Choosing 400G optics looks like a distance problem. You know how far the link has to go, you pick the part that reaches that far, and you order it. It is not a distance problem. It is a fibre problem wearing a distance problem’s clothes — because the four letters on the end of the […]
The real TCO of 400G: power, price and compatibility

The real 400G transceiver cost is not the price on the optic, and every 400G business case starts the same way. Someone divides the price of a 400G optic by the price of a 100G optic, sees a number that looks bad, and the conversation stops there. It is the wrong sum. Not because 400G […]
Transceptores ópticos 400G: Desempenho de alta velocidade com compatibilidade total com OEM
