Tripp Lite's N482-01U is a High Density Fiber Cassette solution that supports up to 5 High Density Fiber Cassettes, maximizing rack space and allowing for up to 60 Duplex LC Ports (120 fiber connections) in just 1U of space. Tripp Lite's High Density Fiber Cassettes come in multiple variations, allowing you to connect different generations of equipment (10Gb, 40Gb, 100/120Gb), and giving you the flexibility to adapt as your technology changes. Installation is simple, with the cassettes being easily installed or removed using push / pull tabs to lock or unlock them from the panel; no tools required. Management is a breeze with an optional rear-mounting cable management bracket that allows you to rout your cabling neatly and safely. A fold-down door panel is featured on the front of the unit, and protects your connections, while rotating out of the way to provide full access. The door panel can also be removed altogether for installations where constant access is preferred. Constructed of heavy-duty steel housing.
