Vszerda

Vszerda RJ45 Female to RJ11 Male Adapter 2 Pack network ethernet cable

SKU CH-9QDW-2557J

Two adapters connect RJ45 Ethernet cables to RJ11 telephone devices with gold-plated contacts

  • Connect analog phones through Ethernet cable
  • RJ45 8P8C female to RJ11 6P4C male connector
  • Gold-plated contacts for reliable signal quality
  • Two adapters included for multiple device connections
  • Designed for telephone, fax, DSL modem and caller ID devices

RJ45-to-RJ11 adapter two-pack

This Vszerda adapter converts an RJ45 8P8C female socket to an RJ11 6P4C male plug. It lets you connect analogue telephones, fax machines, DSL modems or caller-ID units over existing Ethernet cabling without altering the signal. The pack supplies two adapters for multi-device setups. It is not intended for internet routers or other networking equipment.

Gold-plated contacts and passive design

Gold-plated metal contacts provide a reliable electrical path and clear voice quality. The adapter is completely passive, so it draws no power and adds no active components that could generate heat or noise. Installation is a simple plug-in action with no configuration required.

Replaces makeshift wiring for legacy voice gear

This adapter replaces improvised splicing or gender-changer chains when linking RJ11 telephony devices to structured RJ45 runs. The upgrade is worth it when you need a tidy, repeatable connection for analogue phones, fax or DSL gear across Ethernet infrastructure. It does not suit digital data networking or router uplink scenarios.

Questions about this item

How do I plug the RJ11 male end into my telephone line without damaging the pins?

Align the 6P4C male connector with the wall jack and press straight in until it clicks; forcing it at an angle bends the gold-plated contacts.

Will the gold-plated contacts need cleaning or replacement over time?

Gold plating resists oxidation, so the adapter normally lasts the life of the cable without any maintenance.

What is the maximum data rate this adapter can sustain on a dial-up connection?

The 6P4C wiring carries only the two voice pairs, limiting throughput to standard analogue modem speeds.
