Utilising a 4-lane CWDM design across the 1310nm wavelength window (1271nm, 1291nm, 1311nm, 1331nm), it delivers full 40GBASE-LR4 throughput over a single duplex LC fibre pair — making it ideal for building-to-building and campus backbone links where distance matters.\u003cbr\u003e\u003cbr\u003eCompliant with IEEE 802.3ba 40GBASE-LR4 and QSFP+ MSA (SFF-8436) standards, this hot-pluggable transceiver supports Digital Optical Monitoring (DOM) via I2C for real-time visibility into operating parameters including temperature, voltage, and optical power. With a maximum power draw of 3.5W and RoHS compliance, it integrates cleanly into high-performance Arista switching platforms.
