Abstract
An optical fiber ribbon includes: optical fibers disposed side by side in a predetermined direction; and connecting portions that connect two adjacent ones of the optical fibers. A peripheral resin portion is formed on a periphery of the optical fibers. An arithmetic mean roughness Ra of a surface of the peripheral resin portion is 0.41 μm or lower. A ten-point mean roughness Rz of a surface of the peripheral resin portion is 1.4 μm or lower.

An optical fiber ribbon, comprising:
- optical fibers disposed side by side in a predetermined direction;
- and
- connecting portions that connect two adjacent ones of the optical fibers, wherein
- a peripheral resin portion is formed on a periphery of the optical fibers,
- an arithmetic mean roughness Ra of a surface of the peripheral resin portion is 0.41 μm or lower,
- a ten-point mean roughness Rz of a surface of the peripheral resin portion is 1.4 μm or lower, and
- the arithmetic mean roughness Ra of the peripheral resin portion is 0.41 μm or lower and the ten-point mean roughness Rz is 1.4 μm or lower when the connecting portions of the optical fiber ribbon are broken to separate the optical fibers and thereafter the surface of the peripheral resin portion is measured along a longitudinal direction of the optical fibers so as to prevent the broken portions of the connecting portions from being measured portions.
