Using four CWDM LAN WDM channels (1271, 1291, 1311, 1331 nm) over a single duplex LC fibre pair, it complies with IEEE 802.3ba and the QSFP+ MSA (SFF-8436\/SFF-8636), ensuring broad compatibility with standard 40GBASE-ER4 interfaces.\u003cbr\u003e\u003cbr\u003eDigital Optical Monitoring (DOM) provides real-time visibility into optical power levels, temperature, bias current, and supply voltage for simplified fault isolation and proactive maintenance. The hot-swappable QSFP+ form factor allows non-disruptive replacement, while a maximum power draw of just 3.5W keeps thermal overhead low.
