PROBLEM TO BE SOLVED: To provide an optical transmission line card having a low mounted height and a thin configuration, and capable of preventing optical fibers from becoming caught in a rail.SOLUTION: An optical transmission line card includes: an optical fiber insertion hole 15, formed in the vicinity of a front or rear end part 13 or 14 in the insertion direction of a substrate 2 and also formed so as to penetrate the substrate 2, for passing optical fibers 5 mutually connecting optical components 4 therethrough; and a slit 16, formed in the substrate 2, for passing the optical fibers 5 through the optical fiber insertion hole 15 from the front or rear end part 13 or 14 in the insertion direction of the substrate 2. The optical transmission line card is configured such that the optical fibers 5 are passed through the optical fiber insertion hole 15 and housed on front and rear surfaces S and R of the substrate 2. |
