Description:
The Cisco QSFP-100G-CU3M is a passive twinax copper cable designed for short-distance, high-speed data transmission between devices with QSFP28 ports. It is a cost-effective and low-power solution for connecting switches, routers, and servers within a rack or across adjacent racks.
Here are some key points about the Cisco QSFP-100G-CU3M:
Passive DAC: This cable does not require any external power source, making it energy-efficient.
Hot-swappable: The cable can be inserted and removed from a live network without interrupting traffic.
Limited reach: DACs are typically limited to short distances, like 3 meters in this case, due to signal degradation over longer copper cables.
Cost-effective: DACs are generally less expensive than optical transceivers for short-distance applications.
Applications:
Data center inter-rack connections
High-performance computing clusters
Enterprise core and distribution networks
Short-reach connections between network devices
