Q: This module lists a commercial working temperature of 0 to 70°C. Do you have an industrial version for harsh outdoor cabinet deployments? By S***s on 2026-07-16
A: 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. By admin on 2026-07-16
Q: Are these LS-SC49311G-10C transceivers compatible with Cisco and Ubiquiti switches in a mixed environment? By S***s on 2026-04-07
A: 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. By admin on 2026-04-07
Q: How does the performance of this 1.25G module compare to OEM brands? Is it a true cost-effective alternative? By D***n on 2026-04-06
A: 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. By admin on 2026-04-06
Q: 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? By B***n on 2025-10-28
A: 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! By admin on 2025-10-28
