1RU-SOP Plastic Splice & Patch Swing Out Panel/Shelf is used for applications where rack space is limited and composite plastic is preferred over steel or powder coated aluminum. The unit allows the connection of up to 48 fibers per unit and is compatible with both 19" and ETSI racks. Cables enter at the rear of the shelf on the left hand side and pigtails exit the unit from the front face. The light weight product is easy to install with builtin fiber management.
