1 m RJ11 6P4C to RJ45 8P8C adapter cable

This 1 metre white cable converts an RJ45 Ethernet socket to an RJ11 6P4C plug so a landline telephone, fax machine or analogue modem can connect to a DSL splitter or POTS line. It is intended for home or small-office users who need to bridge modern Ethernet cabling and legacy voice devices. The cable is new and weighs .704 ounces.

RJ11 6P4C plug and RJ45 8P8C plug

The 6P4C end carries the four active conductors required for standard analogue voice or DSL signals while the 8P8C end fits the Ethernet-style wall panel or router port. This pin arrangement lets the existing telephone or fax hardware operate without rewiring the premises. The RJ45 plug cannot be inserted into an RJ11 wall jack.

6P4C wiring on the telephone side

Only the four centre contacts of the RJ11 plug are populated, matching the typical analogue device requirement. Builders who need all eight conductors for data networking or PoE cannot use this cable for that purpose.

Questions about this item

Will the RJ11 6P4C plug or RJ45 8P8C connector wear out first with daily plugging?

Both connectors are standard telephone-grade plugs; the RJ11 6P4C side sees the same insertion cycles as the RJ45 8P8C end, so neither is rated for a different lifespan.

What signal degradation appears first on a 1m run carrying DSL over this cable?

The 1m length keeps attenuation well within ADSL splitter tolerances; the limiting factor is the RJ45 8P8C-to-RJ11 6P4C wiring map, not cable distance.

Does the white jacket add noticeable heat or power draw when the line stays active all day?

The cord is passive copper with no electronics, so it draws zero power and generates no measurable heat during continuous DSL or voice use.
