Abstract

A fully connectorized optic fiber tap assembly is described that includes a first upstream connector interface configured to receive a downstream connector of a first upstream optic fiber line, and a first downstream connector interface configured to receive an upstream connector of a first downstream optic fiber line. The tap assembly further includes a set of service drop line connector interfaces. Moreover, an optic fiber tap of the assembly is configured to: receive an optical signal from the upstream connector interface, extract a portion of the optical signal, direct the extracted portion of the optical signal to the set of service drop line connector interfaces, and pass a remaining portion of the optical signal to the downstream connector interface. The fully connectorized optic fiber tap assembly is configured to be connected to the first upstream optic fiber line and the first downstream optic fiber line without splicing.
