Cisco QSFP‑4SFP25G‑AOC1M Full English Product Description

Cisco QSFP‑4SFP25G‑AOC1M is an original Cisco active optical breakout cable with a fixed length of 1 meter. One end is equipped with a QSFP28 connector, and the fan‑out side provides four independent SFP28 optical interfaces. Adopting VCSEL array and PIN photo‑detector over multi‑mode fiber, it complies with QSFP28 MSA SFF‑8665, SFP28 MSA SFF‑8402 and IEEE 802.3bj standards. It breaks out one 100G QSFP28 port into four independent 25G SFP28 channels for short‑range intra‑rack and adjacent cross‑rack interconnections in enterprise, cloud, AI and high‑performance computing data centers, eliminating copper‑caused signal attenuation and EMI interference constraints.

100G Aggregated / 4×25G Full‑Duplex Optical Transmission

Supports 100GBASE‑AOC aggregated bandwidth, breaking out into four independent 25GBASE‑AOC channels. Perfect for 100G‑to‑4×25G port expansion, leaf‑spine fabric deployment, switch‑to‑switch and switch‑to‑server interconnections.
Active Optical AOC Architecture

Integrated VCSEL transmitters and PIN receivers on both QSFP28 and SFP28 ends. Optical transmission removes distance limits of copper DAC cables. Supports Digital Diagnostic Monitoring (DDM) over I2C bus for real‑time cable health monitoring.
Light‑Weight Flexible Optical Cable Design

Much lighter and more flexible than twinax copper assemblies, complying with strict minimum bend radius requirements. Optimizes airflow and simplifies cable management for high‑density rack environments.
Hot‑Swappable QSFP28 and SFP28 Interfaces

Standard hot‑pluggable QSFP28 host connector and four SFP28 fan‑out connectors. Technicians can insert or remove the cable without powering down connected Cisco switches, routers and servers.
Robust Multi‑Mode Fiber Assembly

Multi‑mode ribbon fiber construction delivers superior electromagnetic immunity, fully resistant to EMI / RFI interference and near‑end crosstalk in dense data‑center deployments.
Standard Pull‑Tab Latch Design

Pull‑tab latches are equipped on QSFP28 and each SFP28 connector for convenient insertion and extraction from network hardware ports.
