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.

A connection arrangement is provided for connecting an armored cable to a connection piece. The arrangement has a ferrule for fitting onto the end of the armored cable, that has an abutment flange, a washer and a threaded region. The threaded region has at least a portion threaded according to a first thread standard. A lock nut is configured to fit over the armored cable, and to connect with a nut thread on the connection piece. The lock nut and the connection piece are configured to compress the ferrule therebetween forming a watertight connection. An armor of the armored cable has a least a portion of the armor threaded to match the first thread standard.

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.

An adapter ferrule is provided configured to connect between a connector and an armored cable. The connector has a connection piece, a nut thread, a lock nut, and a ferrule, the ferrule having at least a threaded region of a first thread standard. The armored cable has a second thread standard different from the first thread standard. The adapter ferrule has a small block and a large block. The small block has an internal threading matching the second thread standard of the armor, the outer dimension of which fits within the threaded region of the ferrule. The large block has a recessed thread configured to fit over the outside of the threaded region of the ferrule, the recessed thread having the same thread standard as the threaded region of the ferrule.

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.

A lighting system is provided with a plurality of light fixtures within a room and at least one control system for controlling the plurality of light fixtures within a room. At least one of the light fixtures among the plurality of light fixtures within the room includes a patch panel thereon. The control system is attached to the patch panel on a first side of the patch panel, and a remaining of the plurality of light fixtures in the room are connected to the patch panel on a second side.

A power sourcing equipment for remote powering of PoE equipment is provided including a transceiver for receiving an optical signal, a power module for receiving a power input, and a PoE device for receiving and converting the optical signal and the power input and controlling at least one remote device. A surge protector slot with a removable and field replaceable surge protector unit is provided. The removable field replaceable surge protector unit, after triggering by a surge event, is removable and replaceable with a new field replaceable surge protector unit allowing for continued surge protection without replacing the entire power sourcing equipment.

A multi-mode optical fiber includes a glass center for conducting fundamental and high order modes of light waves, the high order modes including a first desired group of high order modes and a second undesired group of high order modes. A cladding surrounds the glass center, the glass center and cladding forming a core. A trench within the cladding surrounding the glass center reflects the first and second groups of high order modes into the core. The multi-mode optical fiber is constructed with a pressure applying element thereover that applies continuous pressure to the core, along the length of the multi-mode optical fiber, such that the at least the first group of desired high order modes are permitted to be transmitted through the core and where the second group of undesired high order modes are suppressed.

A cable, cable component and reel arrangement includes a cable, at least one component, such as a cable component, configured to be employed in connection with the cable, and a reel, on which the cable is arranged, the reel having a barrel opening. The barrel opening includes a plurality of brackets, the brackets are arranged at spaced locations within the barrel opening and configured to support at least one component for storage and shipment.

A multi-fiber, fiber optic connector has a housing having a first end for receiving a multi-fiber fiber optic cable and a second end having openings for said fibers from said cable. First and second key slots are provided for accepting a removable key for setting the polarity of the fibers within the connector, with the first and second key slots located on opposing sides of the connector. The connector has guide pins or guide pin receiving holes for guiding the connection with a second connector. The removable key is movable between the first and second key slots, the key slot with the removable key corresponding to a first active slot and the key slot without the removable key corresponding to a non-active slot. When the removable key is in the first key slot, it results in the first key slot being active with the fibers being presented within the connector in a first polarity. When the removable key is moved from the first key slot to the second key slot, activating the second key slot and deactivating the first key slot, the fibers are presented within the connector in a second polarity, reversed from the first polarity.

A LAN cable is provided having a plurality of twisted pairs, a jacket surrounding the twisted pair and at least one discontinuous shield tape having a plurality of separated metal segments. The discontinuous shielding tape is folded and arranged between the plurality of twisted pairs, separating each of said plurality of pairs from one another.

A multi-mode optical fiber includes a glass center for conducting fundamental and high order modes of light waves, the high order modes including a first desired group of high order modes and a second undesired group of high order modes. A cladding surrounds the glass center, the glass center and cladding forming a core. A trench within the cladding surrounds the glass center reflecting the first and second groups of high order modes into the core. An acrylic layer surrounds the core. A buffer coating of polymer surrounds the acrylic layer and the core. The buffer coating is a pressure extruded polymer, where the buffer coating retains at least some of the pressure from the pressure extrusion and applies continuous pressure to the acrylic layer and the core therein, along the length of the fiber, such that the at least the first group of desired high order modes are permitted to be transmitted through the core and where the second group of undesired high order modes are suppressed.
