Rigorous Testing

Rigorous Testing

Every TenFour Optics transceiver — from a 1G SFP to an 800G coherent module — runs through the same 15-point test process before it ships. We validate each unit against a live test network of 150+ real OEM platforms, and that network keeps growing.

The standard doesn't flex with the part number. A 10G LR, a 100G LR4, a 400G client optic, and a 400G or 800G coherent module — 400ZR, 400ZR+, 800G ZR — all face the same question before they leave: does it perform on your network and not just on a datasheet.

For coherent optics especially, that means the hard tests get run, not assumed — dispersion tolerance, SNR, eye-diagram analysis, and bit-error-rate. It's the commitment behind GreenLights4Life®.
