Lane Configuration: 4x 25 Gbps independent transmit and receive channels
Duplex Mode: Full-Duplex operation
Multi-Rate Capability: Supports various Ethernet data rates (e.g., 100GBASE-R, 4x25GBASE-R, 40GBASE-R, 4x10GBASE-R depending on variant and host capabilities)
Optical Interface: Varies by specific variant (e.g., MPO/MTP connector for parallel optics like SR4/PSM4, Duplex LC connector for duplex optics like LR4/CWDM4)
Reach: Varies depending on specific variant (e.g., up to 100m over Multi-Mode Fiber for SR4, up to 10km over Single-Mode Fiber for LR4)
Power Consumption: Low power dissipation, typically under 4.5W
Standards Compliance: Compliant with QSFP28 MSA (Multi-Source Agreement) and relevant IEEE 802.3 Ethernet standards (e.g., 802.3bm for 100G Ethernet, variant dependent)
