Split a high-density MPO APC optical connection into four LC duplex paths over 40 m of OS2 single-mode fiber. The yellow breakout assembly gives a QSFP-type optical connection a direct fan-out to equipment or patching that terminates on LC duplex interfaces, retaining the connector transition in one cable run. Axiom Memory MP8LCSMR40M-AX combines an MPO APC end with four LC duplex ends, making it suited to link architectures where an MPO-based transceiver-side connection must fan out into four separate duplex pairs. OS2 single-mode construction supports long-reach single-mode optical channel designs, while the 40 m length provides routing latitude for cross-row, room-to-room, or cabinet-to-distribution-frame paths without splicing. Select this assembly when both connector topology and fiber type must match: MPO APC on the aggregated end, four LC duplex branches on the breakout end, and OS2 single-mode fiber throughout. Its yellow outer color makes the single-mode cable type readily distinguishable during installation and trace work in dense pathways.
