• IEEE 802.3ba 40GBASE-SR4 compliance guarantees physical layer interoperability for native 40G Ethernet, while each individual 10G lane adheres to IEEE 10GBASE-SR specifications for breakout compatibility
• Four independent parallel transmit and receive lanes operating at 10.3125 GBd each, aggregating to 40Gbps throughput over 12-fiber MPO ribbon cable
• Extended reach CSR4 variant doubles the distance capability of standard SR4 optics, enabling 300m on OM3 and 400m on OM4/OM5 laser-optimized multimode fiber
• Supports both native 40G aggregation with MPO/MTP patch cables and 4x10G breakout mode using parallel-to-duplex breakout cables for connection to four separate 10GBASE-SR ports
• Digital diagnostics monitor real-time operating parameters including temperature, supply voltage, transmit bias current, transmit power, and receive power per QSFP+ MSA SFF-8436 specification
• Hot-swappable module with commercial temperature rating (0 to 70 degrees Celsius) suitable for data centre spine-leaf, aggregation layer, and high-performance computing interconnects
• VCSEL transmitter technology at 850nm wavelength optimized for multimode fiber propagation, minimizing dispersion and maximizing link margin across OM3 and OM4 fiber types
