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. Network Racks Cable Management Length Typical Cisco Reference Typical Use 1 Meter QSFP-4X10G-AOC1M* Within the same rack / adjacent chassis. 3 Meters QSFP-4X10G-AOC3M* Most common TOR-to-server or TOR-to-TOR runs. 5 Meters QSFP-4X10G-AOC5M* Across cabinets in the same row. 10 Meters QSFP-4X10G-AOC10M* Longer row-to-row connections in a single room. Custom Built to match Cisco length families Work with Gruber for custom cuts, labeling, and bundling tailored to your data-center layout. *Cisco part numbers shown as typical references only; this is a compatible, third-party breakout AOC. Why choose Gruber for your Cisco-compatible AOCs Curated, Cisco-compatible optics — We select and qualify breakout AOCs specifically for Cisco 40G/10G environments, not just generic catalog parts. Custom cuts & rack-ready builds — Gruber can cut to exact length, label ends, and bundle harnesses so your racks are neat, serviceable, and consistent across sites. End-to-end data-center expertise — From UPS and power to racks, cabling, and optics, we understand real-world installations and can help you design the right connectivity plan. Project support, not just boxes — Whether you’re turning up a single cabinet or an entire row, Gruber can stage, document, and ship matched cable sets that align with your Cisco BOM and deployment schedule.
