International Classification:

G02B 6/00

US Classification:

385135, 385134

Abstract:

A splitter module for a fiber distribution hub includes a main body with a first aperture configured to receive an input fiber entering the splitter module, and a second aperture configured for a plurality of distribution fibers exiting the splitter module. The splitter module also includes a fin configured to be received in a slot of a splitter tray of a fiber distribution hub, and a pin configured to engage a hole in the splitter tray. The fin is received in the slot, and the pin is received in the hole of the fiber distribution hub to couple the splitter module to the fiber distribution module.

US Classification:

385147, 385 95, 385103, 385106, 385136

Abstract:

The present disclosure relates to a telecommunications cable including a distribution cable and a tether that branches from the distribution cable at a mid-span breakout location. A flexible closure covers the mid-span breakout location. Within the closure, fibers are broken out from the distribution cable and spliced to fibers of the tether. The lengths of broken out fibers within the flexible closure are provided with sufficient excess fiber length to allow the closure to be readily bent/flexed in any direction without damaging the fibers.

ADC Telecommunications, Inc. - Eden Prairie MN

International Classification:

G02B 6/44

US Classification:

385100, 385115, 385116

Abstract:

A fiber breakout for connecting a branch cable to a fiber optic distribution cable is disclosed. The fiber breakout can include an optical ribbon separated from the distribution cable at a breakout location. An overmold is formed over the optical ribbon and a portion of the distribution cable at the breakout location. An optical fiber breakout connector is also disclosed. The breakout connector has first and second ends, the first end having a multifiber connector for an optical ribbon, and the second end having a plurality of single port connectors. A fiber breakout separates the optical ribbon into a plurality of fibers.

Assignee:

ADC Telecommunications, Inc. - Eden Prairie MN

International Classification:

G02B 6/44

US Classification:

385100, 385135

Abstract:

Certain aspects of the disclosure relate to fiber optic cable systems, packaging configurations and methods that facilitate the effective use and installation of pre-terminated fiber optic cable. A fiber optic cable breakout arrangement can include a main cable, a branch cable that separates from the main cable, and an elongate protective sheath. Fibers of the branch cable can be packaged in the sheath to secure the fibers to the exterior of the main cable. In certain embodiments, the sheath can have a profile height extending generally radially outwardly from the main cable and a width that is greater than the profile height.

International Classification:

G02B 6/44

US Classification:

385100, 385109

Abstract:

A breakout assembly includes a distribution cable, a tether cable, and at least one optical fiber. The distribution cable includes a breakout location having a length.
