The 40GBASE-LR QSFP+ 40G module is designed for use in 40GBASE Ethernet throughput up to 10km over single mode fiber (SMF) using a wavelength of 1310nm via a MTP/MPO-12 connector. This transceiver is compliant with QSFP+ MSA. Digital diagnostics functions are also available via the I2C interface, as specified by the QSFP+ 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 and distribution layer applications.
Note: If this transceiver needs to be used to break out one 40G signal into 4x 10G signals, the interface of the device is required to support the breakout feature.
