- 12 - FAULT TOLERANT OPTICAL AMPLIFIER ARRANGEMENT Abstract of the Disclosure For a group of optical amplifiers, pump beams from an array of lasers are mixed together to form a plurality of composite pump beams. Each composite pump beam is distributed to the pump port of a particular optical amplifier. The composite pump beam improves the reliability of each optical amplifier. Rather than having catastrophic failure of an optical amplifier occasioned by the failure of its pump laser, it is now possible to maintain fulloperation of the group of optical amplifiers even though one or more lasers fail.
