Couplers, Splitters & Combiners

Plastic Fiber Couplers/Splitters

Our PLAC plastic fiber couplers/splitters distribute incoming optical signals across multiple output fibers. These couplers utilize high-performance plastic optical fibers with a diameter of 1.0 mm with a 0.98mm core and 2.2 mm outer diameter, featuring a core made from polymethyl-methacrylate (PMMA) resin and fluorinated polymer cladding. The 1×2 coupler efficiently splits light 50:50 over a broad wavelength range in the visible spectrum. Larger 1xN and NxN configurations are created by cascading 1×2 couplers, resulting in approximately 3 dB loss at each junction. Couplers are efficient in splitting light but incur significant losses when combining lights. We offer one of the industry’s most comprehensive selections of fused fiber couplers and splitters, designed for a wide range of application scenarios.
