RJ11 connector

Product Overview

The 6 wires in a RJ11 connector are divided into 3 pairs: the first is striped blue and white, the second is orange and white, and the third pair is green and white. The combination of these wires usually carries data or voice. A single-phone line uses only one pair of wires. A two-telephone line uses two pairs, and the third pair of wires could be used for a third line. Most dial-up computer modems are typically plugged into a RJ11 jack, whether for Internet connection or a local area network. RJ11 jacks are typically used for fax, modem, and telephone. A RJ11 plug can also be plugged into a RJ45 jack.
