A system for routing fiber optic jumpers from a fiber optic jumper trough to network equipment includes fiber optic jumper enclosures. Each enclosure has a tubular segment surrounding an interior. The interior of each tubular segment accommodates the placement of fiber optic jumpers within the tubular segment. Some of the enclosures have connector holes in the tubular segments and some of the enclosures have latches connected to ends of the tubular segments. First, second, third, etc., enclosures interconnect with one another to form a router for routing fiber optic jumpers between a fiber optic jumper trough and the network equipment. A latch of the first enclosure connects to a connector hole of the second enclosure in order to interconnect the first and second enclosures to form the router. A post associated with one of the first and second enclosures mounts the router to the network equipment.
