200G QSFP56 LR4 Optical Transceiver – 10km LC SMF

SVNK 200G QSFP56 LR4 Optical Transceiver (10 km, SMF)

The SVNK 200G QSFP56 LR4 Optical Transceiver is a high-performance optical module engineered for 200 Gigabit Ethernet transmission over SMF-28 single-mode fiber. Fully compliant with the QSFP MSA and IEEE 802.3bs 200GBASE-LR4 standards, the module is designed to meet the performance, reliability, and scalability requirements of next-generation data centers, cloud networks, and enterprise backbones.

The transceiver converts four 53.125 Gb/s electrical lanes into four LAN-WDM optical wavelengths, which are multiplexed into a single optical signal to deliver an aggregate data rate of 212.5 Gb/s. On the receive side, the signal is demultiplexed and converted back into high-speed electrical outputs. This WDM-based LR4 architecture enables efficient long-reach transmission of up to 10 km over single-mode fiber.

SVNK 200G LR4 integrates a built-in PAM4 DSP, cooled EA-DFB laser transmitters, and high-sensitivity PIN ROSA receivers, providing excellent optical stability, superior dispersion tolerance, and robust long-distance performance. Housed in a compact, hot-pluggable QSFP56 form factor, the module supports high port density and simplified network upgrades.
