Abstract
An optical fiber cable having a diameter of D (mm) and comprising an adhesion layer 0.5 to 200 &mgr; in thickness, a primary coating layer, and a secondary coating layer, all sequentially formed on the outer circumference of an optical fiber constituted on the outermost layer thereof by vinylidene fluoride polymer, wherein D /D =1.2 to 3.5 (the diameter of the optical fiber is Da (mm), the thickness of the adhesion layer d (mm), and Da+2d=D ); and an optical fiber cable with a plug using this optical fiber. Accordingly, these optical fiber cables are excellent in flame resistance, difficult in separating an optical fiber thereof from coating layers, and not likely to cause a pistoning phenomenon. An optical fiber may consist of a core, a sheath formed on the periphery of the core and a protection layer formed on the periphery of the sheath.
