Description:
The Cisco QSFP-100G-CU2M is a passive copper twinax cable designed for short-distance, high-speed data transmission within data centers and other networking environments. It connects directly between two QSFP28 ports on networking equipment, offering a cost-effective solution for 100 Gigabit Ethernet connections over short distances.
Here are some additional details about the Cisco QSFP-100G-CU2M:
Plug-and-play: The QSFP-100G-CU2M is a hot-swappable cable, meaning it can be installed or removed from a live network without interrupting operations.
Lower power consumption: Compared to optical transceivers, DACs like the QSFP-100G-CU2M consume less power, which can help reduce energy costs.
Cost-effective: DACs are generally less expensive than optical transceivers, making them a good choice for short-distance applications where cost is a major concern.
Limitations:
Reach: The maximum reach of the QSFP-100G-CU2M is limited to 2 meters due to signal degradation over longer copper cables.
EMI susceptibility: Copper cables are more susceptible to electromagnetic interference (EMI) compared to fiber optic cables.
Applications:
High-performance computing clusters
Top-of-rack switching
Storage area networks (SANs)
Short-distance data center interconnects
