An optical fiber connector with a housing configured to hold a plurality of optical fiber ferrules is selectively reconfigurable between a first configuration and a second configuration different from the first configuration. The housing can have different widths in the first and second configurations. The ferrules can have different ferrule arrangements in the first and second configurations. The optical fiber connector can be mateable with different types of receptacles in the first and second configurations. Reconfiguration can be achieved by disconnecting a rear housing from a plurality of front housings at first set of attachment points, rotating the rear housing 180° in relation to the front housings, and attaching the rear housing to the front housings at the second set of attachment points.

Fiber optic connectors and connectorized fiber optic cables include connector housings having locking portions defined on the connector housing that allow the connector housing to be selectively coupled to a corresponding push-button securing member of a multiport assembly. Methods for selectively connecting a fiber optic connector to and disconnecting the fiber optic connector from the multiport assemblies allow for connector housings to be forcibly and nondestructively removed from the multiport assembly.

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.

Fiber optic connectors, connector housings, connectorized cable assemblies, and methods for the connectorization of cable assemblies are provided with particular cable adapter features, adapter extensions, multi-diametrical sealing flexures, subcutaneous sealing elements, and combinations thereof, for improved connector and cable performance, integrity, and durability.

An optical fiber including a core region having an outer radius r.sub.1 in a range from 4.0 μm to 8.0 μm and a relative refractive index profile Δ.sub.1 with a maximum relative refractive index Δ.sub.1max in a range from 0.20% to 0.50%, a cladding region comprising a trench cladding region having a minimum relative refractive index Δ.sub.3min greater than −0.60% and less than −0.10%, and a trench volume greater than 30%-μm.sup.2 and an outer cladding region having a relative refractive index Δ.sub.4 in a range from −0.10% to 0.10%. The optical fiber also including a primary coating and a secondary coating. The optical fiber has a mode field diameter at 1310 nm of greater than 8.8 microns, a cable cutoff wavelength of less than 1260 nm, a zero dispersion wavelength between 1300 nm and 1324 nm, and low macrobend loss at 1550 nm.

Fiber optic connectors, cable assemblies and methods for making the same are disclosed. In one embodiment, the optical connector comprises a housing and a ferrule. The housing comprises a longitudinal passageway between a rear end and a front end, and, a part of the rear portion of the housing comprises a round cross-section and a part of the front portion of the housing comprises a non-round cross-section with a transition region disposed between the rear portion and the front portion.

Multiports having connection ports with associated securing features and methods for making the same are disclosed. In one embodiment comprises a multiport for providing an optical connection comprising a shell, a connection port insert, and at least one securing feature. The shell comprises a first end having a first opening leading to a cavity. The connection port insert comprises a body having a front face and at least one connection port comprising an optical connector opening extending from the front face into the connection port insert with a connection port passageway extending through part of the connection port insert to a rear portion, where the connection port insert is sized so that at least a portion of the connection port insert fits into the first opening and the cavity of the shell. The at least one securing feature is associated with the at least one connection port.

Multiports comprising a connection port insert having at least one optical port along with methods for making are disclosed. One embodiment is directed to a multiport for providing an optical connection comprising a shell and a connection port insert.
