摘要： The optical fiber cord of the present invention is characterized in having a primary covering layer formed from a polyamide resin that incorporates at least one of an organic acid or an organic acid anhydride on the outer periphery of the optical fiber. In addition, the optical fiber cord with a plug of the present invention has a plug on at least one end of the optical fiber cord of the present invention having a secondary covering layer on the outer periphery, wherein at the end part of the optical fiber cord that has the plug, the primary covering layer is exposed, and the plug is fastened to the exposed primary covering layer. By using the structure described above, an optical fiber cord and an optical fiber cord with a plug that has superior humidity resistance and heat resistance, and in addition can be laid easily in narrow sites because of superior flexibility and is inexpensive. The optical fiber cord and the optical fiber cord with a plug of the present invention can be favorably employed in uses that require thermal resistance such as installation on a vehicle or in factory automation (FA).

摘要： The present invention discloses an optical fiber cable of diameter D1 (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 D2, then D1/D2=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.

摘要： An optical fiber cable having a diameter of D1 (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 D1/D2=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=D2); 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.
