Description

This group is for those interested in long distance optical communication.

In July 2005, at the GippsTech conference, Chris Long gave a presentation on long distance optical communications and his efforts in setting a new world record for voice communication using non-coherent light. This presentation was repeated to a number of groups and has stirred up a lot of interest in optical communications.

As a result, this group has been set up to enable discussion of optics, electronics, construction and operation of long distance optical systems.

Re: Pulse width modulated high frequency laser driver
Hello, for a high speed application you might have to use an accousto-optic modulator, also abbreviated AOM.
