Array type 256-core superfine cluster optical fiber FA assembly

The utility model relates to the technical field of bundled optical fibers, and provides an array type 256-core superfine bundled optical fiber FA assembly, which comprises an optical fiber fixing ring, a stainless steel hose, an array assembly shell and bundled optical fibers, the bundled optical fibers are formed by arranging 256-core optical fibers in a straight line, a straight-line-shaped V-groove array block is clamped on the outer side of the end of each bundled optical fiber, and the stainless steel hose is arranged in the array assembly shell. A T-shaped array fixing block used for positioning the linear V-groove array block in the array assembly shell is clamped outside the linear V-groove array block; the linear V-groove array block is formed by assembling an upper block and a lower block, 256 V-shaped grooves which are tightly arranged are formed in the center of the upper portion of the step face, the distance between the grooves is equal to the diameter of a superfine-diameter optical fiber, and
