The 100GBASE-SR4 QSFP28 Optical Transceiver Module is designed for use in 100GBASE Ethernet throughput up to 100m over OM4 multimode fiber (MMF) using a wavelength of 850nm via an MTP/MPO-12 connector. This transceiver is compliant with IEEE 802.3bm 100GBASE-SR4 and CAUI-4 standard. Digital diagnostics functions are also available via the I2C interface, as specified by the QSFP28 MSA, to allow access to real-time operating parameters. With these features, this easy to install, hot swappable transceiver is suitable to be used in various applications, such as data centers, high-performance computing networks, enterprise core, distribution layer and telecom applications.
Note: The FS P/N is changed from QSFP28-ISR4-100G to QSFP-SR4-100G-I, but the product is the same. Only the FS P/N has been changed.

I have put the two transceivers to work, and they are working well. I’m using these in a personal environment rather than professional, but I will likely be buying more in the near future.
