AO Modulator

M111-2J-FxS

  • 1550nm fibre-coupled

  • As fast as 25ns rise-time

  • 111MHz frequency shift

Description

A fibre-coupled acousto-optic modulator suitable for use in telecommunications applications. Designed to provide the highest bandwidth all-optical switching available, it also exhibits excellent extinction ratio and low polarisation sensitivity.

 

In addition to the two fibre version, a three fibre model allows both zero and first order output beams to be utilised. Other options include a choice of operating wavelengths and fibre connectors.
