OPTiFab 1U rack-mounted Sliding Patch Panel is available unloaded or pre-loaded with up to 24 duplex adapters, multi mode or single mode. It features 4x 20mm cable entry/exit holes, and 2x 10mm blown fibre holes. The panel features an interchangeable face plate, meaning if you decide to change connectors and adapters in a certain network, you can replace the face plate without needing to change the whole panel. Can be preloaded with pigtails. The panel\'s lower tray features punched screw holes for securing our fibre management trays, and pressed loops for securing fibre in place. The panel is constructed from cold-rolled steel, and finished with a durable and aesthetic matte-black powder-coating. Other finished such as grey powder-coat and natural stainless steel are also available.
