Lucina™ is a graded index-plastic optical fiber made of "CYTOP~®" per-fluorinated polymer glass by Asahi Glass. Lucina™ offers a new type of optical fiber in premises which is different from glass optical fiber and the polymethylmethacrylate (PMMA) based plastic optical fiber (conventional POF). Conventional POF offers ease of use and excellent cost-performance due to its large core and flexibility. However, the limitation of a 650-nm-wavelength light source and the transmission length of less than 50 m limits conventional POF''s applications. Multi-mode glass optical fiber (MMF) and single-mode glass optical fiber (SMF) offer high bandwidth and long transmission distance but with difficult and expensive connection due to their small core.
