Cisco QSFP‑100G‑ACU10M Full English Product Description

Cisco QSFP‑100G‑ACU10M is an original Cisco 100GBASE‑CR4 QSFP28‑to‑QSFP28 Active Direct‑Attach Twinax Copper Cable (Active DAC) with a fixed length of 10 meters. This fully integrated pre‑terminated twinax copper assembly integrates built‑in signal conditioning, amplification and equalization chips inside QSFP28 connectors at both ends to compensate high‑speed signal attenuation for long copper transmission runs. Compliant with QSFP28 MSA SFF‑8665 and IEEE 802.3bj standards, it delivers reliable low‑latency 100‑Gigabit point‑to‑point interconnection solutions for ultra‑long‑range intra‑rack and cross‑rack links in enterprise, cloud and high‑performance computing data centers, covering distances far beyond the working limit of passive DAC copper cables.

100 Gbps Full‑Duplex Electrical Transmission

Supports 100GBASE‑CR4 Ethernet over four independent 25Gbps differential signal lanes with NRZ modulation, delivering stable bidirectional 100G throughput for leaf‑spine network fabrics, switch‑to‑switch, switch‑to‑server and high‑speed storage networking infrastructure.
Active Signal Compensation Architecture

Built‑in signal amplification and equalization circuits offset signal loss, noise and crosstalk over 10‑meter copper cable, guaranteeing excellent signal integrity for 25G per‑lane high‑speed transmission which passive twinax cables cannot achieve.
Low‑Latency Copper Transmission

Electrical copper transmission maintains lower latency compared with active optical cables (AOC), well‑suited for low‑latency computing clusters, virtualization platforms and high‑frequency trading network environments.
Hot‑Swappable QSFP28 Interface

Standard hot‑pluggable QSFP28 form factor allows technicians to install or remove the cable without powering down connected switches, routers and servers.
Multi‑Layer Shielded Twinax Construction

24 AWG multi‑layer shielded twinax copper cable suppresses EMI and RFI electromagnetic interference, reducing crosstalk risk under high‑density rack deployment conditions.
Standard Pull‑Tab Latch Design

Equipped with pull‑tab latches for convenient insertion and extraction from QSFP28 ports on network hardware.
