1. Introduction<\/h4>\n

Flat optical cable uses several fibers as optical communication medium. Widely used in Metro ODN\u00a0network especially inside buildings which have multi-floors and room and two parallel fiber reinforced plastics (FRP) are its strength member. The cable is completed with a PE\u00a0jacket.<\/p>\n
