Eaton N390B-19M-1X2AP 19 m OS2 MPO Breakout Cable

Split a single 8-fiber OS2 fiber path into two 4-fiber branches with a 19 m breakout assembly. Eaton N390B-19M-1X2AP uses 8.3/125 µm singlemode fiber and presents one 8-fiber APC MPO female connection at the trunk side. The breakout format preserves the eight-fiber path while separating it into two four-fiber groups for downstream connection architecture. Use this cable where an MPO-based singlemode backbone must transition from one eight-fiber trunk connection to two smaller fiber branches without placing a separate breakout enclosure at the transition point. Its 19 m length supports inter-rack, row-to-row, or equipment-to-distribution-frame routing where a short patch lead would not reach. OS2 fiber is suited to singlemode optical infrastructure and long-reach fiber channel planning. The specific configuration combines three defining details: one 8-fiber MPO input, two 4-fiber breakout branches, and an APC MPO female interface. Those details matter when matching fiber counts and MPO end-face requirements at the trunk side. Confirm the required branch-end interface, routing path, and optical equipment connection requirements before installation, particularly where the two four-fiber branches serve separate equipment paths.
