The 100GBASE-LR Single Lambda QSFP28 Optical Transceiver Module is designed for use in 100GBASE Ethernet throughput upto 10km over single mode fiber (SMF) using a wavelength of 1330nm via duplex LC connectors. This transceiver is compliant with QSFP28 MSA, IEEE 802.3cd and 100G Lambda MSA 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 Center, 100G Ethernet, 400G to 100G breakout applications.
Note: The FS P/N is changed from Q28-LR-100G-33 to QSFP-LR-100G-33, but the product is the same. Only the FS P/N has been changed.

Got the single lambda transceivers. They are all working on the 1330nm wavelength other than 1550nm which is told to be susceptible to dispersion. They worked well indeed.
