100G QSFP28 SR4 Optical Transceiver – 850nm MPO MMF

SVNK 100G QSFP28 SR4 Optical Transceiver (100 m, MMF)

The SVNK 100G QSFP28 SR4 Optical Transceiver is a high-performance multimode optical module designed for 100 Gigabit Ethernet (100GbE) short-reach applications. It supports transmission distances of up to 70 meters over OM3 and 100 meters over OM4 multimode fiber, making it ideal for high-density data center and enterprise network deployments.

The module is fully compliant with the QSFP28 MSA and IEEE 802.3bm 100GBASE-SR4 specifications. It integrates four parallel electrical and optical lanes in each direction, each operating at up to 25.78125 Gb/s, to deliver an aggregate throughput of 100 Gb/s.

The electrical interface uses a 38-contact edge connector, while the optical interface employs a 12-fiber MPO/MTP connector, enabling compact, high-density connectivity. The transmitter incorporates a 4-channel 850 nm VCSEL array, and the receiver integrates high-sensitivity PIN photodiodes, ensuring excellent signal integrity, low bit-error rates, and stable optical performance.

With built-in Clock and Data Recovery (CDR) on both transmit and receive paths (with optional bypass), the module provides enhanced jitter tolerance and improved system interoperability.

Housed in a compact, hot-pluggable QSFP28 form factor, the SVNK 100G SR4 transceiver is optimized for low power consumption, thermal efficiency, and seamless integration into modern switching and server platforms.
