Structured fiber optic cabling system including an array of ports and orthogonally arranged jumper assemblies

A structured optical fiber cabling system configured to connect first and second layers of switches in a mesh network is disclosed. The system comprises groups of fiber optic ports arranged side-by-side, with each group including a plurality of the fiber optic ports distributed in a vertical direction. A plurality of fiber optic jumper assemblies each include a horizontal segment and a plurality of legs and fiber optic connectors extending from the horizontal segment, with each fiber optic connector configured to connect to a corresponding fiber optic port of the plurality of the fiber optic ports at the same vertical location in each group of the array.
