摘要： This invention relates to a subrack device applicable for an SDH network, and more particularly to a subrack device which can be produced flexibly in response to a customer's need. The subrack device has a subrack body commonly used regardless of a type of the subrack device. The subrack body has a circuit-board-unit housing portion and an outer-connecting-board mounting portion. Circuit boards and outer-connecting-board connecting-boards of different types are prepared. The outer-connecting-board mounting portion has a plurality of outer-connecting-board mounting territories. The outer-connecting-boards are plugged in the outer-connecting-board mounting territories to produce the subrack device meeting the customer's need.

摘要： An optical communication device comprising a horizontally rectangular main shelf, and a horizontally rectangular sub-shelf arranged in a vertically overlapping relationship with the first shelf. The main shelf and the sub-shelf have parallel guide rails in register with each other. Unit plates comprising optical modules for optical-electrical signal conversion are inserted in the main shelf in upright positions for engagement with the respective guide rails. Optical fiber supporting plates having means for supporting the optical fiber having a surplus length portion coiled in a freely extendable manner are inserted in the sub-shelf in upright positions for engagement with the respective guide rails. Accordingly, the surplus length portions of the optical fibers are orderly arranged in correspondence with the optical modules so as to prevent an incorrect connection between the optical fibers and the optical modules.

摘要： A cooling device able to blow cooling air in a larger amount than a conventional amount and in addition selectively with respect to a specific cooled element even in a case where an area of an intake port which can be secured in a front surface of a case to be cooled inside is restricted small. This cooling device is constituted by an air duct spread in a bag shape from the intake port into the case. At least a group of small openings oriented to the cooled element is provided in a wall of this air duct. Then, cooling air is blown from this group of small openings for the cooling.
