A 1:4 ratio splitter will divide a beam of fiber optic light into four equal beams of light. While a power strip is limited by the number of sockets, a fiber splitter is limited by the shared data stream coming from a single OLT port. It is a crucial part of many optical experimental and measurement systems, such as interferometers, also finding widespread application in fibre optic telecommunications. Edmund Optics offers plate, cube, pellicle, polka dot, or specialty prism Beamsplitters in a variety of anti-reflection coatings or substrates. 24 coating) together to minimize wavefront distortion. The hypotenuse of one of the prisms is coated with a multilayer dielectric polarizing beamsplitter.
