Audited Supplier The QSFP28 module provides 100GBase-LR4 throughput up to 10km over a standard pair of single mode fiber (SMF) with duplex LC connectors. This transceiver is compliant with IEEE 802.3 100GBASE-LR4, SFF-8665 and SFF-8636 standards. 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 100G telecom connections, data center, high-performance computing networks, enterprise core and distribution layers, campus networks etc.
Note: The FS P/N is changed from QSFP28-LR4-100G to QSFP-LR4-100G, but the product is the same. Only the FS P/N has been changed.
