Cisco Meraki MS-series and select Cisco Catalyst platforms are natively supported by the Cisco MA-QSFP-40G-LR4, a QSFP+ transceiver engineered for high-speed enterprise networking. This module delivers 40 Gbps throughput over OS2 Single-Mode Fiber compliant with the IEEE 802.3ba 40GBASE-LR4 standard. The MA-QSFP-40G-LR4 employs four wavelengths—1271 nm, 1291 nm, 1311 nm, and 1331 nm—using LAN-WDM technology to multiplex 4 x 10G lanes onto a single fiber pair, reaching distances up to 10 km. Duplex LC connectors ensure seamless integration into modern data center cabling infrastructure, while support for Digital Optical Monitoring allows real-time module diagnostics. The transceiver operates across a commercial temperature range of 0°C to 70°C and passes native Cisco IOS and Meraki firmware validation out of the box, eliminating compatibility delays.

Network engineers and IT procurement teams standardizing on Cisco switching infrastructure select the MA-QSFP-40G-LR4 to scale campus backhaul and inter-datacenter links without proprietary optics lock-in. Its hot-swappable design enables field replacement during live operations, while RoHS compliance and QSFP+ MSA certification guarantee long-term supply continuity and ecosystem interoperability. Organizations requiring reliable 40 Gbps connectivity over extended single-mode runs benefit from the module's 64B/66B encoding efficiency and proven Cisco manufacturing pedigree.
