Fiber optic cable assemblies having a construction suitable for a first deployment scenario where the optical connection is made to the device externally that may be transformed for a second deployment scenario where the optical connection is disposed within an internal cavity of the device are disclosed. The cable assembly has one or more cable legs disposed within a profile support element and are disposed under the heat shrink. The fiber optic connectors are exposed and suitable for optical connection with the heat shrink intact on the cable assembly and the profile support element further provides further flexibility using different outer housings with the cable assembly when making external optical connections to the device Thus, the concepts disclosed advantageously allow a single cable assembly to support multiple deployment scenarios in the field, thereby reducing complexity.

An optical communication cable bundle is provided. The cable bundle includes a bundle jacket having an inner surface defining a bundle passage and an outer surface defining an exterior surface of the cable bundle, and a plurality of optical fiber subunits located within the bundle passage and surrounded by the bundle jacket, each optical fiber subunit having a subunit jacket defining a subunit passage and a plurality of optical fibers located with the subunit passage. A thickness of the bundle jacket is less than a thickness of each of the subunit jackets and the bundle jacket is extruded tight around the subunit jackets to couple the subunits and the bundle jacket.

A method and system connects multiple cores within one fiber, e.g., a multi-core fiber (MCF), to multiple fibers with single-cores. The single-core fibers can then be terminated by traditional envelopes, such as a single core LC envelope. A connector holds the single-core fibers into a pattern that matches a pattern of all, or a sub group, of the individual cores of the MCF. The single-core fibers may all be terminated to individual connectors to form a fanout or breakout cable. Alternatively, the single-core fibers may extend to another connector wherein the single-core fibers are regrouped into a pattern to mate with the cores of another MCF, hence forming a jumper. One or more of the single core fibers may be terminated along the length of the jumper to form a jumper with one or more tap accesses.

The present disclosure relates to a fiber optic network architecture that uses a factory manufactured break-out cable as a backbone for supporting a chain or chains of indexing optical components that branch outwardly from the factory manufactured break-out cable so as to extend the reach of a fiber optic network.

Disclosed is an optical fiber which includes a core including silica with a core diameter and having at least two dopants, a maximum relative refractive index delta of at least 0.7% and an alpha value in the range of 1.9-2.2. The core has a refractive index profile configured to transmit light in a multimode propagation at a first wavelength .sub.1 in the range of 800-1100 nm and to propagate light in a LP01 mode at a second wavelength .sub.2. The second wavelength .sub.2 is greater than 1200 nm. The optical fiber is structured to have a LP01 mode field diameter in the range of 8.5-12.5 m at 1310 nm.
