Abstract
A spacecraft or satellite optical transmission apparatus (10) including an optical fiber (11) and at least one optical pump source (14) operatively coupled to provide pump energy to the optical fiber (11), the optical fiber (11) comprising an active trivalent dopant such as erbium and at least one passive trivalent dopant such as lanthanum. A method for transmitting electromagnetic radiation in a high radiation environment is also disclosed.
