800G SR8 Optical Transceiver – 850nm MPO MMF

SVNK 800GBASE-SR8 QSFP-DD Optical Transceiver – 100 m MMF

The SVNK 800GBASE-SR8 QSFP-DD optical transceiver is a next-generation, ultra-high-speed module engineered for 800 Gigabit Ethernet short-reach applications over multimode fiber (MMF). Operating at a nominal wavelength of 850 nm, this transceiver is designed to support ultra-dense data center, cloud, AI, and HPC interconnects requiring massive bandwidth, low latency, and high reliability.

The module integrates eight independent high-speed optical lanes, each operating at 106.25 Gb/s using PAM4 modulation, delivering an aggregate throughput of up to 800G. It utilizes an advanced VCSEL laser array and PIN photodiode receiver array, enabling stable, low-power, and high-signal-integrity transmission over OM4 and OM5 multimode fiber.

Compliant with QSFP-DD MSA, CMIS, and IEEE 802.3 SR8 architectures, the SVNK 800GBASE-SR8 ensures seamless interoperability with next-generation 800G switches, routers, and GPU/AI fabrics. The module features an MPO-16 high-density optical interface, making it ideal for spine-leaf architectures and large-scale data center deployments.

With hot-pluggable capability, integrated digital diagnostics monitoring (DDM), and optimized power efficiency, this transceiver delivers a future-proof solution for high-performance short-reach 800G optical networks.
