We currently use expensive original OEM optics for our 2.5G base station backhaul. Can this module truly match the original performance while saving our budget?

Without a doubt. Our transceiver uses high-quality DFB transmitters and PIN receivers to match or even exceed original OEM performance. You get the exact same 80km transmission stability and advanced DOM features, but at a fraction of the cost, maximizing your ROI.

What specific fiber patch cables do we need for this module? Does it use standard duplex or simplex?

Thanks to its advanced WDM (Wavelength Division Multiplexing) technology, it transmits and receives over a single strand of fiber. Therefore, you only need a Simplex LC Single Mode Fiber (SMF) patch cable. This design effectively cuts your optical cabling costs in half!

I'm a procurement manager planning a large-scale campus fiber networking project. Do you offer net terms or any bulk purchase discounts for orders over 100 units?

Yes, we highly support enterprise B2B customers. For batch deployments over 100 units, the unit price drops significantly, and we do offer flexible net terms to help manage your project budget. Feel free to contact our sales team for an exact quote!

We use a mix of Cisco, Juniper, and Arista switches in our data center. Is this 2.5G SFP BiDi module MSA compliant and fully interoperable across different OEM brands without throwing errors?

Yes, absolutely! This LS-BL55492G-80I module is 100% MSA compliant. We conduct strict compatibility testing in our lab to ensure seamless plug-and-play interoperability across all major switch brands like Cisco, Juniper, and Arista.
