A optical cable member includes an optical cable, a fixing member, a first housing tube, and a second housing tube. The optical cable includes an optical fiber and a tensile strength member. In the optical cable, a cable main body housing the optical fiber and the tensile strength member, and a cable exposure portion in which the optical fiber and the tensile strength member are exposed to an outside are provided. The fixing member fixes the tensile strength member. The first housing tube is disposed between the fixing member and the cable main body, houses the tensile strength member therein, and allows the optical fiber to extend therein. The second housing tube is disposed on a side opposite to the first housing tube of the fixing member, and houses the optical fiber of the cable exposure portion therein. The second housing tube is a bendable member.

In particular, the plurality of tubes (104) is arranged in an innermost layer (108) and an outermost layer (110). Additionally, young's modulus of the innermost layer (108) is greater than young's modulus of the outermost layer (110). Further, the diameter of the central strength member (102) is in a range of 1.5 millimetres to 6 millimetres.

A butt closure base includes a base housing extending along a longitudinal axis between a first outer surface and a second outer surface, the base housing defining a plurality of cavities between the first and second outer surfaces, the plurality of cavities aligned in an annular array. A first gel is disposed in each of the plurality of cavities. The butt closure base further includes a plurality of wedge assemblies, each of the plurality of wedge assemblies removably insertable into one of the plurality of cavities. Each of the plurality of wedge assemblies includes an outer cover, a second gel, and a main pressure plate in contact with the second gel. The main pressure plate is movable along the longitudinal axis to apply pressure to the second gel.

A method for the continuous production of a thin-walled, perforated metal hollow profile with one or more fibre waveguides mounted therein. The method includes supplying of a flat metal strip at a first supply rate to a deforming device, which continuously deforms the metal strip into a metal hollow profile with a slot running in a longitudinal direction. Two opposite edges of the metal strip deformed into the metal hollow profile that lie flush against one another in a contact region extending in the longitudinal direction of the metal hollow profile are continuously welded to one another, drawn off from the welding region and perforated. The method further includes positioning a protective tube reaching into the welded metal hollow profile on the draw-off side to beyond the perforation point and supplying one or more fibre waveguides from one or more fibre unwinders via the protective tube, such that the fibre waveguide or waveguides are introduced into the perforated metal hollow profile from the guide or protective tube downstream of the perforation point in the drawing-off direction. The perforated metal hollow profile with the fibre waveguide or fibre waveguides mounted therein is received in a receiving unit.

A machining method for an optical fiber unit, includes: preparing an optical fiber unit in which a first optical fiber ribbon that intermittently connects a first plurality of optical fibers and a second optical fiber ribbon that intermittently connects a second plurality of optical fibers are layered and arranged, the first optical fiber ribbon and the second optical fiber ribbon are intermittently connected in a length direction by interlayer connection parts; opening up a separation part between the first optical fiber ribbon and the second optical fiber ribbon; and breaking the interlayer connection parts by inserting a finger or a division tool into the opened separation part.

A passive optical network includes a central office providing subscriber signals; a drop terminal; and a wave division multiplexer. A fiber distribution hub may split or separate out dedicated optical signals from subscriber optical signals between the central office and the drop terminal. The wave division multiplexer separates dedicated optical signals pertaining to a specific dedicated subscriber from other optical signals on the line received at the wave division multiplexer. The wave division multiplexer may be part of a cable or part of an intermediate service terminal.

A fiber distribution hub comprises a housing, a first side panel and a second side panel comprising one or more ports, and at least one cover disposed between the first side panel and the second side panel and forming an interior compartment. The interior compartment may include cable managers. A mounting structure aerially strand mounts the fiber distribution hub. Fiber distribution hubs comprising a first fiber distribution hub, a second fiber distribution hub configured to couple to the first fiber distribution hub, and a mounting structure configured to aerially strand mount the fiber distribution hub are also disclosed.

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.
