We're doing a massive data center interconnect upgrade and need to grab around 150 units. Do you guys offer any B2B bulk pricing?

Definitely! We fully support enterprise volume procurement. The cart automatically applies discounts for large orders, but for deployments of 100+ units, please hit up our B2B sales team directly for deeper net terms and customized quotes.

Hello, will this 400G QSFP-DD optic work with our Cisco Nexus 9000 core switches? I really don't want to deal with "unsupported transceiver" errors.

Yes, absolutely. The LQD-CW400-LR4C is fully QSFP-DD MSA compliant with custom EEPROM coding available. It functions plug-and-play in Cisco Nexus environments natively without triggering any third-party block alerts.

Are these optics strictly for Ethernet, or do they support industry protocols like InfiniBand? We need them for an AI HPC cluster setup.

They seamlessly handle both! They are fully compliant with IEEE 802.3bs for Ethernet and strictly adaptable to 400G InfiniBand NDR protocol standards. They deliver the massive bandwidth and ultra-low latency required for heavy AI nodes and server backend networks.

Just double-checking the fiber type—do I need an MPO trunk for this, or will my standard duplex LC single-mode patches work for a 10km link?

Your standard Duplex LC OS2 single-mode fiber (SMF) patch cables will work perfectly! This transceiver uses built-in CWDM technology to multiplex four wavelengths, running 400G over just two strands of fiber up to 10km. No MPO conversion required!

Procured 50 units for a commercial data center build-out. Complete QSFP-DD MSA compliance meant no vendor lock-in headaches. Optical DOM monitoring gives my IT admin team exact TX/RX power levels. Unbeatable ROI!
