800G OSFP SR8 Optical Transceiver – 850nm MPO MMF

SVNK 800G OSFP SR8 Optical Transceiver – 100m MMF (InfiniBand NDR & Ethernet)

The SVNK 800G OSFP SR8 optical transceiver is a next-generation, high-performance module engineered to support 800 Gigabit Ethernet and InfiniBand NDR links over multimode fiber (MMF) with a maximum reach of up to 100 meters on OM4. Designed in the OSFP form factor, this module is optimized for hyperscale data centers, AI fabrics, and high-performance computing (HPC) environments requiring ultra-high bandwidth, low latency, and short-reach optical interconnects.

The transceiver integrates 8 independent electrical input/output lanes, each operating at 106.25 Gb/s using PAM4 modulation, delivering an aggregate throughput of up to 800G. It employs advanced 850 nm VCSEL-based optics with parallel multimode architecture, ensuring excellent signal integrity, low power consumption, and reliable high-speed transmission.

The electrical interface complies with IEEE 802.3ck 800GAUI-8 and OSFP MSA specifications, providing broad interoperability with next-generation switches, routers, and accelerator platforms. Built-in Digital Diagnostic Monitoring (DDM) via the I²C interface enables real-time access to module operating parameters such as temperature, voltage, and optical power.

With its hot-pluggable design, dual MPO-12 APC connectors, and optimized thermal efficiency, the SVNK 800G OSFP SR8 transceiver enables rapid deployment of scalable 800G infrastructures.
