• IEEE 802.3ba 40GBASE-SR4 compliance ensures full interoperability with any standards-compliant 40G optical interface, while per-lane 10GBASE-SR compliance guarantees breakout mode compatibility with 10G SFP+ interfaces over the full specification range
• Four independent parallel optical lanes operating at 10.3125 Gbps each, using VCSEL transmitters and PIN photodiode receivers, enable aggregate 40 Gbps throughput or 4x10G breakout via external MTP-to-LC fibre ribbon cable
• Hot-swappable with automatic link initialization and no host reboot required; individual lanes can be monitored independently via DOM, useful for troubleshooting multi-lane links or verifying balanced power distribution in breakout deployments
• Optimized transmit and receive characteristics prevent receiver overload when used in 4x10G breakout mode with 10GBASE-SR SFP+ modules, avoiding false DOM alarm triggers while maintaining standards compliance across the optical budget range
• OM3 and OM4 laser-optimized multimode fibre support with modal bandwidth requirements per IEEE 802.3ba; OM5 wideband multimode fibre also supported for future SWDM applications, though 850nm operation uses standard SR4 parallel transmission
• Power consumption typically under 2.5W with 3.3V single supply operation; LVCMOS control signals (ModSelL, IntL, ResetL, LPMode) provide module presence detection, interrupt notification, and low-power state management per MSA specification
