Looking to mass deploy these for our campus fiber network. Any chance you offer B2B bulk pricing for 200+ units?

Yes, we provide tiered bulk discounts for data centers, ISPs, and enterprise deployments. Just drop a message to our sales team with your exact quantity for a custom quote to optimize your procurement budget.

Are these 1.25G BiDi SFP transceivers compatible with Cisco and Ubiquiti switches out of the box?

Absolutely! They comply with the SFP MSA standard and feature excellent OEM compatibility, meaning true plug-and-play operation for Cisco, Ubiquiti, MikroTik, and most major switch brands without throwing unrecognized module errors.

Can I hook these up to multi-mode fiber, or do they strictly need Single Mode Fiber (SMF) with Simplex LC?

This specific transceiver is designed exclusively for Single Mode Fiber (SMF) using a Simplex LC/UPC connector to achieve the 20km range. Connecting it to multi-mode fiber will cause severe signal degradation.

The commercial temp (0~70°C) is cool for indoor racks, but we've got outdoor cabinets. Do you guys make an industrial wide-temp version?

We sure do! While this model is optimized for commercial use, we offer industrial-grade counterparts that operate flawlessly from -40°C to 85°C. They are perfect for extreme environments like base station backhaul or harsh outdoor enclosures.
