Abstract
An optical fibre-amplifier and a transmission system with such a fibre-amplifier is proposed, in which the fibre-amplifier has an amplifying fibre-component with optical fibre-amplifier (2) and at least one optical component (6) which possesses a temperature behavior, which compensates the effects on the optical behavior of the fibre-amplifier.
Claims9
An optical fibre amplifier (1) comprising at least one active component of an amplifying fibre doped with a rare-earth element (2) and at least one optical input (3) and at least one optical output (4), where the optical input and outputs are connected with a fibre-transmission section (5), characterised in that the amplifier (1) comprises at least one passive optical component (6) which comprises a material which possesses an inherent optical behavior with variation in temperature, which is opposite to the optical behavior of at least the amplifying doped fibre (2).
A transmission system with at least one optical fibre-amplifier with at least one station and one recipient, characterised in that the fibre-amplifier is stabilized in its optical behavior at varying temperature by the use of balancing optical components.
