A telecommunications closure includes a plurality of connector ports, and a plurality of dust caps for the connector ports wherein a lanyard connects one of the dust caps with one of the ports. The dust caps are mateable and demateable with each of the ports. The closure with the dust caps in place are sealed for outdoor use. All of the port bodies of the ports have the same general color. All of the dust caps have the same general color as the port bodies. The lanyards may have different colors from the port bodies and different colors from the dust cap. Some lanyards can match the color of the port bodies and/or the dust cap bodies. At least two lanyards may have different colors from each other. One or more identification areas can be provided on the lanyard for labeling, printing or marking indicia on the identification areas.

A passively aligned fan-out apparatus for a multicore fiber (MCF) includes a fan-out assembly that comprises a fan-out substrate, small-clad fibers (SCFs) supported in SCF V-grooves of the fan-out substrate, and alignment rods disposed outboard alignment V-grooves of the fan-out substrate. The SCFs have a distal-end pitch P2D at a distal end of the fan-out substrate greater than the proximal-end pitch P2P of the SCFs at a proximal end of the fan-out substrate. An MCF assembly and/or single mode fiber (SMF) assembly may also be provided as part of the fan-out apparatus.

A fiber optic distribution terminal includes a cable spool rotatably disposed within an enclosure; an optical power splitter and a termination region carried by the cable spool; an optical cable deployable from the enclosure by rotating the cable spool by pulling on a connectorized end of the optical cable; and splitter pigtails extending between the optical power splitter and the termination region. One fiber of the optical cable extending between the connectorized end and the splitter input. The other fibers of the optical cable extend to a multi-fiber adapter.

An indexing terminal arrangement includes a terminal housing that receives an input cable; an optical power splitter disposed within the interior of the terminal housing; a first multi-fiber optical adapter coupled to the terminal housing; a first single-fiber optical adapter coupled to the terminal housing; and a pass-through multi-fiber optical adapter coupled to the terminal housing. Split optical signals are provided to the first multi-fiber optical adapter and the first single-fiber optical adapter. Unsplit and indexed optical signals are provided to the pass-through optical adapter.

A fiber node connector includes a first duct fitting and a second duct fitting. The first duct fitting is configured to be fixedly coupled with a flexible duct, to couple a nut with the flexible duct, to permit the nut to rotate relative to the flexible duct, and to permit limited relative axial movement between the nut and the flexible duct. The second duct fitting is configured to be axially and rotatably fixed to the flexible duct, to couple a connector body to the flexible duct, to permit the connector body to rotate relative to the flexible duct, and to permit limited relative axial movement between the connector body and the flexible duct.

A fiber optic cassette includes a body defining a front and an opposite rear. A cable entry location, such as a multi-fiber connector, is defined on the body for a cable to enter the cassette, wherein a plurality of optical fibers from the cable extend into the cassette and form terminations at one or more single or multi-fiber connectors adjacent the front of the body. A flexible substrate is positioned between the cable entry location and the connectors adjacent the front of the body, the flexible substrate rigidly supporting the plurality of optical fibers. Each of the connectors adjacent the front of the body includes a ferrule. Dark fibers can be provided if not all fiber locations are used in the multi-fiber connectors. Multiple flexible substrates can be used with one or more multi-fiber connectors.

The present disclosure relates to a distribution cable assembly that has various features to enable flexible configurations to accommodate various data center configurations.

A fiber optic fanout assembly includes: a fiber optic trunk cable comprising a plurality of optical fibers within a surrounding jacket; a fanout housing with an internal bore and rear and front end portions, the fanout housing receiving the optical fibers from the trunk cable within the internal bore though the rear end portion; a plurality of furcation tubes, each containing one or more of the optical fibers; a first sealing structure that creates a first seal between the fanout housing and the jacket of the fiber optic cable; a first disk having a plurality of holes, the first disk mounted to the front end portion of the fanout housing, wherein the furcation tubes and optical fibers residing therein are inserted into the holes in the first disk; and a plurality of second sealing structures, each of which provides a second seal between the furcation tubes and the first disk.

Fiber optic connectors, cable assemblies and methods for making the same are disclosed. In one embodiment, the optical connector comprises a housing and a multifiber ferrule. The housing comprises a longitudinal passageway between a rear end and a front end, and a rear portion of the housing comprises a keying portion and at least one locking feature integrally formed in the rear portion of the housing.

A fiber fanout assembly is provided with one or more endcaps, an epoxy fill hole, and air vent holes. A mold can be used with endcaps to create an epoxy body without an external housing structure. External housing structures can also be provided with one or more endcaps. Air vent holes can be provided in the endcaps. An epoxy fill hole can be provided in an endcap. An epoxy fill hole can also be provided adjacent to a fiber breakout end of the fiber fanout housing.
