Cisco QSFP‑100G‑ACU7M Full English Product Description

Cisco QSFP‑100G‑ACU7M is an original Cisco 100GBASE‑CR4 QSFP28‑to‑QSFP28 Active Direct‑Attach Twinax Copper Cable (Active DAC) with a fixed length of 7 meters. This fully integrated pre‑terminated twinax copper assembly is fitted with built‑in signal conditioning chips inside QSFP28 connectors at both ends to compensate high‑speed signal attenuation over long copper cable 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 long‑range intra‑rack and cross‑rack links in enterprise, cloud and high‑performance computing data centers, beyond the reach of passive DAC 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 and crosstalk on long‑reach copper cables, ensuring excellent signal integrity at 25G per lane for 7‑meter copper transmission that passive twinax cables cannot achieve.
Low‑Latency Copper Transmission

Electrical copper transmission maintains lower latency compared with active optical cables (AOC), suitable 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

26 AWG multi‑layer shielded twinax copper cable suppresses EMI and RFI electromagnetic interference, reducing crosstalk in high‑density rack deployment environments.
Standard Pull‑Tab Latch Design

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