Mitsubishi CK optical fiber CK-10/CK10 CK-20/CK20 CK-30/CK30 CK-40/CK40 are a series of plastic optical fiber (POF) products developed by Mitsubishi Corporation of Japan for the fields of basic lighting and decoration. It uses polymethyl methacrylate (PMMA) as the core material and has the advantages of low attenuation and high light transmittance.

Mitsubishi SK Series Plastic Optical Fibers (SK-10 / SK-20 / SK-30 / SK-40 / SK-60 / SK-80)The Mitsubishi SK series is an industrial-grade plastic optical fiber developed by Mitsubishi Corporation of Japan. It uses a high-transmittance PMMA fiber core and has an outer diameter ranging from 0.25mm to 3.0mm (e.g., SK20 is 0.5mm, SK40 is 1.0mm). These products feature low attenuation (150–200 dB/km), high tensile strength (up to 70N), and excellent bending resistance, making them suitable for industrial automation, PLC systems, sensor signal transmission, automotive MOST networks, medical lighting, and decorative light guides. Compared to the civilian-grade CK series, the SK series offers superior transmission stability and mechanical performance, resulting in higher reliability.
