The 400G multimode optical transceivers incorporate 7nm DSP chip, consume less than 8.5W of power at ambient temperature, and deliver outstanding bit error rate (BER) characteristics (Pre_FEC BER less than 1E-8). Along with the 400G transceiver, Fast Photonics also offers an Open EyE compliant 400G AOC product. This AOC is one of the lowest power consuming products in the industry (below 7W per end at ambient temperature), lowest latency (86ns Roundtrip for DSP and 5ns CDR) up to 100M, and lowest cost.
