured to be moveable between a first forward position where the locating pins extend out of the front ferrule and the housing and a second retracted position where the locating pins are retracted within the front ferrule and the housing. The locating pins are moveable from the first forward position and the second retracted position by a user via a mechanism accessible outside of the housing and without opening the housing.

Fiber optic connector

A cable is provided containing one or more polymeric elements for reduction of crosstalk. The cable includes a plurality of unshielded twisted pairs, each of which is an insulated conductor pair twisted around one another, each having a different lay length. A jacket encloses the plurality of unshielded twisted pairs, where an unshielded twisted pair, has the longest lay length among the plurality of unshielded twisted pairs is positioned within the center of the jacket such that an axis of the twisted pairs that has the longest lay length substantially coincides with the central longitudinal axis of the cable. A plurality of bumper elements are disposed within the jacket in the interstices between said plurality of unshielded twisted pairs, where the bumper elements are profiled polymer structures.

Profile filler tubes in LAN cables

A device for making a profiled insulation having an extrusion die with an extrusion tip and a polymer chamber surrounding the extrusion tip. The polymer chamber has at least one air chamber therein. The air chamber is held in place and coupled to the outside of the extrusion die by a vertical fin extending outwards from the extrusion tip. When molten polymer flows through the polymer chamber around the air chamber, an opening is introduced into the polymer such that the profiled insulation is formed as the polymer exits the extrusion die, having a longitudinal cavity therein corresponding to the location of the opening formed by the at least one air chamber.

Profiled insulation LAN cables

A wire has a conductor and an insulation extruded onto the conductor. The insulation has a plurality of alternating crests and crevasses, where the ratio of the distance from the conductor to a top of the crest to the distance from the conductor to a lowest point in the adjacent crevasse is at least 1.1 and where the ratio is sustained within a tolerance variation of not more than 15% along the length of the wire.
