800G OSFP 2FR4 Optical Transceiver – 2km LC SMF

SVNK 800G OSFP 2×FR4 Optical Transceiver – 2km SMF

The SVNK 800G OSFP 2×FR4 optical transceiver is a high-performance module engineered for 800 Gigabit Ethernet (800GbE) links over single-mode fiber (SMF) with a reach of up to 2 kilometers. Designed in the OSFP form factor, this transceiver is optimized for next-generation data centers, hyperscale cloud networks, AI fabrics, and high-performance computing environments.

This module features 8 independent electrical input/output lanes, each operating at up to 106.25 Gb/s using PAM4 modulation, delivering an aggregate throughput of up to 800G. It integrates two FR4 optical engines, each utilizing four CWDM wavelengths on the ITU-T G.694.2 grid near 1300 nm, enabling efficient wavelength multiplexing and high-density long-reach connectivity.

The electrical interface complies with IEEE 802.3ck 800GAUI-8 and OSFP MSA specifications, ensuring seamless interoperability with leading switch and router platforms. Built-in Digital Optical Monitoring (DOM) via the I²C interface provides real-time visibility into operating parameters such as temperature, voltage, and optical power levels.

With its hot-pluggable design, low power consumption, and dual LC optical connectors, the SVNK 800G OSFP 2×FR4 transceiver enables rapid deployment, simplified cabling, and scalable 800G network upgrades.
