Description

The Cisco QSFP-4SFP10G-CU3M is a high-performance direct-attach copper (DAC) breakout cable designed for short-distance, high-speed data transmission. It features a QSFP+ connector on one end and four individual SFP+ connectors on the other, allowing a single 40G port to connect to four 10G ports. This passive copper cable is 3 meters in length, making it ideal for top-of-rack and middle-of-row deployments in data centers where minimal latency and reduced power consumption are essential. Its robust, low-profile design ensures reliable connectivity in high-density environments.

Built for compatibility with Cisco networking equipment, the QSFP-4SFP10G-CU3M supports data rates up to 10 Gbps per channel, totaling 40 Gbps aggregate bandwidth. The cable is constructed with high-quality shielding to minimize electromagnetic interference and signal loss over short distances. Each SFP+ connector includes a pull-tab latch for easy installation and removal, and the cable is fully compliant with MSA (Multi-Source Agreement) standards. This used unit has been tested for functionality and performance, making it a cost-effective solution for expanding or upgrading existing network infrastructure.
