SFP56 DAC — single-lane 50G PAM4 in copper for modern access fabrics. Often deployed as 4× SFP56 breaking out from a QSFP56 spine port; we can build that as a single paired bundle.
Form factors valid for 50G
50G ships only with SFP56.
Straight-through, breakout, or custom RFQ
50G ships straight-through only. Choose Custom (RFQ) for non-standard configurations.
Passive vs Active selection (passive default for short links).
Defaults to Passive. Active is recommended for longer runs. Custom routes to engineering review.
Mirrors Side A in straight-through; thermal top is independent
Side B mirrors Side A in straight-through. Choose a breakout architecture above to split into independent legs.
Standard lengths in meters; custom triggers engineering review
Custom lengths trigger engineering review.
Both ends share coding in straight-through
Vendor coding ensures the part number routes correctly. "Custom" triggers engineering review.
This configuration requires engineering review
Submitting will route to our engineering team for confirmation.
