A pushing tool for propelling cable into a duct. The pushing tool includes a drive wheel that is coupled with a base and a rotatable handle. A first cable guide and a second cable guide are configured to hold the cable. A duct guide is configured to hold the duct. Furthermore, a tension wheel is configured to interact with the drive wheel such that an orifice is formed between the tension wheel and the drive wheel, the orifice being configured to receive the cable. Upon rotation of the rotatable handle, the drive wheel interacts with the tension wheel to propel the cable into the duct.

An optical fiber pathway duct comprises a first channel configured to receive a pulling mechanism, and a second channel configured to allow one of a pullable connector and a stub end coupled to an optical fiber cable to pass through the optical pathway duct. The optical fiber pathway duct further comprises a slot disposed between the first channel and the second channel and configured to allow a pulling eye of one of the pullable connector and the stub end coupled to the pulling mechanism to pass through the optical pathway duct.

Certain aspects of the present disclosure provide techniques and corresponding apparatus for making armored cables with one or more optical fibers contained therein. The techniques may be utilized to control an amount of excess fiber length (EFL) in the armored cables. The techniques may also allow introduction of one or more optical fibers directly into a welding process without using an inner tube in the final armored cable. The techniques may also be utilized to reduce friction and static charge on the optical fiber(s) as the fiber(s) are pushed through one or more guide tubes that protect the fiber(s) during the welding process.
