Description
The Cisco QSFP-4SFP25G-CU1M is a high-performance direct-attach copper (DAC) breakout cable designed for short-distance connectivity in data centers and high-speed networking environments. Featuring a QSFP28 connector on one end and four SFP28 connectors on the other, this 1-meter passive cable enables seamless 100Gbps to 4x 25Gbps connections between compatible Cisco switches, routers, and network interface cards. Its low-power, low-latency design makes it an efficient solution for high-bandwidth applications while reducing overall infrastructure costs. The durable construction ensures reliable signal integrity and long-term performance in demanding network conditions.
This breakout cable is ideal for environments requiring high-speed interconnects without the need for additional transceivers, simplifying deployment and reducing power consumption. With robust shielding and precision-engineered connectors, it minimizes crosstalk and electromagnetic interference for stable data transmission. The passive design eliminates the need for additional power, making it an energy-efficient choice for dense networking setups. Fully compatible with Cisco networking equipment, this cable provides a cost-effective solution for expanding network capacity using pre-owned hardware.
