Fibre optic cables’ data capacity may soon be reached

Technology may stretch the capacity of the fibre optic cables used to carry data sooner than has long been thought, according to a report in Science.The capacity limit has until recently been in the preparation of the light signals that pass through the cables.But the report reviews recent laboratory results showing data rates that are more than half the ultimate limit of fibre optic cables.It calls for urgent research to develop higher-bandwidth cables.To read this BBC News report in full, see:
