Abstract

An optical switch assembly comprising at least two optical amplifiers (10, 20), means for applying a first input signal to one end of both amplifiers (10, 20) and a second input signal to another end, and means for simultaneously driving one or other of the amplifiers into a saturated state whilst the other is unsaturated such that only the amplifier that is unsaturated provides any significant amplification to the input signals at each end, and means for feeding the amplified output signals from the amplifiers to at least two output nodes such that the two amplifiers (10, 20) are connected to the two output nodes in opposite connections.
