Patent number: 7298950Abstract: The invention relates to a distribution cabinet (10) for optical fibers, comprising a housing (11) and a frame (18) that is pivotally mounted inside the housing (11). Cables encompassing optical fibers that are guided therein can be routed into and/or directed out of the distribution cabinet, the cables being routed to the frame (18) from a rear side (14) of the housing (11) and being routed away from the frame in the direction of the rear side. Subassemblies are fastened to the frame (18) in order to connect the optical fibers that are guided within the cables. At least one holding device (23) for the cables is fastened to the pivotally mounted frame (18), the cables being fixable to the holding device (23). The holding device (23) is configured so as to be pivotable relative to the housing (11) along with the frame (18), while also being pivotable relative to the frame (18).Type: GrantFiled: September 4, 2004Date of Patent: November 20, 2007Assignee: Corning Cable Systems LLCInventor: Franz-Friedrich Frohlich
