The specs say 0°C to 70°C. Do you make an industrial wide-temperature version for our outdoor telecom cabinets?

This specific LQ-CW40-FR4C is our commercial-grade module designed for indoor data centers. For harsh outdoor environments like base station backhauls, we highly recommend our industrial-grade variants which support extreme temperatures from -40°C to 85°C. Please contact our support team to spec out the right wide-temp 2km option for your setup.

We are looking to bulk deploy these across our new UK datacenter. Do you guys offer any B2B pricing discounts for orders over 100 units?

Yes, we provide tiered wholesale discounts. For orders exceeding 100 units, the price drops significantly, and any order over $600 includes free global shipping. Feel free to contact our sales team directly for a custom quote!

Can you confirm if this optic strictly complies with IEEE 802.3ba 40GBASE-FR4 standards? We need it for a government compliance project.

Yes, it is 100% compliant with IEEE 802.3ba 40GBASE-FR4, RoHS, and MSA standards. Built with premium DFB lasers and PIN receivers, it easily meets the rigorous regulatory and performance requirements for both government and enterprise telecom networks.

What kind of fiber patch cords do I need for this? Should I use MPO or standard LC?

This 40Gbps module features a standard Duplex LC interface. You will need standard Single Mode Fiber (SMF) patch cables, not MPO. It is designed for simple, plug-and-play integration into existing duplex LC fiber panels up to a 2km transmission distance.

Hello, will this 40G QSFP+ transceiver play nice if we mix Cisco Nexus and Arista switches in the same rack?

Absolutely! The LQ-CW40-FR4C is fully MSA compliant and undergoes strict multi-brand switch testing. It interoperates seamlessly with Cisco, Arista, Juniper, and other major OEM equipment without triggering vendor lock-in errors.

Tested this 40GBASE-FR4 optic on a Juniper switch for base station backhaul. MUX/DEMUX handles the 1271-1331nm wavelengths brilliantly. Under 3.5W power draw keeps the rack cool.
