Tray for storing optical fiber

A rack for storing electrical equipment includes a columnar frame formed by combining a vertical frame and a horizontal frame and a connecting member attached to the horizontal frame. The horizontal frame has a first portion including the connecting member and a second portion other than the first portion. The connecting member is movably attached to the second portion so that an inside of the rack is opened in the first portion.

Rack for storing electrical equipment

A bracket for attaching an optical unit to a rack is provided. The bracket comprises a bracket body and a fastener. The bracket body has a first wall including a first face and a second face opposite to the first face, and a protrusion extending in a direction intersecting with the first wall from the second face against the first face. The bracket body is provided with a hole penetrating through the first wall from the first face to the second face. The fastener is arranged to pass through the hole on the first wall and is configured to be rotatable with respect to the first wall. The fastener has a first hook including a holding surface substantially parallel to the second face. The holding surface of the first hook faces the second face to define a first gap between the holding surface and the second face of the first wall at least when the fastener rotates from an initial position to a first locking position.
