FS.COM 100G QSFP28 to 4x25G SFP28 Passive Direct Attach Copper Breakout Cables leverage parallel technology standard defined by IEEE. This technology uses 4 lanes in each direction that must be supported by the switch or router. A fiber, which is a passive medium and has no concept of the signal speed, connects one 100G port (carrying four 25G lanes) to four 25G ports.2017年5月08日にS***oより発表された
