Cisco QSFP-4 x 10G-AOC5M – Multimode – Active Optical Breakout Cable

Active Optical Breakout Cable — 40G QSFP to 4 × 10G SFP (AOC, Multimode) — Cisco-Compatible QSFP-40G-4S-AOC (5m shown) This multimode (MMF) Active Optical Cable breaks out a single 40G QSFP port into four 10G SFP links — ideal for switch-to-server or switch-to-switch fanout where you want clean, lightweight fiber routing without managing separate transceivers and patch cords. True breakout (1-to-4) — QSFP on one end to four SFP connectors on the other. Multimode fiber AOC — optics are built into the ends (no separate modules required). Clean install — thin, flexible aqua jacket for tidy racks and easier cable management. Data-center friendly — hot-pluggable ends and quick port-to-port deployment. Compatibility-first — programmed for Cisco-style interoperability (verify platform support).
