800G QSFP-DD 2LR4 Optical Transceiver – 10km LC SMF

SVNK 800GBASE-2LR4 QSFP-DD800 Optical Transceiver – 10 km SMF

The SVNK 800GBASE-2LR4 QSFP-DD800 optical transceiver is a next-generation, ultra-high-speed module engineered to support 800 Gigabit Ethernet links over single-mode fiber (SMF) with transmission distances of up to 10 km. Designed in the compact QSFP-DD Type 2A form factor, this transceiver is ideal for hyperscale data centers, cloud networks, and enterprise backbones requiring long-reach 800G connectivity.

The module integrates 8 independent high-speed electrical lanes, each operating at 106.25 Gb/s using PAM4 modulation, delivering an aggregate throughput of up to 800G. It adopts an advanced 2×LR4 optical architecture, utilizing CWDM wavelengths in the 1310 nm window in accordance with the 100G Lambda MSA, enabling efficient wavelength multiplexing for extended-reach optical transmission.

Compliant with IEEE 802.3ck, QSFP-DD MSA, and CMIS Rev. 5.0, the SVNK 800GBASE-2LR4 ensures broad interoperability with next-generation switches, routers, and optical platforms. Integrated Digital Diagnostics Monitoring (DDM/DOM) via the I²C interface provides real-time visibility into module operating conditions, enhancing reliability, performance management, and preventive maintenance.

With hot-pluggable support, dual LC connectors, low power dissipation, and high-density compatibility, this transceiver is optimized for scalable 800G deployments, including breakout applications of 2×400G LR4.
