On the B777 it's the OLAN (onboard local area network) that was fibre optic & as Spanners says it's controlled by AIMS & is used in AVLAN (avionics local area network), CMCS (central maintenance computing system) MAT, CABLAN (Cabin local area network) &
CMS (cabin management system). It's been dropped on the B777ER.
