Description
The Cisco QSFP-4SFP25G-CU5M is a passive copper transceiver module designed for short-distance data transmission applications. It features a QSFP28 connector on one end and four SFP28 connectors on the other end. This allows you to connect a 100Gbps QSFP28 port on a switch or router to four 25Gbps SFP28 ports on other devices.
The module utilizes passive copper technology, which makes it a cost-effective solution for interconnecting equipment within a close range, such as within data centers or telecom rooms. It is a low-power solution as it does not require any external power source.
