Abstract
The present invention relates to an optical fiber product suitable for fabricating an optical cable that requires a complicated length adjustment. The optical fiber product includes an effective use portion used as the optical cable, surplus portions connected to both ends of the effective use portion, and a distinguishing structure clearly indicating boundary portions between the effective use portion and the surplus portions. With the above structure, the surplus portions that become finally unnecessary are surely cut off in a fabrication step of the optical cable, thus enabling collect use of only effective use portion as the optical cable.
