An optical fiber assembly includes: a component defining at least one inlet for optical fibers, an adapter, an optical fiber cable connected to the adapter, and a push-fit connector. The component includes a through-hole for passage of the optical fibers and an associated mating region to engage the push-fit connector. The optical fiber cable connected to the adapter defines a connection region with a predetermined cross-sectional shape for mating with the push-fit connector. The push-fit connector includes a first end, a second end, and a through-passage extending between the first and second ends. The first end is push-fit connected with the mating region. The second end is push-fit connected to the connection region. Optical fibers from the optical fiber cable can be directed through the push-fit connector and the through-hole. A method of installing optical fibers in a joint housing is also disclosed.
