Product Information

Full details

This Kenable RJ11 to RJ45 Cable is for users needing to connect ADSL modems or routers to filtered faceplates, or to route phone lines through dedicated LAN cabling. Its key benefit is providing a reliable wired connection for broadband setups. A potential caveat is its specific use for ADSL and phone line integration, not general networking.

FAQs

Can this cable be used for standard Ethernet networking?

No, this cable is specifically wired for ADSL broadband and phone line connections. It uses RJ11 on one end and RJ45 on the other with straight-through wiring, which is different from standard Ethernet pinouts.

What is the difference between this cable and a standard Ethernet cable?

Standard Ethernet cables typically use RJ45 connectors on both ends and have specific wiring for data networking. This cable uses RJ11 on one end and RJ45 on the other, with wiring optimized for ADSL signals and phone lines.

Will this cable work with a VDSL or Fibre modem?

This cable is primarily designed for ADSL. While some VDSL modems might have an RJ11 port, its effectiveness depends on the specific requirements of your VDSL service and equipment. It's best suited for ADSL connections.

How do I connect my phone line through my network cabling using this?

Connect the RJ11 end to your modem/router, and the RJ45 end to a wall socket that is wired back to another RJ45 socket where you want your phone line to terminate. Ensure the internal wiring is correctly configured for phone line pass-through.

What does 'flat four core cable' mean?

It refers to the physical construction of the cable, which is flat and contains four individual wires inside. This design is often used for telephone and ADSL connections.

Is the 5m length sufficient for most setups?

Yes, 5 meters is generally adequate for connecting a modem or router to a wall socket in a typical room, providing flexibility without excessive cable slack.

Troubleshooting

No ADSL connection

Verify both RJ11 and RJ45 connectors are fully seated. Ensure the cable is connected to the correct ADSL port and not a standard phone line socket if using a filtered faceplate. Test with a different known working cable if possible.

Slow internet speeds

Check for any physical damage to the cable. Ensure the cable is not running parallel to power cables for extended periods, which could cause interference. Confirm your ISP and ADSL equipment are functioning correctly.

Cable does not fit

Confirm you are attempting to connect to an RJ11 port (typically smaller, for phone lines) and an RJ45 port (larger, typically for network cables). This cable will not fit standard telephone jacks (BT-style) or standard Ethernet ports if used incorrectly.

Pros and Cons

Pros

  • Facilitates direct ADSL modem/router connections.
  • Allows phone lines to utilize existing structured network cabling.
  • Simple and reliable straight-through wiring.
  • Adequate 5m length for typical home or office use.

Cons

  • Primarily for ADSL and phone line use, not general Ethernet networking.
  • Flat cable design might be less ideal in some tight-fitting conduit situations compared to round cables.
  • Requires compatible RJ11 ports on one end (modem/faceplate) and RJ45 on the other (for LAN routing).

Setup, Compatibility & Care

Setup: Simply plug the RJ11 connector into your ADSL modem or router's phone port and the RJ45 connector into the corresponding port on your filtered faceplate or wall socket. Ensure connections are secure.

Compatibility: This cable is designed for ADSL broadband connections and phone line signal transmission. It is not a standard Ethernet cable for connecting computers to networks or routers to the internet WAN port. It requires an RJ11 port on one end (e.g., modem, router, or faceplate) and an RJ45 port on the other, typically used for routing phone signals via network cabling.

Care: Keep the cable clean and free from dust. Avoid sharp bends or kinks, especially near the connectors, to maintain signal integrity. Store in a dry place when not in use.
