IBM 45W9396 QSFP+ to QSFP+ 40Gb/s Cable (1.1m) — direct-attach passive copper cable designed for high-speed interconnect between switches, routers, and adapters. Supports 40 Gigabit Ethernet at distances up to 1.1 meters (3.6 feet), ideal for top-of-rack and in-rack deployments where latency-sensitive throughput is critical. QSFP+ connectors on both ends ensure compatibility with IBM, Cisco, Arista, Mellanox, and other major enterprise switch and NIC platforms. Typical applications include data center fabric, high-performance computing clusters, and storage area network backbone links. Low power consumption and passive design eliminate external power requirements. Tested and guaranteed, available via quote.
