Description:
The Cisco QSFP-4SFP10G-CU1M transceiver module is a passive copper cable assembly designed for short-distance, high-bandwidth connections within a rack or between adjacent racks. It features a QSFP+ connector on one end that plugs into a 40 Gigabit Ethernet (GbE) port on a Cisco switch and four SFP+ connectors on the other end that connect to four 10 GbE ports on other network devices.
This passive copper cable offers a cost-effective solution for interconnecting devices at close proximity. It leverages existing copper cabling infrastructure and avoids the need for expensive optical transceivers. However, the reach is limited to 1 meter due to signal degradation over copper.
