OPTICAL CABLE

摘要

In an optical cable 1, the ratio of the inner diameter ID to the outer diameter OD of a tube 20 is 0.5 or less, and thus the tube 20 has a comparatively thick wall. Consequently, even when the optical cable 1 is bent to a small bend radius of, for example, approximately 2 mm, a kink in a portion of the tube 20 corresponding to the inner side of the bending is suppressed. As a result, damage to a coated optical fiber 10 or an increase in transmission loss arising from the occurrence of a kink in the tube 20 is suppressed.
