• IEEE 802.3cd 100GBASE-DR compliance ensures standards-based interoperability with multi-vendor 100G single-mode infrastructure and forward compatibility with 400G-DR4 systems via breakout cables
• Single-lambda PAM4 architecture operates at 53.125 GBaud over 1310nm band, using onboard DSP gearbox to convert four 25Gbps NRZ electrical lanes (CAUI-4 interface) into one 100Gbps PAM4 optical lane, reducing fibre count by 75% compared to parallel SR4 or PSM4 topologies
• Host-based FEC (Reed Solomon RS(528,514) per IEEE 802.3bj) is required to correct pre-FEC bit error ratio and ensure reliable system operation at PAM4 signalling rates
• EML transmitter and PIN photodiode receiver with integrated CDR circuitry maintain signal integrity across the 3 dB optical link budget, suitable for typical data centre leaf-spine distances well under 500m
• Hot-swappable QSFP28 MSA form factor with duplex LC/UPC connector simplifies deployment in dense 100G switch fabrics, reducing cabling complexity and fibre management overhead
• DDM functionality accessible via I2C interface exposes real-time parameters including transmit and receive optical power, module temperature, laser bias current, and supply voltage for proactive link health monitoring
• RoHS compliant with 0 to 70°C operating case temperature range and 4.5W maximum power dissipation, designed for controlled data centre environments with appropriate thermal management
