QSFP-H40G-CU5M Overview
The QSFP-H40G-CU5M is a 40 Gigabit Ethernet passive copper cable that provides high-speed 40G connectivity over short distances. It utilizes four lanes of 10.3 Gbps signaling per lane to achieve an aggregate throughput of 40 Gbps. This direct attach copper cable offers a cost-effective means of connecting 40G QSFP+ ports within racks in data centers, eliminating the need for active transceivers and fiber cables.
With its 5-meter cable length, the QSFP-H40G-CU5M allows flexibility in equipment layouts and connections between devices across adjacent racks. The passive design makes it a simple and power-efficient solution.
