Cisco-Compatible Direct Attach Cable (DAC) Connects Network Equipment at Speeds up to 40 Gbps
Black Box QSFP+ Direct Attach Cables provide premium, error-free performance for data, storage, and high-performance computing (HPC) interconnectivity. They are 100% compatible with Cisco QSFP-H40G-CUxM=, allowing you to easily make connections amongst your Cisco switches, routers, and servers. Constructed for full compliance with the Multi-Source Agreement (MSA) and SFF-8436 industry standards, you can also make connections amongst your non-Cisco, 40-Gbps compatible networking equipment. Programmed, tested, and serialized to ensure compliance and functionality, Black Box Direct Attach Cables are the ideal solution for 40-Gbps Ethernet, fiber channel applications, and more.
Low-Cost, Low-Power Solution Ideal for In-Rack High-Density, High-Bandwidth Applications
When it comes to connecting networking equipment in high-density, high-bandwidth applications, Direct Attach Cables that operate over passive copper are the most cost-effective solution available. They are perfect for inter-rack connections of switches, routers, and servers. Further, DACs consume practically zero power, making them a much more efficient and economical connectivity solution than Active Optical Cables (AOC) and modular transceivers.
All-in-One Solution Makes for Simple Connections with Low Latency
With an all-in-one, hot-swappable cable design, Direct Attach Cables provide you with an easy-to-connect solution that doesn't require you to purchase multiple transceivers and cabling. The lack of additional connection points also means lower latency, so you can be confident of your data integrity. Hot-swappability makes upgrades and equipment replacements a breeze, minimizing downtime to your network connectivity.
