I’m looking to outfit an entire server room and need about 200 of these 40G QSFP+ modules. Do you offer tier pricing or wholesale discounts for bulk corporate procurement?

Yes, we provide aggressive volume discounts for B2B clients! For a bulk purchase of 200 units, you will receive a significant price reduction compared to the single-unit cost shown. Reach out to our sales engineering team directly for a customized quote.

We use a mix of Cisco Nexus and Arista switches in our data center. Will this 40GBASE-LR4 module interoperate seamlessly without throwing third-party warning logs?

Absolutely. This QSFP+ module is thoroughly tested for OEM compatibility across major brands like Cisco, Arista, and Juniper. It's entirely plug-and-play and will integrate smoothly without triggering unsupported transceiver warnings.

We are on a tight schedule for a campus fiber network rollout next month. Are these 1310nm 10km modules in stock, and what’s your typical delivery cycle to Europe or the US?

We maintain a large, stable supply chain and keep extensive inventory of these standard 40G LR4 optics. Orders are typically processed within 24 hours, and expedited global shipping usually takes just 2 to 5 business days, ensuring you meet critical project deadlines.

Is this transceiver fully compliant with IEEE 802.3ba and standard MSA specifications? I need to ensure it meets strict industry compliance for our federal contracts.

Yes, the LQ-CW40-LR4C strictly complies with the IEEE 802.3ba 40GBASE-LR4 standard and all QSFP+ MSA specifications. It is also fully RoHS compliant, fulfilling the rigorous regulatory and operational demands of global enterprise and government deployments.
