ExaLINK Fusion FastMux


With latency as low as 39ns, the FastMux is twice as fast as previous generation multiplexers.

The ExaLINK Fusion is available with FastMux, the lowest-latency multiplexer on the market. FastMux enables aggregation of many 10Gb/s Ethernet connections into a single upstream port, with almost identical latency for all ports.

The performance of FastMux has been verified using ExaNIC-HPT, Exablaze’s High Precision Timestamp capture device which measures the time between network events to 250 picoseconds resolution.

ExaLINK Fusion FastMux ships with a Performance Verification Report which shows:

  • Performance results (minimum 38ns, median 42ns, maximum 48ns)
  • Configuration and how the measurements were taken
  • Latency distribution of all ports.

The FastMux is built on the ExaLINK Fusion Layer 1 matrix switch platform. All 48 ports on the ExaLINK Fusion, including FastMux ports, are enabled to perform layer 1 switching. This provides support for features, such as tapping for logging, patching for failover, and packet counters and signal quality statistics for monitoring.
