Just to be 100% sure before I finalize the PO, this requires standard single-mode fiber with a Duplex LC connector, right?

Spot on. This transceiver relies on Single-Mode Fiber (SMF) using standard Duplex LC physical interfaces. It utilizes 4-lane LAN-WDM MUX/DEMUX technology to push 40Gbps across that single pair of fiber.

We’re deploying a 70km metro link. Does this transceiver require inline optical amplifiers, or can we save on that cost?

You can definitely skip the extra hardware! Thanks to the high-sensitivity APD receiver and robust EML transmitter, it effortlessly supports up to 80km over single-mode fiber without any inline amplification, massively reducing your total cost of ownership.

Does this 40GBASE-ZR4 module play nice with a mixed network of Cisco Nexus core switches and Arista edge devices?

Absolutely! The LQ-LW40-ZR4C is highly compatible. We rigorously test it to ensure seamless interoperability across major brands like Cisco, Arista, Juniper, and Dell, eliminating vendor lock-in for your data center.

Our corporate procurement requires strict adherence to networking standards. Does this module support full DOM via I2C?

Yes! It is fully compliant with QSFP+ MSA and IEEE 802.3ba standards. It features a built-in I2C interface for real-time Digital Optical Monitoring (DOM/DDM), allowing your IT admins to track voltage, temperature, and channel power accurately.
