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.
Claims11
A method for measuring power loss in a fiber optical connector including an optical fiber for transmitting high optical power exceeding 1 kW, the method comprising:
- at least partially absorbing in a flowing coolant incident radiation falling outside the fiber core;
- and
- detecting a temperature difference between ingoing coolant and outgoing coolant heated by the incident radiation, thereby providing a measurement of a generated power loss due to incident radiation absorbed by the coolant.
An apparatus for measuring power loss in a fiber optical connector including an optical fiber for transmitting high optical power exceeding 1 kW, and wherein incident radiation falling outside the fiber core is absorbed at least partially in a flowing coolant, wherein the connector comprises a detector for detecting a temperature difference between ingoing coolant and outgoing coolant heated by the incident radiation, thereby providing a measurement of a generated power loss due to incident radiation absorbed by the coolant.
A fiber optic contact, comprising:
- an optical fiber for transmitting high optical power exceeding 1 kW;
- a connector;
- a coolant flowing in the connector and operative to at least partially absorb incident radiation falling outside a core of the fiber;
- and
- a detector operative to detect a temperature difference between ingoing coolant and outgoing coolant heated by the incident radiation, thereby providing a measurement of a generated power loss due to incident radiation absorbed by the coolant.
