Abstract: Optical fibers of a multi-fiber cable are grouped into connection units. The distal ends of the fibers of each connection unit are terminated at a connection unit body that attaches to a tapering cable core formed of longer ones of the connection units. After deployment of the cable, two or more connection units can be stacked together to form a connector or inserted into a connector shell. Prior to deployment of the cable, at least some of the connection units are spaced from each other along the cable. For example, individual connection units may be disposed at one end of the tapering cable core and stacks of connection units may be disposed at the other end of the tapering cable core.

Abstract: A communications panel is configured to hold a plurality of cassettes via tray elements. The cassettes can be pre-mounted to the tray elements before being loaded into the panel. Alternatively, the tray elements can be loaded into the panel prior to installing the cassettes on the tray elements. Some types of tray elements route rear cables (e.g., input cables) of the cassettes to the front of the communications panel. Some types of cassettes route the rear/input cable to the front of the panel. Some types of tray elements (i.e., trays) hold more than one cassette. Other types of tray elements (i.e., cassette managers) hold only one cassette each. Some types of cassette managers define a cable routing path along a common side with the cassettes. Other types of cassette managers define the cable routing path along an opposite side from the cassette.

Abstract: Aspects and techniques of the present disclosure relate to a cable sealing structure comprising a cable sealing body including a gel and methods of making anisotropic behavior in cable sealing structures made with a dry silicone gel. In one aspect, various three-dimensional printing techniques are used to make a cable sealing structure that includes a gel. The cable sealing body has a construction that elastically deforms to apply an elastic spring load to the gel. The cable sealing body has a construction with anisotropic deformation characteristics that allows the cable sealing body to be less deformable in one direction than in others. The cable sealing structure can be utilized to seal fiber optic cables more uniformly while limiting the potential of leakage.

Abstract: A breakaway coupler includes a main body and a secondary body, removably attached to the main body. First and second attachment features are formed on the main and secondary bodies to permit attachment to first and second structures. A breakaway member connects the main and secondary bodies. A guide channel passes through an overlapped portion of the main and secondary bodies and accepts a cable therein. A blade passes across the guide channel to sever the cable when the secondary body is detached from the main body. In operation, a cable clamp frictionally holds the cable. The cable clamp is connected to the breakaway coupler, which is in turn connected to a fixed structure, e.g., a pole. When an excess force is applied to the cable, the main and secondary bodies of the breakaway coupler separate and the blade cuts the cable in the guide channel.
