200G QSFP56 SR4 Optical Transceiver – 850nm MPO MMF

SVNK 200G QSFP56 SR4 Optical Transceiver (MMF, up to 100 m)

The SVNK 200G QSFP56 SR4 Optical Transceiver is a high-performance multimode optical module engineered for 200 Gigabit Ethernet short-reach applications. Designed for deployment over OM3/OM4/OM5 multimode fiber, it fully complies with the QSFP MSA and IEEE 802.3cd 200GBASE-SR4 specifications, making it ideal for next-generation data centers, cloud infrastructure, and high-density enterprise networks.

The module converts four 53.125 Gb/s PAM4 electrical lanes into four parallel optical channels, delivering an aggregate throughput of up to 212.5 Gb/s. Integrated PAM4 DSP signal conditioning ensures excellent eye performance, low bit-error rates, and stable operation in high-port-count environments.

The optical engine incorporates an uncooled 4-channel 850 nm VCSEL array and a high-sensitivity PIN photodiode receiver array, optimized for short-reach multimode transmission. The transceiver supports link distances of up to 70 m over OM4 and 100 m over OM5 multimode fiber and utilizes a high-density MPO-12 connector for parallel optical connectivity.

Housed in a compact, hot-pluggable QSFP56 form factor, the module supports advanced monitoring and management through a CMIS v4.0 compliant I²C interface.
