Optical distribution and splice frame including enclosures

An optical distribution and splice frame system includes rack(s), enclosure(s), cable management component(s), and/or cassette(s) that have features to allow for different cable management configurations not yet available in the market. A fiber optic cassette and enclosure are designed to enable flexibility in cable management configurations for the overall system.

Telecommunications module

A telecommunications module defines an interior with separate right and left chambers. An optical component is housed within the left chamber. Signal input and output locations are exposed to the right chamber. The right chamber allows excess fiber to accumulate without bending in a radius smaller than a minimum bend radius. A dual-layered cable management structure is positioned within the right chamber that defines a lower cable-wrapping level and a separate upper cable-wrapping level. The upper cable-wrapping level is defined by a removable cable retainer mounted on a spool defining the lower-cable wrapping level. Cabling carrying the input and output signals are passed between the right and left chambers before and after being processed by the optical component.

BEND INDUCING FIBER ARRAY UNIT

A bend inducing fiber array unit is provided comprising first and second anti-recovery plates and a V-groove chip. Opposing lateral anti-recovery plates are arranged on opposite sides of the first and second anti-recovery plates. Lateral edges on a common side of the anti-recovery plates are secured to a common face of one of the opposing lateral anti-recovery plates to fix the first and second anti-recovery plates relative to each other. A guided portion of the array of optical fibers is positioned in the fiber accommodating grooves of the V-groove chip and the V-groove chip is secured to the second anti-recovery plate such that the fiber accommodating grooves and a fiber guiding face of the first anti-recovery plate are fixed at a relative angle θ approximating the bend in the array of optical fibers.

Rollable optical fiber ribbon with low attenuation, large mode field diameter optical fiber and cable

A rollable optical fiber ribbon utilizing low attenuation, bend insensitive fibers and cables incorporating such rollable ribbons are provided. The optical fibers are supported by a ribbon body, and the ribbon body is formed from a flexible material such that the optical fibers are reversibly movable from an unrolled position to a rolled position. The optical fibers have a large mode filed diameter, such as ≥9 microns at 1310 nm facilitating low attenuation splicing/connectorization. The optical fibers are also highly bend insensitive, such as having a macrobend loss of ≤0.5 dB/turn at 1550 nm for a mandrel diameter of 15 mm.

Optical Fiber Management System

An apparatus forms a module. The apparatus includes a housing configured to load the module through a front end of a panel. The apparatus includes a connector cluster. The apparatus includes a set of tabs corresponding to a set of securing members that secure the module to a panel.

Multi-core fibers are optical fibers each of which has a circular cross section. In each of the multi-core fibers, a plurality of cores are arranged at a prescribed interval, the peripheries thereof are covered by a cladding, and a resin coating is formed on the outer periphery of the cladding. In a cross section of this optical fiber ribbon, said cross section being orthogonal to the length direction, the multi-core fibers are arranged such that the cores of all of the multi-core fibers are all arranged in the same direction. The multi-core fibers are arranged such that central lines of the respective multi-core fibers, said central lines respectively linking three of the cores, all face the thickness direction of the optical fiber ribbon. Furthermore, in the optical fiber ribbon, the arrangement of the cores is substantially constant along the entire length of the optical fiber ribbon in the length direction.

Moveable bend control and patch cord support for telecommunications panel

A termination field and a guide member are independently pivotally coupled to a base body. The termination field pivots relative to the base body along a path of travel. The guide member is coupled to the base body to provide bend radius protection to cables plugged into the termination field. The guide member defines a channel leading the cables from the termination field towards a first side of the base body at an exterior of the base body. In certain examples, the guide member and termination field pivot relative to the base body about different hinge axes. In other examples, the termination field pivots with the guide member for part of the path of travel and relative to the guide member for another part of the path of travel.
