Description
F-tone Networks 400G QSFP56 DD to 8x53G SFP56 breakout Active Optical Cable offers IT professionals a cost-effective interconnect solution for merging 400G QSFP56 DD and 53G SFP56 enabled host adapters, switches and servers.

For typical applications, users can install this splitter Active Optical cable between an available QSFP56 DD port on their 400Gbps rated switch and feed up to eight upstream 50GbE-SFP56 enabled switches. Each QSFP56 DD-SFP56 splitter Active Optical cable features a single QSFP56 DD connector (QSFP DD MSA) rated for 400Gbps on one end and (8) SFP56 connectors (SFF-8431), each rated for 53Gb/s, on the other.
This module incorporates F-tone Networks Technologies proven circuit and VCSEL technology to provide reliable long life, high performance, and consistent service.
