The HP 487655-B21 is a 10 Gigabit Ethernet (10GbE) SFP+ to SFP+ 3-meter Direct Attach Copper (DAC) Cable, designed to provide high-speed, reliable connectivity between networking equipment. This cable is an ideal solution for connecting HP ProLiant servers to switches, routers, or network interfaces that support 10GbE and have SFP+ ports. The DAC cable is a cost-effective alternative to fiber optic cables, offering the advantage of lower latency and reduced power consumption, which is crucial in high-performance computing environments. The 3-meter length provides flexibility in connecting devices at a distance that is typical within rack configurations in data centers. Its plug-and-play nature simplifies the installation process, allowing immediate improvement of network throughput and bandwidth without the need for transceivers. Crafted with durability in mind, the HP 487655-B21 is built to withstand the rigors of a demanding data center environment, ensuring a reliable connection that maintains the integrity and security of data transmission. This cable is an essential component for network architects and IT professionals who demand high-speed, low-latency connections for their critical network infrastructure.
