Do these require multimode or single-mode fiber, and what connector is used for the 80km run?

For the 80km ultra-long-haul transmission, you must use Single-Mode Fiber (SMF). The module uses a standard Duplex LC interface. It leverages LAN-WDM technology across four wavelengths to achieve the 80km reach over your standard SMF patch cords.

We need to deploy these in outdoor telecom cabinets. Does this module support extreme industrial temperatures?

This specific LQ-LW40L-ZR4C model is commercial-grade, supporting 0°C to 70°C, which is perfect for indoor climate-controlled server rooms. If you need optics for harsh outdoor environments (-40°C to 85°C), please contact us, and we can supply the industrial-rated equivalents.

We use a mix of Cisco Nexus and Juniper QFX switches. Will these 40G QSFP+ optics plug and play without triggering proprietary lockouts?

Absolutely! The LQ-LW40L-ZR4C is fully MSA compliant and rigorously tested for multi-vendor interoperability. You can seamlessly link Cisco, Juniper, Arista, and Dell gear without any "unsupported transceiver" errors or protocol mismatches.

We have strict enterprise audits. Does this 80km transceiver fully meet IEEE and MSA standards?

Yes, it is 100% compliant with the IEEE 802.3ba 40GBASE standards and QSFP+ MSA specifications. You can confidently deploy them in highly regulated corporate or telecom environments knowing they meet all global optical networking protocols.

Our procurement team needs around 50 of these modules for a metro network upgrade. Are there tiered discounts for larger B2B rollouts?

Yes, we offer significant volume discounts! For B2B orders over 50 units, our enterprise pricing drastically lowers the per-unit cost. Just reach out to our sales team directly, and we’ll prepare a customized, highly competitive quote for your project budget.

I needed the sfp cage quickly. Did not want to spend a whole lot of time trying to muddle through a complicated website looking for what I wanted. LINK-PP did just that. Up to this point I did not have a favorite site for my needs. Now I do.
