This module lists a commercial working temperature of 0 to 70°C. Do you have an industrial version for harsh outdoor cabinet deployments?

Yes, we do. If your outdoor networking cabinets or cell tower edge deployments experience extreme weather, we highly recommend our industrial-grade equivalent (e.g., LS-SC49311G-10I), which reliably operates in wide-temperature environments from -40°C to +85°C.

Are these LS-SC49311G-10C transceivers compatible with Cisco and Ubiquiti switches in a mixed environment?

Yes, absolutely. These 1G BiDi SFPs are strictly MSA compliant. Our networking engineers rigorously test them across multi-brand setups, ensuring seamless plug-and-play interoperability with Cisco, Ubiquiti, Juniper, and other major OEM networking equipment.

How does the performance of this 1.25G module compare to OEM brands? Is it a true cost-effective alternative?

It delivers identical core performance to original OEM transceivers but at a fraction of the cost. Equipped with top-tier DFB lasers and real-time DOM/DDM monitoring, you get 100% reliable 10km transmission, making it highly cost-effective for data center interconnects and enterprise upgrades.

What type of fiber adapter and cable do I need for this BiDi module to link my home 10G NAS gateway to my main remote switch?

You will need a standard Single-Mode Fiber (SMF) patch cable with a Simplex SC connector. Because it utilizes advanced WDM technology (1490nm-TX/1310nm-RX), a single fiber strand is all you need for bidirectional communication. Just make sure to pair it with a complementary 1310nm-TX/1490nm-RX module on the other end of the link!
