Reasons for low extinction ratio in fiber optic couplers
Splice free, cascaded assemblies, of polarization maintaining components, having very low extinction ratio and low loss, give superior performance to spliced components. Extinction ratio shows how well a system tells strong signals from weak ones. A bigger number means the signal is better. Fiber optic signal paths that include splices, connectors, PM couplers, and input - output alignment devices, generally show. Thus it is important to exactly align the polarization axis of the laser source with the polarization axis of the fiber e. This method creates a simple, rugged, compact method of splitting or combining.
