The Wirewerks NEXT STEP splice tray is a revolutionary high-density splice tray with unique cable routing features. It is the only splice tray on the market that can route all cable types with ease - including ribbon fiber, loose tube and tight-buffer. At just under half an inch thick, it has a capacity of up to 24 fibers and 2 bare fiber splitters. This means a total of 288F fit neatly in a 1U space when used with our NEXT STEP 1U rack mount patch panel.
