This 5m long fast modem cable was designed with Broadband in mind. Manufactured to BT standards this fast modem cable has 24 carat gold plated connectors and high quality copper. The PVC sheath is strong and molded for strain relief. Finally while there may be nothing wrong with the cable you got with your modem or router, it probably isn't 5 metres long. This one will allow you to put your computer where you want not necessarily right near the phone socket.
