Low loss directional coupling for optical fibres |
| abstract |
Low loss directional coupling of optical fibres is obtained by wrapping a tap fibre round a trunk fibre. Any cladding is first removed and then the tap fibre wrapped round the trunk fibre. The tap ratio can be varied by a variation in the number of turns or twists of the tap fibre around the trunk fibre. Signals can be abstracted by the tap fibre and also inserted. |
