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 electrical component accommodating portions (11) and (12) and the optical component accommodating portions (21) and (22) are configured to accommodate one or both of the optical component and the electrical component, and are laminated in the Z direction. The housing (1) is configured to accommodate the stacked electrical component accommodating portions (11) and (12) and the optical component accommodating portions (21) and (22) with the X direction as the longitudinal direction. The heat radiating members (2) to (4) are provided in the housing (1) and house the heat generated in the electric component accommodating portions (11) and (12) and the optical component accommodating portions (21) and (22). Conduct to the body (1).
