In the pitch change part, at least one of the grooves is curved.

Provided is a secure quick communication system disconnect switch box that enables remote verification of communication path connection or disconnection status. The box utilizes a lid having an affixed jumper circuit/assembly bridging or coupling at least two network connections. When the lid to the switch box is attached, the at least two computers/networks are connected via the jumper circuit/assembly. When the lid is removed from the switch box, the jumper circuit/assembly is disconnected from the at least two computer/networks, thereby disconnecting and isolating the otherwise coupled computers/networks. Removal of the lid additionally exposes network maintenance/access ports to provide access to one or more of the computers/network. When the lid is closed, the network maintenance/access ports are inaccessible to the user.

Connectors for a multiport assembly are disclosed. The multiport assembly can include a multiport device that communicatively couples multiple sets or pairs of connectors, such as optical connectors, together. The connectors include securing features to inhibit unintentional withdrawal of the connectors from the multiport device.

A wall box includes an enclosure having a base and a cover connected to the base. The base and the cover enclose an interior region. The wall box further includes a plurality of fiber optic adapters mounted to the enclosure. The fiber optic adapters include an inner port positioned inside the interior region and an outer port positioned at an outer surface of the enclosure. A tray stack is mounted within the interior region. The tray stack includes a tray mount pivotally connected to the enclosure. The tray mount includes a top surface and an oppositely disposed bottom surface. A first splice tray mounting area is disposed on the top surface and a second splice tray mounting area is disposed on the bottom surface. A plurality of trays is disposed in the first splice tray mounting area. A tray is disposed in the second splice tray mounting area.

A fiber optic cassette includes a body defining a front and an opposite rear. A cable entry location 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 non-conventional connectors adjacent the front of the body. A flexible substrate is positioned between the cable entry location and the non-conventional connectors adjacent the front of the body, the flexible substrate rigidly supporting the plurality of optical fibers. Each of the non-conventional connectors adjacent the front of the body includes a ferrule, a ferrule hub supporting the ferrule, and a split sleeve surrounding the ferrule.

An optical fiber distribution element (1810) includes a chassis (1820), an optical device (1900) mounted to the chassis (1820), the optical device (1900) including a plurality of cables (2134) extending from the optical device (1900) into the chassis (1820), and a cable management device (2110/2210) mounted to the chassis (1820). The cable management device (2110/2210) includes a plurality of radius limiters in the form of spools (2132/2232) in a stacked arrangement for managing the cables (2134) extending from the optical device (1900) for further connection within the chassis (1820), wherein a first of the spools (2132/2232) defines a spool wall (2136/2236) having a different wall length than that of a second of the spools (2132/2232), wherein a first of the plurality of cables (2134) is routed around the first of the spools (2132/2232) and a second of the plurality of cables (2134) is routed around the second of the spools (2132/2232) that has a different spool wall length than that of the first of the spools (2132/2232).
