FAQs

SFP modules convert electrical signals to optical signals (or vice versa), enabling data transmission between networking devices such as switches and routers across various distances and media types.

Our SFP modules are MSA-compliant, ensuring broad compatibility with major equipment manufacturers. Verify compatibility through your device documentation, our online compatibility matrix, or by contacting our technical support team.

Yes, all our modules support hot-swapping. Use an ESD wrist strap during installation, handle modules by their edges, and ensure proper alignment before insertion to prevent damage.

Power consumption typically ranges from 1-2 watts. Operating temperature range is 0°C to 70°C (commercial) or -40°C to 85°C (industrial), with 5-95% non-condensing humidity tolerance.

Our modules come with a 3-year standard warranty covering manufacturing defects and performance issues under normal use. Extended warranty options are available for select products.

Technical documentation is available in our online knowledge base. Support can be accessed via email (support@bwnfibersfp.com), phone, or through our customer support portal.
