The 10-Gbit Ethernet ecosystem is rapidly maturing, with multiple vendors offering network interface adapters with offload capabilities and high-density low-latency switches. For many high-speed applications, 10 GbE is becoming an increasingly attractive option to traditional Fiber Channel and InfiniBand interconnects. As the market matures, several choices have evolved for physical layer connection and, as with the 1-Gbit generation, both optical and copper are options. Each physical layer alternative has advantages in terms of distance, cost, latency, and physical media, which must be weighed together in relation to the system's application.
