The QSFP-100G-SWDM4 is a QSFP28 transceiver designed for short-reach 100Gbps data transmission, utilizing Short-Wavelength Division Multiplexing (SWDM4) over 100m of multimode fiber at 850nm, with duplex LC connectors. It aggregates four 25Gbps lanes (each on distinct 850nm-range wavelengths) to deliver 100Gbps throughput, making it ideal for intra-data center links, such as server-to-top-of-rack (ToR) switches or switch-to-switch connections. Featuring hot-swappable functionality, integrated DDM/DOM for real-time monitoring, and compatibility with legacy multimode fiber infrastructure, it enables cost-effective 100G upgrades in existing data centers.
Share:
SWDM4 Technology: Uses four closely spaced wavelengths within the 850nm band to multiplex 4x25Gbps signals into a 100Gbps stream, allowing 100G transmission over existing OM3/OM4 multimode fiber (no need for new fiber deployment).
Short-Reach Optimization: Supports 100Gbps over 100m (OM4) or 70m (OM3) multimode fiber, targeting high-density intra-data center scenarios where short-distance, cost-efficient connectivity is critical.
Practical Compatibility: Hot-swappable QSFP28 form factor fits standard ports, integrates DDM/DOM for tracking temperature and optical power, and aligns with SWDM4 MSA standards for broad interoperability with network equipment.
