Overview of the Cisco QSFP-H40G-CU1M= 3.3 Ft Network Cable

Cisco QSFP-H40G-CU1M= is a 1-meter-long Twinaxial Network Cable designed to support high-speed data transmission in networking environments. This cable is equipped with 1X Male Quad Small Form-Factor Pluggable Plus (QSFP+) connectors, specifically designed for 40 Gigabit Ethernet Copper Networks. The Cisco is a high-quality copper network cable that serves as a reliable and efficient solution for establishing 40 Gigabit Ethernet connections. It is equipped with Quad Small Form-Factor Pluggable Plus (QSFP+) connectors, ensuring compatibility with devices supporting this interface.

Form-Factor Pluggable Technology

The term Quad Small Form-Factor Pluggable Plus or QSFP+ refers to a compact, hot-pluggable transceiver used for high-speed communication in network applications. The Quad in QSFP+ signifies that it supports four channels for data transmission, allowing for increased bandwidth.

Key Features of 40GBase-CR4 Twinaxial Copper Cable

Let's break down the key features:


The 1M in the product name indicates that the cable has a length of 1 meter. This is a critical specification as it determines the physical distance over which the cable can transmit data effectively. The "Twinaxial" nature of the cable refers to the type of construction, where two conductors are insulated and parallel to each other. This design is often chosen for its efficiency in high-frequency signal transmission.

Connector Type

The cable is equipped with 1X Male connectors. The "1X" denotes a single connection point on each end of the cable. The Male connectors are designed to plug into corresponding Female connectors, ensuring a secure and stable connection.

Network Device Support

The Cisco is explicitly designed for network devices that support QSFP+ technology. This includes a wide range of networking equipment such as switches, routers, and network interface cards that are QSFP+ compatible.

Data Transfer Rate

With 40 Gigabit Ethernet support, this cable can handle data transfer rates of up to 40 gigabits per second. This high-speed capability is crucial for modern networks that demand rapid data exchange for applications such as video streaming, cloud computing, and large-scale data transfers.

Copper Network Cable

The use of copper in the construction of the cable indicates that it is a copper-based solution rather than a fiber-optic one. Copper cables are known for their durability and cost-effectiveness, making them a preferred choice for short-distance connections within data centers and networking racks.


The Cisco cable finds applications in various networking scenarios due to its high-speed capabilities and versatile design. Some key applications include:

Data Centers

In the bustling environment of data centers, where large volumes of data are processed and transferred, Cisco plays a crucial role in providing high-speed connections between servers, switches, and other networking equipment.

High-Performance Computing

For applications that demand significant computing power, such as scientific simulations and modeling, the cable ensures that data can be swiftly exchanged between computing nodes, optimizing overall system performance.


Telecommunication networks, whether wired or wireless, require robust connectivity solutions. The Cisco facilitates high-speed data transmission, supporting the growing demands of telecommunications infrastructure.

Cloud Computing

In cloud computing environments, where resources are distributed and accessed remotely, high-speed connections are vital. This cable enables efficient communication between different components of cloud infrastructure, enhancing the overall responsiveness of cloud-based services.

Enterprise Networking

Large enterprises with extensive networks benefit from Cisco in ensuring reliable and fast communication between various departments and branches. Its compatibility with a range of networking devices makes it a versatile choice for enterprise networking.

Maximum Transmission Distance

The QSFP-H40G-CU1M= Cisco 1 Meter Twinaxial Network Cable is a 40 Gigabit Ethernet direct-attach copper (DAC) cable designed for use in high-speed data center applications. The maximum transmission distance of this cable is 1 meter or approximately 3.28 feet.

Twinaxial cables use a pair of copper wires to transmit data, which makes them ideal for use in short-distance applications within a data center environment. In addition, twin axial cables are passive and do not require any external power source or equipment for operation.

It's important to note that the maximum transmission distance of a cable can be affected by various factors, including the quality of the cable and the networking equipment being used. Therefore, it's important to consult the product specifications and guidelines to ensure that the cable is suitable for your intended application and environment.

Benefits of the Cisco QSFP-H40G-CU1M= Mini-GBIC

Understanding the advantages of the Cisco cable is essential for making informed decisions when selecting networking components. Here are some key benefits:

High-Speed Data Transfer

The primary advantage of Cisco is its ability to support data transfer rates of up to 40 gigabits per second. This high-speed capability is ideal for bandwidth-intensive applications and scenarios where rapid data exchange is critical.

Cost-Effective Solution

As a copper-based cable, the offers a cost-effective alternative to fiber-optic solutions. This is particularly beneficial for short-distance connections within data centers and networking racks where the cost of fiber optics may be prohibitive.

Versatility in Applications

The cable's compatibility with a wide range of networking devices and its suitability for various applications make it a versatile solution for different networking environments. Whether in data centers, telecommunications networks, or enterprise settings, they can adapt to diverse requirements.

Hot-Pluggable Design

The hot-pluggable nature of QSFP+ technology allows for convenient installation and maintenance. Devices can be connected or disconnected without powering down the entire system, facilitating seamless operations and reducing downtime.

Performance and Reliability

The QSFP-H40G-CU1M= is a Cisco 1-meter-long 40G QSFP+ passive copper cable designed for use in high-performance data center environments. This cable is designed to provide reliable and high-speed connectivity between networking equipment, including switches, routers, and servers.

The QSFP-H40G-CU1M= cable uses a copper design, which provides high-speed data transfer with low latency. This design allows for fast data transfer rates of up to 40 Gigabits per second (Gbps) using four 10 Gbps channels. Compared to optical cables, copper cables like the QSFP-H40G-CU1M= are generally less expensive and do not require special handling or installation considerations.

In terms of reliability, the QSFP-H40G-CU1M= cable is a passive copper cable, which means it does not require any additional power or cooling. This can make it a more reliable option compared to active copper cables, which require power to operate and may be more prone to failure.
