40G QSFP+ SR4 Optical Transceiver – 850nm MPO MMF

SVNK 40G QSFP+ SR4 Optical Transceiver – 150m MMF

The SVNK 40GBASE-SR4 QSFP+ optical transceiver is a high-performance short-reach module designed for 40 Gigabit Ethernet links over multimode fiber. It supports an aggregate data rate of 40 Gb/s using four parallel full-duplex lanes, and is fully compliant with the QSFP+ MSA and IEEE 802.3ba 40GBASE-SR4 standards, ensuring seamless interoperability with leading networking equipment.

Operating at a nominal wavelength of 850 nm, this transceiver supports transmission distances of up to 100 meters on OM3 and 150 meters on OM4 multimode fiber, making it ideal for high-density data center interconnects. It also supports breakout configurations to 4×10GBASE-SR, enabling flexible network architectures.

The module features a 12-fiber MPO/MTP male connector, hot-pluggable QSFP+ form factor, and built-in Digital Optical Monitoring (DOM) via an I²C interface, allowing real-time monitoring of operating parameters such as transmit and receive optical power, temperature, and voltage.

With VCSEL array technology, low power consumption, and enterprise-grade reliability, the SVNK 40G SR4 transceiver delivers consistent, high-speed performance for modern data center environments.
