An optical connector device has a first connector including a ferrule for holding an optical fiber and a guide portion projecting longer than the ferrule. The closing component is capable of rising by bending from its closure position. The resultant flow information at the destination corresponds to the effective throughput from the source to the destination, and the flow information at the output of each intermediate element in the network corresponds to the potentially achievable throughput through that element for the given source-to-destination flow. Different trigger events may be prioritized.
