The QSFP56 passive copper cable assembly is available with eight differential copper pairs, providing 4 data transmission channels with speeds up to 56 Gbps per channel, meeting 200G Ethernet standards. It is available in a range of wire gauges from 26 to 30 AWG and is designed to minimize insertion loss and crosstalk.

Using PAM4 signaling, QSFP56 doubles the data rate but imposes stricter requirements for insertion loss.

This next-generation cable assembly is designed for data centers, networking, and telecommunications applications. it offers high-speed and dependable connections. It also shares the same mating interface as the QSFP+ form factor, making it backward compatible with existing QSFP ports.
