Vszerda RJ45 8P4C to RJ11 6P4C adapter 20cm

SKU CH-0TWR-K9VK3

Converts an RJ45 Ethernet plug to an RJ11 telephone socket on a 20 cm lead

  • Connect Ethernet cables to telephone sockets via RJ45 male to RJ11 female interface
  • Compact 20 cm length suits tight desk or wall installations
  • White plastic housing matches common cable colours for tidy appearance
  • 2 x 1.5 x 2.3 cm body fits alongside other connectors without blocking ports
  • Single adapter included for immediate plug-and-play telephone or modem linking

Adapter purpose

This Vszerda adapter converts an RJ45 8P4C male plug into an RJ11 6P4C female socket. It lets you connect a standard telephone handset or analogue modem to an Ethernet-style wall port or patch cable. The 20 cm length keeps the link tidy on a desk or in a cabinet.

Capacity and headroom

The moulded plastic body measures 2 x 1.5 x 2.3 cm and carries four active contacts from the RJ45 side to the RJ11 side. It passes voice-grade analogue signals and low-speed data such as fax or dial-up without amplification. Bandwidth beyond plain-old-telephone frequencies is not supported.

Upgrade context

The adapter replaces a bulky inline coupler or a custom-wired patch cord when you only need a single phone device on an RJ45 drop. It is not for buyers who want to run structured Ethernet data through the same jack or who need multiple telephone lines from one port.

Questions about this item

Will the 8P4C male plug fit the RJ45 wall socket I already have?

Yes, the 8P4C male connector is sized for standard RJ45 sockets, so it will seat in the wall port you are keeping.

How can I confirm the adapter is passing a signal after I plug it in?

Connect a telephone handset to the 6P4C female port; a dial tone or successful call shows the link is active.

What comes in the package and is a separate cable required?

The box contains one white plastic adapter measuring 2 x 1.5 x 2.3 cm; no extra cable is included, so you will need your own RJ11 lead for the phone.
