200G QSFP56 FR4 Optical Transceiver – 2km LC SMF

SVNK QSFP-DD 200GBASE-FR4 Optical Transceiver (2 km, SMF)

The SVNK QSFP-DD 200GBASE-FR4 Optical Transceiver is a high-performance optical module engineered for 200 Gigabit Ethernet transmission over single-mode fiber (SMF). Designed for next-generation data center, cloud, and enterprise networks, the module enables high-speed, low-latency connectivity with excellent signal integrity and power efficiency.

The transceiver converts four 53.125 Gb/s electrical lanes into four CWDM optical wavelengths, which are multiplexed into a single optical signal to support an aggregate data rate of 212.5 Gb/s. On the receive side, the incoming optical signal is demultiplexed back into four optical channels and converted into high-speed electrical outputs. This CWDM-based FR4 architecture enables efficient fiber utilization while supporting link distances of up to 2 km over SMF.

SVNK 200G FR4 integrates a built-in PAM4 DSP, uncooled DML-based TOSA, and high-sensitivity PIN ROSA, delivering reliable high-speed transmission with low bit-error rates and excellent thermal stability. The compact, hot-pluggable QSFP-DD form factor allows high port density and seamless deployment in modern switches and routers.
