EDFA

[JAKO Andras <goya () eik bme hu>]

 Hello,

A bit off-topic and maybe stupid question:

I was told yesterday, that a Hungarian telco/ISP is experimenting with
EDFAs. My friend said that the box looks like if they just brought it from
a research lab (however it's a commercial product). How common is it
nowadays to use EDFAs in ISP backbones?

Please reply me off-list. Thanks.
