Hey, we're running a mix of Cisco Nexus and Arista switches in our core network. Will this 400G FR4 transceiver work seamlessly across both brands without raising third-party optic alarms?

Absolutely! The LQD-CW400-FR4C is fully OEM-compatible and coded to support Cisco, Arista, and other major networking brands like Juniper and Mellanox. You can deploy it confidently in mixed-switch environments without triggering compatibility errors.

Just to confirm before purchasing for our campus fiber ring—does this transceiver use a standard duplex LC connector, and is it compatible with our existing OS2 single-mode fiber (SMF)?

Yes! This 400G QSFP-DD optical module features an industry-standard Duplex LC interface. It is fully compatible with standard OS2 single-mode fiber (SMF) and supports transmission distances up to 2km utilizing 1310nm CWDM4 wavelengths.

I'm an IT procurement manager looking to order 200 units for a new datacenter build in Frankfurt. Do you offer B2B bulk discounts for large volume purchases?

Yes, we provide competitive tiered pricing for enterprise B2B customers. For an order of 200 pieces of our 400G QSFP-DD modules, you'll receive a significant bulk discount over the standard unit price. Please contact our live sales team for a custom quote!

Yes you can get this item for much cheaper elsewhere but who knows what kind of quality you\'re gonna be getting. And replacing that part and dealing network problems from low quality parts will cost you much more in the long run.
