(...) une évaluation de lignes bus électriques est faite aux USA sur le bombardier Rockwell B-1 en vue de déboucher sur son équivalent optique. Un bus optique permettrait des vitesses de transmission supérieures à 10 Mbits/s au lieu de 1 Mbits/s, un nombre d'abonnés sur la ligne bien supérieur, que dans le cas de son homologue électrique.
