The QSFP-100G-SR4 QSFP28 Optical Transceiver Module is designed for use in 100GBASE Ethernet throughput up to 70m over OM3 and 100m over OM4 multimode fiber (MMF) using a wavelength of 850nm via a MTP/MPO-12 connector. The module also supports breakout to 4x 25GBASE-SR SFP28. The transceiver is compliant with QSFP28 MSA, SFF-8636, IEEE 802.3bm, and CAUI-4 standards. Digital diagnostics are provided via the I2C interface for real-time monitoring.

It is suitable to be used in various applications, such as data centres, high-performance computing networks, enterprise core and distribution layer applications.
