Eaton N390B-40M-1X2AP 40 m OS2 8-Fiber MPO Breakout Cable

Break out one eight-fiber optical path into two four-fiber legs without placing a separate breakout panel in the cable route. Eaton N390B-40M-1X2AP is a 40 m singlemode fiber breakout cable built around 8.3/125 µm OS2 fiber. Its trunk end uses one 8-fiber APC MPO female connection, providing a defined interface for high-density fiber cabling. The 1x2 construction supports runs where an eight-fiber MPO connection needs to divide into two downstream four-fiber paths. This topology helps preserve fiber organization between a high-density trunk connection and equipment, patching, or distribution points that use smaller fiber groups. The 40 m length suits cross-room, row-to-row, and intermediate-distribution runs where short patch leads are insufficient. OS2 singlemode fiber is intended for singlemode optical infrastructure rather than multimode-only plant. The 8.3/125 µm construction identifies the fiber type required when matching the cable to existing singlemode trunks, transceivers, panels, and connection standards. Verify the mating interface and polarity requirements at both the 8-fiber MPO end and the two four-fiber breakout legs before installation. This specific cable distinguishes itself through its 40 m reach, one-to-two eight-fiber-to-four-fiber breakout topology, and APC MPO female trunk connection.
