PROBLEM TO BE SOLVED: To solve the problem in which: a connection operation of insertion and withdrawal individually to a plurality of optical modules arranged on a substrate is very complicated in operating a device.SOLUTION: The present invention proposes a structure in which corresponding optical modules of a plurality of optical modules can be integrally optically coupled to each other so as to avoid convergence of edges of substrate wiring and improve throughput. Accordingly, even when the numbers of the optical modules increases on a single substrate, optical coupling can be performed in a short time without impairing maintainability. That is, as the optical modules can be moved integrally with a relay substrate, workability is improved and costs can be effectively reduced. |
