Sky Optics Launches The New 200G QSFP56 Direct Attach Cable

- Aug 14, 2020-

Sky Optics recently releases the new direct attache cable for data center networks. This is the 200G QSFP56 passive copper cable.


The QSFP56 passive copper cable assembly feature eight differential copper pairs,providing four data transmission channels at speeds up to 56Gbps(PAM4) per channel, and meets 200G Ethernet and InfiniBand Enhanced Data Rate(EDR) requirements. Available in a broad rang of wire gages-from 26AWG through 30AWG-this 200G copper cable assembly features low insertion loss and low cross talk.


QSFP56 uses PAM4 signals for transmission, which doubles the rate. However, there are more stringent requirements for cable insertion loss. For detailed requirements, please see High Speed Characteristics.

Designed for applications in the data center,networking and telecommunications markets that require a high speed,reliable cable assembly,this next generation product shares the same mating interface with QSFP+ form factor ,making it backward compatible with existing QSFP ports.
