Neos Technologies Inc. has launched an acousto-optic fiber switch suitable for applications such as node bypassing, data switching and fiber testing. The switch is available in 1 x 1, 1 x 2 and 2 x 2 configurations and integrates the radio-frequency driver and acousto-optic switch in a rack-mountable enclosure. The system achieves 100-ns switching speeds for use in the S-, C- or L-bands. The company says the switch allows turnkey operation and high throughput. A dual-band system designed for fast switching between the C- and L-bands is also available.
