Will this 100G QSFP28 80km module work with our mix of Cisco Nexus and Arista datacenter switches?

Yes, these long-haul transceivers are strictly tested for OEM compatibility. They will plug and play seamlessly with Cisco, Arista, Juniper, Ubiquiti, and other major switch brands right out of the box without any vendor lock-in issues.

Can I use multimode fiber for a quick test in the lab, or is this strictly for single-mode?

This 1310nm LAN-WDM transceiver is designed exclusively for Single Mode Fiber (SMF) with a Duplex LC connector. To prevent receiver saturation and hardware damage on short test runs, we strongly recommend using OS2 SMF cable along with appropriate optical attenuators (usually 10dB to 15dB for lab testing).

We are rolling out a regional ISP upgrade and need about 40 of these 100G LAN-WDM modules. Do you offer bulk discounts?

Absolutely! For large-scale B2B procurements of our 100G QSFP28 80km transceivers, please contact our B2B sales team. We provide tiered volume pricing and dedicated procurement support for enterprise and ISP clients.

We plan to install these in unventilated outdoor telecom cabinets. Do you have an industrial wide-temperature version of this 100G optic?

This specific module is designed for standard commercial operating temperatures (0°C to 70°C). However, we do offer an industrial-grade version (-40°C to 85°C) for this exact 1310nm 80km spec. Please check our store or contact support directly for the industrial SKU.
