Active Optical Breakout Cable — 40G QSFP+ to 4 × 10G SFP+ — Cisco-Compatible QSFP-4X10G-AOC
This 40G QSFP+ to 4 × 10G SFP+ Active Optical Cable (AOC) is a high-quality breakout assembly for short reach 40G Ethernet. One end presents a single 40G QSFP+ interface, while the far end fans out to four independent 10G SFP+ connectors — a cost-effective way to split a 40G uplink into multiple 10G switch, server, or storage ports without separate optics and patch cords.
- 40G to 4 × 10G breakout — Efficiently fans a single QSFP+ 40G port into four standard 10G SFP+ links for TOR and spine/leaf architectures.
- Cisco-compatible coding — Built to operate as a Cisco QSFP-4X10G-AOC-compatible assembly for use in Cisco 40G switches and platforms that support breakout AOCs.
- Integrated active optics — Low-power electronics and multimode fiber deliver clean 40G/10G links over short distances with minimal EMI.
- Lightweight & easy to route — Thinner, more flexible than copper DACs, improving airflow and cable management in dense racks.
- Hot-pluggable design — QSFP+ and SFP+ ends insert directly into standard cages; no separate transceivers required.
- 100% inspected & tested — Each cable is optically inspected and link-tested for 40Gbps operation and RoHS compliance before shipping.
- Custom cuts available — Standard meter lengths are stocked, and made-to-order lengths can be built to match your exact rack layout and dressing plan.
