FAQ
Does this give me 100G out of one SFP28 port?
No. It adapts the 100G QSFP28 cage so it accepts a single 25G SFP28 optic or DAC. Max throughput is 25G on that port.
Will my switch recognize it?
Most Dell, Juniper, Arista and Extreme switches support QSA adapters, but you usually must configure the port for breakout or 25G speed first. Check your switch's QSA/breakout support list.
Can I use any SFP28 optic with it?
Generally yes for standard 25G SFP28 optics and DACs, though some switches enforce coded/compatible optics. Confirm with your switch vendor's compatibility matrix.
