Cisco QSFP‑4X10G‑AOC3M Full English Product Description

Cisco QSFP‑4X10G‑AOC3M is an original Cisco active optical breakout cable with a fixed length of 3 meters. One end features a QSFP+ connector, while the fan‑out side delivers four independent SFP+ optical interfaces. Built with VCSEL array and PIN receiver technology over multi‑mode fiber, it complies with QSFP+ MSA SFF‑8436, SFP+ MSA SFF‑8431 and IEEE 802.3ba standards. It converts one 40G QSFP+ port into four independent 10G SFP+ channels for medium‑range intra‑rack and cross‑rack interconnections within enterprise, cloud and high‑performance computing data centers, eliminating copper‑related signal attenuation and EMI constraints.

40G Aggregated / 4×10G Full‑Duplex Optical Transmission

Supports 40GBASE‑SR4 aggregated bandwidth, breaking out into four independent 10GBASE‑SR channels. Ideal for 40G‑to‑4×10G port expansion for leaf‑spine fabrics, switch‑to‑switch and switch‑to‑server interconnections.
Active Optical AOC Architecture

Integrated VCSEL transmitters and PIN photo‑detectors on both QSFP+ and SFP+ ends. Optical transmission overcomes the distance‑limitation drawbacks of copper DAC cables. Supports Digital Diagnostic Monitoring (DDM) via I2C bus for real‑time cable health monitoring.
Light‑Weight Flexible Optical Cable Design

Much lighter and more flexible than twinax copper assemblies, meeting strict minimum bend radius requirements. Improves airflow and simplifies cable management inside high‑density rack environments.
Hot‑Swappable QSFP+ and SFP+ Interfaces

Standard hot‑pluggable QSFP+ host connector and four SFP+ fan‑out connectors. Technicians can insert or remove the cable without powering down connected Cisco switches, routers and servers.
Robust Multi‑Mode Fiber Assembly

Ribbon multi‑mode fiber construction provides excellent electromagnetic immunity, completely resistant to EMI / RFI interference and near‑end crosstalk in dense data‑center deployments.
Standard Pull‑Tab Latch Design

Equipped with pull‑tab latches on the QSFP+ and each SFP+ connector for convenient insertion and extraction from network hardware ports.
