Abstract
The present invention discloses an optical fiber cable of diameter D (mm) in which an adhesive layer having a thickness of 0.5 to 200 &mgr;m, a primary coating layer and a secondary coating layer are sequentially formed around the outside of an optical fiber in which the outermost layer is composed of vinylidene fluoride polymer; wherein, in the case the diameter of the optical fiber is represented with Da (mm), the thickness of the adhesive layer is represented with d (mm), and Da+2d is represented with D , then D /D =1.2 to 3.5, and an optical fiber cable with plug that uses this optical fiber. Thus, the resulting optical fiber cable has superior flame resistance, is resistant to peeling of the optical fiber and coating layers, and is resistant to the occurrence of pistoning phenomenon. The optical fiber may also be composed of a core, a sheath formed around the core, and a protective layer formed around the sheath.
