In the world of networking and data transmission, the QSFP-H40G-ACU10M is a critical component that plays a crucial role in ensuring high-speed data transfer. This 10-meter Direct-Attach Copper (DAC) Active Twinaxial Network Cable, often referred to simply as the QSFP-H40G-ACU10M cable, is designed to facilitate the rapid exchange of data between devices in a network. In this comprehensive guide, we will delve into the details of this cable, exploring its key features, applications, benefits, and how it contributes to efficient data transmission.
What is the QSFP-H40G-ACU10M CableThe QSFP-H40G-ACU10M is a specific type of network cable designed to connect various networking equipment, such as switches, routers, and servers, in high-performance data centers and enterprise environments. Its name breaks down as follows:
QSFP: This stands for Quad Small Form-factor Pluggable, which refers to the type of connector used in the cable. QSFP connectors are known for their compact size and high data transmission capabilities.
H40G: This part of the name indicates that the cable is designed for 40 Gigabit Ethernet (40GbE) applications. In other words, it's capable of transferring data at a speed of 40 gigabits per second (Gbps).
ACU10M: ACU stands for Active Copper Cable, implying that this cable is an active twinaxial copper cable. The "10M" specifies the cable's length, which is 10 meters.
40GBASE-CR4: This is another way of indicating that the cable is designed for 40GbE applications. The "CR4" refers to the electrical interface, which is used for 40GbE over copper connections.
Now that we understand the name and its components, let's dive deeper into the various aspects of this cable.
Key Features of the QSFP-H40G-ACU10M CableThe QSFP-H40G-ACU10M cable comes with several key features that make it a popular choice for high-speed networking applications:
High Data Transfer Rate: As mentioned earlier, this cable is designed for 40GbE applications, which means it can transmit data at an impressive rate of 40 gigabits per second. This high data transfer rate is essential for data centers and networks that require rapid data exchange.
Active Twinaxial Cable: The "ACU" in its name indicates that this cable is an active twinaxial cable. Active cables have built-in signal processing electronics that help maintain signal integrity over longer distances. Twinaxial cables consist of two inner conductors surrounded by insulation and a shield. This design minimizes signal interference and enhances data transmission quality.
10-Meter Length: The 10-meter length of this cable provides flexibility in network design and allows for efficient data transmission over moderate distances. It's suitable for connecting devices within the same rack or adjacent racks in a data center.
QSFP Connector: The QSFP connector is known for its compact size, which helps save space in networking equipment. Additionally, it's hot-swappable, meaning it can be plugged and unplugged without powering down the connected devices.
40GBASE-CR4 Compatibility: The cable is specifically designed for 40GBASE-CR4 applications. 40GBASE-CR4 is a standard for 40GbE over copper connections, and this cable meets its requirements for reliable data transmission.
Active Electronics: The active electronics in this cable help compensate for signal loss, ensuring that the data signal remains strong and clear even over longer distances. This is particularly important in data centers where devices may be located some distance apart.
