What is the maximum data rate of this module?

It supports a maximum data rate of 1.25 Gbps for gigabit networking.

Does this transceiver require a specific matching model?

Yes, it must pair with LS-BL49311G-10C to achieve bidirectional communication.

Can I use this module with multi-mode fiber?

No, it is engineered exclusively for single-mode fiber patch cables.

What type of laser transmitter does it utilize?

It utilizes a highly cost-effective 1310nm Fabry-Perot (FP) laser transmitter.

Hi, will this 1G BiDi SFP work with my mixed rack of Cisco and Ubiquiti switches?

Absolutely! The LS-BL31491G-10C features excellent OEM compatibility and has been thoroughly tested on Cisco, Ubiquiti, and other major multi-brand switch environments for seamless 1G Ethernet deployment.

Does this module support standard telecom industry protocols like SONET/SDH or just Gigabit Ethernet?

This specific module is optimized for 1G Ethernet and standard Fiber Channel protocols. It fully complies with IEEE 802.3ah and standard SFP MSAs, ensuring robust protocol adaptation for campus and enterprise networking.

Is there an industrial wide temperature version available? We are deploying in outdoor cabinets.

The standard LS-BL31491G-10C operates at commercial temps, but we do offer an industrial-grade wide temp version specifically designed for harsh outdoor base station backhaul environments.
