ExaScale [EOL] vs Exablaze ExaLINK Hydra [EOL] comparison

The ExaLINK Hydra the world’s highest density Layer 1 switch. Unlike traditional network switches that operate at the data-link layer (layer 2), the ExaLINK Hydra operates at the physical network layer (layer 1). Connections through the device are made electrically through a matrix switch (see overleaf). This allows the device to tap into connections (for network monitoring), patch connections between ports (for reconfiguration) and fan-out connections from one port to many (for high speed applications), at nearly zero latency (<5ns).
