Patent number: 8408810Abstract: In order to realize an exact contacting of optical waveguides in connectors, the invention proposes a connector for optical waveguides, particularly for being mated and contacted with a mating connector that is equipped with an optoelectric receiver, wherein two optical waveguides are respectively arranged within a ferrule housing in a spring-loaded fashion in individual ferrules and can be axially displaced independently of one another. The ferrule housings are also arranged in a sliding housing that is arranged within a surrounding connector housing such that it can be axially displaced by a certain supplementary travel, namely also in a spring-loaded fashion.
