400G OSFP DR4 Optical Transceiver – 500m MPO SMF

SVNK 400G OSFP DR4 Optical Transceiver (500 m, SMF)

The SVNK 400G OSFP DR4 Optical Transceiver is a high-performance module engineered to support 400 Gigabit Ethernet (400GbE) links over single-mode fiber (SMF) with a reach of up to 500 meters. Designed for next-generation data centers, cloud infrastructure, and high-performance computing environments, this transceiver delivers ultra-high-speed, low-latency, and scalable optical connectivity.

Fully aligned with IEEE 802.3bs 400GBASE-DR4 specifications, the module converts high-speed electrical signals into four parallel optical channels, each operating at 100 Gb/s PAM4, using advanced 1310 nm EML-based transmitters. On the electrical side, the module supports a 400GAUI-8 interface (8 × 50G PAM4) with integrated retiming and signal conditioning to ensure excellent signal integrity and robust system performance.

The transceiver integrates a high-density MPO-12 optical interface, optimized for parallel SMF connectivity and high port-count switching platforms. Housed in a compact, hot-pluggable OSFP form factor, the module supports high power efficiency, thermal stability, and simplified deployment in dense environments.

Built-in Digital Optical Monitoring (DOM/DDM) via an I²C management interface enables real-time performance tracking and proactive network management.
