Do these Gigabit Ethernet SFPs meet CE and RoHS standards for deployment in European data centers?

Yes, they do. All our SMF optical transceivers are fully certified and strictly comply with CE, RoHS, FCC, REACH, and UKCA standards, ensuring complete industry compliance for global data center deployments.

Hello, will this 1.25G SFP SC module work with both Cisco and Juniper switches in the same rack?

Yes, absolutely! Our transceivers are MSA compliant and undergo rigorous multi-brand switch compatibility testing. They ensure seamless interoperability across Cisco, Juniper, Ubiquiti, Mikrotik, and other major OEM equipment.

How fast can you ship 500 of these BiDi SFP modules? We've had major supply chain and delay issues with other vendors.

We maintain a highly stable global supply chain. With our current active inventory, in-stock items like this module usually ship within 2 business day. Backorders are typically processed in just a few days to keep your project on schedule!

We need to install these in non-climate-controlled outdoor cabinets. Is there an industrial wide-temperature version available?

This specific LS-SC31491G-10C model has a 0 to 70°C operating temperature designed for indoor and temperature-controlled environments. However, we do offer the LS-SC31491G-10I model, which supports industrial wide temperatures from -40 to 85°C.

Replaced our old dual-fiber links with this Gigabit Ethernet SFP. The 1310nm/1490nm BiDi setup drastically cut our cabling costs. Performance is indistinguishable from $50 name-brand modules in our data center.
