摘要

PROBLEM TO BE SOLVED: To solve a problem that the mechanical strength drops when a lot of chassis an connected to each other although a lot of electric parts and optical parts can be mounted on an optical undersea relay. SOLUTION: A unit 11 is formed by assembling an electric chassis 23 into an optical chassis 21. The plurality of units 11 are connected using connecting chassis 12.
