Crystal-Clear Communication & Stable Internet
A degraded telephone cable can cause static on voice calls, failed fax transmissions, and frequent ADSL internet dropouts. Our RJ11 Telephone Extension Cable is engineered with high-quality copper conductors to maintain absolute signal integrity. Whether you are extending a landline phone to your bedside table or moving your DSL modem to a central location for better Wi-Fi coverage, this cable ensures your connection remains fast, clear, and uninterrupted.
Universal 4-Pin RJ11 Compatibility
Not all phone cables are wired the same. This cable features a standard 4-pin configuration (6P4C), making it universally compatible with almost all telecommunication devices. It plugs directly into standard wall jacks, landline telephones, fax machines, answering machines, and ADSL/VDSL broadband modems. The secure, click-in RJ11 male connectors prevent accidental disconnections during use.
Flexible Lengths for Clean Cable Management
Stop stretching cables tightly across the room, creating tripping hazards. We offer this cable in five convenient lengths: 3m, 5m, 10m, 20m, and an extra-long 30m. The flexible white PVC jacket allows you to route the cable neatly along baseboards, under carpets, or around door frames, keeping your home office or living room looking professional and clutter-free.
💡 Pro Tip from Our Technicians
"If you are using this cable to extend your ADSL or VDSL broadband modem, always ensure you plug it into the 'Modem' or 'DSL' port of your microfilter, not directly into the wall socket, to prevent internet dropouts when the phone rings! While a 30m cable gives you great flexibility, remember that extreme lengths on older copper networks can slightly impact DSL sync speeds. If you are setting up a complex home office network and aren't sure whether you need RJ11 or RJ45 cables, drop by our Sham Shui Po store. Our team at Sun Cheong Computer Co. Ltd. will help you map out the perfect networking solution on the spot."

FAQ Section
FAQ Section
- Will this cable work for my ADSL broadband router?Yes, absolutely. This cable features a 4-pin RJ11 configuration, which is the standard requirement for connecting an ADSL or VDSL broadband modem/router to your wall socket or microfilter.
- What is the difference between RJ11 and RJ45?RJ11 is a smaller connector typically used for analog telephone lines and DSL modems (it has 4 or 6 pins). RJ45 is a larger connector used for Ethernet network cables (like Cat5e or Cat6) to connect computers to routers. This product is an RJ11 cable.
- Does using a 30-meter cable affect my internet speed or call quality?For standard voice calls and faxing, 30 meters will not cause any noticeable drop in quality. For ADSL internet, while the cable is high quality, extending the analog line by 30 meters can sometimes slightly reduce maximum sync speeds depending on your ISP's infrastructure. For the best internet speeds, we recommend keeping the RJ11 cable as short as possible and using a long RJ45 Ethernet cable to reach your computer instead.
