No energy loss in fiber optic cables? (Score: 1) by email@example.com on 2014-03-18 14:12 (#NF) I think that getting rid of attenuation would be the actual breakthrough here. Probably breaking some fundamental law of physics too. Re: No energy loss in fiber optic cables? (Score: 1) by firstname.lastname@example.org on 2014-03-18 14:25 (#NG) "no energy loss" was obviously a poor choice of words, but I'm guessing they're referring to the signals within the detector itself which would be very small distances where the difference in attenuation between optical and metal conductors could be very meaningful.
