Abstract

A method and apparatus for measuring the power loss in a fiber optical connector of the type which includes an optical fiber for transmitting high optical power, specifically power exceeding 1 kW. Incident radiation falling outside the fiber core is absorbed at least partially in a flowing coolant. The connector includes thermo-elements for measuring a temperature difference between the ingoing and outgoing coolant as a measure of the generated power loss. The flow speed may be adapted to different power losses.
