AddOn offers high-speed fiber optic transceivers optimized for latency-sensitive environments such as high-frequency trading and high-performance compute networks. By reducing or eliminating forward error correction (FEC), which can introduce up to 100 nanoseconds of latency, these solutions help maximize throughput and enable faster transaction processing.
The low latency QSFP-DD 200G SR8 transceiver supports 8x25G Ethernet up to 50 meters over OM4 without FEC and 8x10G Ethernet up to 400 meters over OM4. Designed for ultra-low latency performance, it enables reduced or no FEC operation to minimize processing delays in high-performance environments.
For higher-speed and extended-reach applications, QSFP28 CLR4 enables low latency 100G connectivity over single-mode fiber, while QSFP-DD 200G PSM8 supports CDR bypass to aggregate 25G and 10G traffic into a QSFP-DD port. QSFP28 SR4 and PSM4 transceivers support operation without host FEC up to 40 meters, and SFP28 25G SR and LR solutions extend low latency performance across short- and long-range deployments.
