Submarine optical transmission equipment and submarine optical communication system

摘要

Provided is a submarine optical transmission device capable of efficiently accommodating optical components and electrical components. The submarine optical transmission device (100) includes a housing (1), an electric component accommodating portion (11), and an optical component accommodating portion (21). The electric component accommodating portion (11) and the optical component accommodating portion (21) are configured to accommodate one or both of the optical component and the electric component, and are laminated in the Z direction. The housing (1) is configured to accommodate the stacked electrical component accommodating portion (11) and optical component accommodating portion (21) with the X direction as the longitudinal direction.
