Abstract
Provided is a multi-core optical fiber which is capable of achieving the same level of light receiving capacity as that of a single-core plastic optical fiber, while being reduced in bending loss. A multi-core optical fiber according to the present invention has a plurality of cores and sea portions that are formed around each core. This multi-core optical fiber satisfies at least condition (1) or condition (2) below: (Condition 1): The occupancy rate of the total cross-sectional area of cores is 80˜95% of the outer region in the cross section of a multicore optical fiber. (Condition 2): The occupancy rate of the total cross-sectional area of cores is 82˜93% of the cross section of a multicore optical fiber.
