50-foot RJ11 extension cord

This 50-foot black telephone extension cord connects telephones, fax machines, modems or answering machines to a standard wall jack. Male RJ11 plugs on both ends carry all four conductors for full compatibility. It extends the reach from an outlet to your device with reliable signal transmission. The cord is new and ready for immediate use.

Replaces short factory cables

It replaces the short line cord supplied with most phones or modems when the wall jack is far from the desk. The 50-foot length covers large rooms, cross-hallway runs or multi-desk setups without couplers. The jump is worth it whenever the original cable cannot reach the outlet. Shorter runs should use a shorter cord to avoid excess slack.

Sustained use on long runs

The four-conductor wiring maintains a stable connection during long calls, fax transmissions or dial-up sessions. Plastic construction resists kinking when routed along baseboards or under carpets. No active electronics means no signal degradation over the full 50-foot distance. The cord handles continuous duty without overheating or noise buildup.

Questions about this item

How much clearance is needed behind a desk for the 6.3 x 2.6 x 0.9 inch connector housing?

The moulded RJ11 plugs measure 6.3 by 2.6 by 0.9 inches, so allow at least that depth plus cable bend radius behind the equipment.

Which wiring scheme do the male RJ11 plugs use, and what happens if I reverse them?

All four conductors run straight through on standard RJ11 pinout; reversing the cord simply swaps line polarity, which most phones tolerate but some modems reject.

When should I replace this 50-foot extension if the plastic jacket turns brittle?

Replace the cord once the white PVC jacket cracks or the .32-ounce connectors feel loose, as degraded insulation can introduce noise on fax or modem lines.
