Multimode couplers are passive optical devices which allow the distribution and
combination of optical signals. They are used in private fibre-optic networks as
nodes in data transmission networks. Further fields of application are measurement
set-ups, measuring instruments, sensor and automation systems.
The couplers are manufactured on the basis of a combination of etching technology
and the Fused Biconical Taper (FBT) principle.
