Cisco QSFP-4SFP25G-CU2M

The Cisco QSFP-4SFP25G-CU2M is a high-speed direct-attach copper cable designed for use in data centers and high-performance computing environments. It is a 2-meter long cable that features a QSFP28 (Quad Small Form-Factor Pluggable 28) connector on one end and four SFP28 (Small Form-Factor Pluggable 28) connectors on the other end. This cable is used to connect network switches, routers, and servers that support QSFP28 and SFP28 interfaces. It provides a cost-effective solution for short-reach interconnects within a rack or between adjacent racks, offering a data transfer rate of up to 25 Gbps per lane, resulting in a total bandwidth of 100 Gbps. The QSFP-4SFP25G-CU2M cable is hot-swappable, meaning it can be plugged or unplugged without disrupting the operation of the connected devices. It is commonly used in high-density data center environments where space and power consumption are critical factors.
