Q: We need to deploy these in multiple data centers. Is there any discount if we buy 500+ units? By K***z on 2026-08-15
A: Absolutely. We offer tiered B2B wholesale pricing. The price drops significantly for large volume rollouts, and you can contact our sales team directly for a custom bulk quote on the LS-CW5310-40I. By admin on 2026-08-15
Q: What’s the typical lead time for these? We have a tight deadline for a campus fiber upgrade in Europe. By S***z on 2026-05-04
A: We usually hold solid inventory! If it's in stock, the lead time is 5-7 days globally via FedEx. For massive out-of-stock orders, it takes about 4-6 weeks to manufacture and deliver. By admin on 2026-05-04
Q: What kind of fiber patch cables do I need for this 40km transceiver? By E***k on 2026-04-21
A: You’ll need standard Single-Mode Fiber (SMF) cables equipped with Duplex LC connectors. This setup is ideal for minimizing signal dispersion and ensuring exceptional signal integrity over long-distance metro links and enterprise networks. By admin on 2026-04-21
Q: Are these modules going to throw error codes on Cisco Catalyst and Juniper EX series switches? By J***g on 2026-04-16
A: No worries there! They are fully OEM compatible and plug-and-play. We’ve tested them extensively on Cisco, Juniper, HPE, and Dell gear with zero unsupported transceiver errors. DOM/DDM monitoring works perfectly too. By admin on 2026-04-16
