The 40GBASE-LR4L QSFP+ Optical Transceiver Module is designed for use in 40GBASE Ethernet throughput up to 2km over single mode fiber (SMF) using a wavelength of 1310nm via duplex LC connectors. This transceiver is compliant with QSFP+ MSA and IEEE 802.3ba 40GBASE-LR4 standard. 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: The FS P/N is changed from QSFP-IR4-40G to QSFP-LR4L-40G, but the product is the same. Only the FS P/N has been changed.
