Overview

The Monoprice 100935 is a 50-foot RJ11 telephone patch cable designed to replace shorter cables when you need to reach a wall jack that's farther away from your phone, fax machine, or DSL modem. It uses a straight-wired configuration, meaning the pin assignments are preserved from one end to the other—this is the standard wiring type for connecting telephone devices to wall outlets. The cable features 4 conductors, supporting both single-line and two-line telephone service through its RJ11 (6P4C) connectors.

The flat, ribbon-style cable body with a silver satin finish is a practical design choice for telephone cables that need to be routed discreetly. It tucks neatly under carpet edges, runs along baseboards with minimal visibility, and passes through narrow gaps that would be difficult for round cables. At 50 feet, it provides enough length to span most rooms or connect between adjacent rooms without requiring couplers or extension adapters. For homes or offices that still rely on landline phones, fax machines, or DSL connections, this cable provides a straightforward, affordable way to extend your reach to a distant jack.
