Our outdoor street cabinets get extremely hot. Does this module come in an industrial wide-temperature version?

This specific LQ-LW112-ER4C operates at commercial temp (0°C to +70°C). However, we can custom-build industrial-grade (-40°C to +85°C) versions upon request for your harsh outdoor environments.

Hey guys, will this 100G QSFP28 module talk smoothly with my existing Cisco Nexus switches and FS network cards?

Yes, absolutely! These modules are strictly tested to guarantee 100% interoperability with Cisco, FS, and other major OEM equipment without triggering any vendor lock-in warnings.

We already have existing OS2 single mode fiber installed in the campus. Do we need any special adapters for this?

No special adapters needed. This transceiver uses a standard Duplex LC/UPC connector and is perfectly optimized for standard Single Mode Fiber (SMF) for transmission up to 40km.

Are these QSFP28 SMF modules compliant with international data center standards?

Yes, they are fully certified under ISO 9001, CE, RoHS, and FCC. We ensure rigorous MSA standard compliance for safe, long-term 100G Ethernet and telecom operation globally.

We are planning a massive data center upgrade. Do you offer volume discounts if we buy 100+ units of this 40km LC optical module?

For sure! We support tiered B2B pricing. Purchasing 100 units drops the unit price significantly, and we can also set up Net Terms to help better manage your enterprise expenditure.

Great value for dollar. Has been as reliable and high-performing as others I've paid 8-10x more for. At this price, you can purchase spares and still be considerably less than one of the name brand models.
