BLC SFP+ 3M 10GBE Copper Direct attach Cable

The HPE 487655-B21 is a high-performance **3-meter SFP+ 10 Gigabit Ethernet Direct Attach Copper (DAC) cable** designed for short-distance, high-speed network connections. This cable provides a cost-effective, low-latency, and energy-efficient solution for connecting servers and switches within a single rack or between adjacent racks. It is an essential component for building a reliable and high-throughput network infrastructure in a data center.

The cable is a passive twin-axial design, which means it requires no additional power and is an integrated solution that combines the cable and transceivers, simplifying deployment and reducing points of failure compared to separate components.

Features :

This copper Direct attach Cable is engineered for seamless, plug-and-play operation. Its **SFP+ connectors** are designed for a secure fit into 10GbE SFP+ ports on switches and servers. The **3-meter length** is ideal for short-reach applications, such as connecting a top-of-rack switch to multiple servers within the same rack. The **487655-B21** is a genuine HPE component, ensuring full compatibility and optimal performance with HPE network hardware. Its robust construction provides a durable and reliable connection for mission-critical applications.

Advanced Options :

Using a Direct attach Cable like this is a smart choice for optimizing your data center network. It offers a more economical alternative to fiber optic transceiver and patch cable combinations, reducing both hardware costs and power consumption. The low-latency nature of copper Direct attach Cable is particularly beneficial for high-frequency trading, high-performance computing, and other applications where every millisecond counts, providing a superior performance solution for short-distance links.
