Product overview for the Cisco QSFP-H40G-ACU10M=

In today's digital age, high-speed data transmission is crucial for businesses and individuals alike. One technology that plays a pivotal role in achieving fast and reliable data transfer is the QSFP-H40G-ACU10M 40GBASE-CR4 10 Meter Direct-Attach Copper (DAC) Active Twinaxial Network Cable. This article delves into the details of this impressive piece of networking equipment, explaining its features, benefits, and how it works.

What is a QSFP-H40G-ACU10M Cable

A QSFP-H40G-ACU10M cable is a type of high-speed data transmission cable used in networking and data center environments. The name itself is packed with information:

QSFP: This stands for "Quad Small Form-factor Pluggable." It's a widely used interface for high-speed data communication.

H40G: This signifies that the cable is designed for 40 gigabit per second (Gbps) data transfer rates. In other words, it's capable of transmitting data at a blazingly fast speed.

ACU10M: This part of the name tells us about the cable's length. In this case, it's 10 meters, which is a substantial length for networking purposes.

Direct-Attach Copper (DAC) Active Twinaxial Network Cable: This is a mouthful, but it essentially means that the cable is a type of copper-based cable, is active (meaning it has electronic components to boost signal quality), and utilizes twinaxial technology for data transmission.

Now that we understand the name, let's break down the key components and functionalities of the QSFP-H40G-ACU10M cable.

Key Components and Features

Quad Small Form-factor Pluggable (QSFP)

The QSFP interface is a compact, hot-pluggable transceiver used for high-speed data communication. It is widely adopted in data centers and networking equipment due to its small form factor and ability to support various data rates, including 40Gbps, which is the focus of the QSFP-H40G-ACU10M cable.


The "40GBASE-CR4" specification indicates the cable's compatibility with 40 Gigabit Ethernet (40GbE) communication over a copper medium. This standard is well-suited for short-distance data transmission within data centers and high-performance computing environments.

10 Meter Length

The cable's 10-meter length makes it suitable for connecting devices that are relatively distant from each other within a data center or network infrastructure. This length provides flexibility in cable routing and placement.

Direct-Attach Copper (DAC) Technology

DAC cables are known for their cost-effectiveness and simplicity. These cables consist of copper conductors with specialized connectors on each end. In the case of the QSFP-H40G-ACU10M, it uses copper for signal transmission, which is a reliable and widely adopted medium for networking.

Active Twinaxial Technology

The term "active" in the cable's name suggests that it incorporates active components to enhance signal quality and reach. Active cables are capable of longer-distance data transmission compared to passive cables, making them suitable for various networking scenarios.

Now that we have a clear understanding of the key components and features of the QSFP-H40G-ACU10M cable, let's explore its benefits and use cases.

Benefits of QSFP-H40G-ACU10M Cable

High-Speed Data Transfer

The primary advantage of the QSFP-H40G-ACU10M cable is its ability to transmit data at a remarkable speed of 40Gbps. This high bandwidth is essential for applications that demand rapid data transfer, such as large file transfers, video streaming, and data backup.

Cost-Effective Solution

DAC cables are known for their cost-effectiveness. They provide a reliable and affordable option for high-speed connectivity within data centers and network infrastructures. This cost efficiency is particularly valuable for organizations looking to optimize their networking budgets.

Plug-and-Play Installation

QSFP-H40G-ACU10M cables are designed for easy installation. They feature connectors that can be plugged in and removed without the need for special tools or expertise. This plug-and-play nature simplifies cable management and reduces downtime during network maintenance.

Flexible Cable Length

With a 10-meter length, this cable offers flexibility in network design and layout. It can bridge the gap between devices situated at a considerable distance from each other, allowing network architects to plan and implement efficient data center configurations.

Reliable Copper-Based Transmission

Copper-based cables, like the QSFP-H40G-ACU10M, are known for their reliability and resistance to electromagnetic interference (EMI). This makes them suitable for use in challenging environments where signal integrity is crucial.

Active Twinaxial Technology

The active components in the cable enhance signal quality and reach, enabling data transmission over longer distances compared to passive cables. This is particularly beneficial in scenarios where devices are not in close proximity.

Now that we've explored the benefits of the QSFP-H40G-ACU10M cable, let's delve into its applications and use cases.
