Our IT procurement policies require strict adherence to international safety and environmental regulations. Does this transceiver meet global industry standards?

Yes, this 1G optical module is fully compliant with RoHS, CE, FCC, and REACH standards. It also meets FDA Class 1 laser safety requirements and SFF-8472 digital diagnostic monitoring guidelines, ensuring completely safe, compliant, and eco-friendly global deployments.

We're planning a massive campus fiber network upgrade and need to deploy about 500 units of these 100km DOM Simplex LC modules. Are there any bulk purchasing discounts available?

Definitely. We offer tiered pricing for large B2B deployments to help you optimize your procurement budget. For an order of 500 units, please contact our sales team directly, and we’ll provide a customized quote with significant volume discounts.

The standard operating temperature is 0-70°C for indoor scenes, but we need to deploy some in harsh outdoor cabinets where temperatures drop below freezing. Do you offer an industrial version?

Yes, we do! While the LS-BL55491G-A0C is designed for commercial temperatures (0 to 70°C), we also manufacture the LS-BL55491G-A0I, which is the industrial-grade equivalent. It supports a much wider temperature range of -40°C to 85°C, making it perfect for extreme outdoor and industrial environments.

Hey there, we run a mix of Cisco, Juniper, and Arista switches in our data center. Is this LS-BL55491G-A0C fully OEM compatible across different brands without throwing unsupported errors?

Yes, absolutely! This 1G BiDi SFP is strictly MSA compliant. It undergoes extensive multi-brand switch compatibility tests to ensure true plug-and-play interoperability with major networking vendors, meaning you can deploy it without worrying about proprietary lock-ins or compatibility warnings.
