4.6 Conclusion to Section 4

This brief account has introduced a few of the most rapidly developing areas of optical-fibre communications as of January 2004. By the time you are reading it things will certainly have moved on, and if you want to find the current state of the art you should read journals such as IEEE Communications Magazine or trade magazines such as Lightwave. It is also possible to find out more on the world wide web.

I hope you will agree that this is a fascinating field, and that you will be encouraged to study it further.
