Will this 100G BiDi QSFP28 sync up seamlessly with our existing Cisco and Arista core switches without throwing third-party optic errors?

Absolutely! The LQ-BLA100-ZR4C is fully OEM compatible and has been rigorously tested across major switch brands to ensure pure plug-and-play interoperability without any vendor lock-in warnings.

We're planning a massive data center upgrade and need about 50 of these modules. Do you guys offer bulk pricing for enterprise procurement?

Yes, we provide tiered discounts for bulk orders. You can see the initial price drops directly on the product page for larger quantities, and our sales team can hook you up with specific net terms for large-scale IT deployments.

I see this unit supports 0°C to 70°C for indoor use. Do you manufacture an industrial wide-temperature version for our outdoor cell tower cabinets?

Currently, this specific model is optimized for commercial indoor and temperature-controlled datacenter environments (0°C to 70°C). However, we can custom-build industrial-grade transceivers (-40°C to 85°C) upon request. Please contact our technical support team for an exact quote.

Does this transceiver comply with standard IEEE specs for long-haul networks? Just want to be sure it aligns with our industry compliance.

Definitely. It strictly complies with QSFP28 MSA, SFF-8636, and the IEEE 802.3ba 100Gbase-ZR4 industry standards, making it fully compliant for standard long-haul network architectures.
