Choosing 400G optics: SR, DR, FR and LR, and what each one costs you in fibre
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 […]
Émetteurs-récepteurs optiques 400G : Performances à haut débit et compatibilité totale avec les OEM
As AI, cloud, and video workloads explode, 40G and 100G links quickly become the bottleneck. Moving to 400G multiplies throughput per port, reduces the number of links to manage, and lowers cost per bit—without redesigning your network from scratch. This guide explains 400G optical transceivers in plain English and shows how Carritech Optics helps you […]
