Abstract

For connecting two light-conducting fibers 1, 2, a ferrite tube 3, 4 is fixed to the end of each fiber. According to Fig. 1, ferrite tubes 3, 4 are magnetized such that at the junction of the two light-conducting fibers opposite magnetic poles N and S face, and thus attract, each other. Over the first ferrite tube 3, 4 of each light-conducting fiber 1, 2 a second ferrite tube 5, 6 is mounted with a short spacing, whose magnetization is opposite to that of the first, as shown in Figs. 1 and 2. By lapping the combination of magnet and fiber, a plane surface is obtained for connection. The described connector has the following advantages: It is resistant to vibration and shock. It ensures that there is no end separation of the fibers after connection. It prevents angular and axial misalignment.

Fiber-Optic Cable Connector With Magnetic Alignment

For connecting two light-conducting fibers 1, 2, a ferrite tube 3, 4 is fixed to the end of each fiber. According to Fig. 1, ferrite tubes 3, 4 are magnetized such that at the junction of the two light-conducting fibers opposite magnetic poles N and S face, and thus attract, each other. Over the first ferrite tube 3, 4 of each light- conducting fiber 1, 2 a second ferrite tube 5, 6 is mounted with a short spacing, whose magnetization is opposite to that of the first, as shown in Figs. 1 and 2. By lapping the combination of magnet and fiber, a plane surface is obtained for connection. The described connector has the following advantages: It is resistant to vibration and shock. It ensures that there is no end separation of the fibers after connection. It prevents angular and axial misalignment. Only two types of ferrite tubes are required. Their magnetization may be color-coded so that fiber- optic and ferrite tubes can be readily assembled.
