Singlemode-Coupler-Modules
Optical coupler modules are passive optical devices which allow the distribution and combination of optical signals. They are used in public and private fibre-optic networks as nodes for data transmission (telephone, cable TV etc.); further fields of application are in measurement set-ups, measuring instruments, and sensor technology. The basic couplers are manufactured on the basis of an advanced Fused Biconcal Taper (FBT) technology to provide optimum performance and longtime stability. The coupler modules consist of a set of different or identical fusion couplers.
