Multi-fiber, fiber optic cable assemblies may be configured so that the terminal ends of the cables have pre-assembled back-post assemblies that include pre-assembled ferrules, such as MPO ferrules that meet the requisite tolerances needed for fiber optic transmissions. To protect the pre-assembled components from damage prior to and during installation, pre-assembled components may be enclosed within a protective housing. The housing with pre-assembled components may be of a size smaller than fully assembled connectors so as to be sized to fit through a conduit. The remaining connector housing components for the multi-fiber connectors may be provided separately and may be configured to be attached to the back-post assembly after installation of the cable.

A 4.3/10 coaxial connector configured to receive a mating 4.3/10 connector includes: an inner contact; a dielectric spacer: and an outer contact, the dielectric spacer separating the inner contact and the outer contact. The outer contact includes an outer wall and a plurality of spring fingers, the spring fingers configured to deflect radially inwardly when the mating 4.3/10 connector is mated. The connector further comprises blocking structure that prevents mating of a Mini-Din connector.

A roadway access hole drill for cutting a square or rectangular access hole in a roadway having a first saw opposing a second saw and a third saw opposing a fourth saw. A method of cutting a microtrench in which the buried utility is exposed by opening a square or rectangular access hole in a roadway above the buried utility using the roadway access hole drill that is controlled by a computer system connected to an under-roadway detection unit that detects a buried utility and stops movement of the drill to avoid damaging the buried utility.

In one aspect of the disclosure a communications network or topology is presented that includes one or more modular or adaptable smart pole assemblies. Each smart pole assembly can include a pole structure supporting a data-communications module and having a hollow interior through which a connectorized vertical cabling structure extends. Jumper cables can be provided to connect components associated with the data-communications module with the vertical cabling structure such that no cabling or wiring has to be removed or installed from the pole hollow interior when components are added, removed, or replaced. The vertical cabling structure or harness can include one or more of connectorized fiber optic cables, DC power cables, and connectorized Category 6 cables. In one example, the fiber optic cables are terminated with hardened multi-fiber optical connectors at each end.

Provided are (i) a fiber-optic cable having a cable sheath that enables significant changes in the cable's cross-sectional shape when the cable is bent and (ii) a raceway that can be used to deploy such a fiber-optic cable.

Various embodiments include methods and apparatus structured to install an optical fiber cable into a well at a well site. In a from-bottom-to-top embodiment, an anchor deployed at a selected location in a hole of the well can be used and the optical fiber cable can be pulled up to a surface of the well from the selected location. In a from-top-to-bottom embodiment, an optical fiber cable can be moved down from the surface until an end of the optical fiber cable is locked at a selected location by a catcher disposed at the selected location. With the optical fiber cable in the well, a portion of the optical fiber cable can be coupled to surface instrumentation. Additional apparatus, systems, and methods can be implemented in a variety of applications.
