Claim of US Patent No. 10,012,808

1. An optical fiber strip comprising:a stair-shaped base element having:
a first receiving surface on a first stair of the stair-shaped base element;
a second receiving surface on a second stair of the stair-shaped base element;
a plurality of holes integrally formed and extending from the first receiving surface to a bottom surface of the stair-shaped base element; and
a first bearing surface connecting the first receiving surface and the second receiving surface;
a cover element comprising:
a first end;
a second end;
a first curved part having a first covering surface forming a first stair of the cover element at the first end;
a second curved part having a second covering surface forming a second stair of the cover element at the first end;
a second bearing surface connecting the first covering surface and the second covering surface of the cover element; and
an internal curved space between the first curved part and second curved part extending from the second end to the second bearing surface;
an adapter configured to be selectively connected to an external optical fiber array; and
an internal optical fiber array connected to the adapter and the plurality of holes passing through the internal curved space to be selectively and optically coupled to an optical-electrical conversion unit on the bottom surface of the stair-shaped base element, and configured to receive or transmit at least one optical signal from the external optical fiber array via the adapter or from the optical-electrical conversion unit via the plurality of holes, wherein a curved portion of the internal optical fiber array is located in the internal curved space for changing direction of the internal optical fiber array;
wherein at least one of the first bearing surface and the second bearing surface has a plurality of grooves forming a plurality of pathways connecting the internal curved space to the plurality of holes when the first receiving surface, the second receiving surface, the first bearing surface of the stair-shaped base element are respectively join to the first covering surface, the second covering surface, and the second bearing surface of the cover element, the internal optical fiber array is extended from the internal curved space and inserted to the plurality of holes, the internal optical fiber array is positioned according to a hole pattern of the plurality of holes in the stair-shaped base element, the internal optical fiber array is curved according to a radius of curvature of the internal curved space in the cover element, and position and a radius of curvature of the internal optical fiber array are determined by the stair-shaped base element and the cover element respectively.
