The Arista Networks LNF-QSFP-100/112G-LR4-20 Compatible QSFP28 Dual Rate Optical Transceiver Module is designed for use in 100GBASE Ethernet and 4x28G OTN client interfaces throughput up to 20km over single mode fiber(SMF) using a wavelength of 1310nm via duplex LC connectors. Taking BOX+FPC+PCBA separate design, it has great reliability, airtightness and heat dissipation performance. This transceiver is compliant with IEEE 802.3ba 100GBASE-LR4 and OTU4 4I1-9D1F 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 100G Ethernet, 112G OTN OTU4, telecom, service provider applications and 5G wireless network.
