Abstract
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).
