Choose single-mode fiber for longer-distance links, with the listed single-mode SFP transceiver supporting transmission up to 20 kilometers, or choose multimode fiber for shorter, in-building connections. Match the SFP optic to the fiber type and standard, such as 10GBase-SR with OM3 or OM4 multimode fiber, or 10GBase-LRM with OM1 or OM2 multimode fiber.

Check that the equipment has a matching SFP or SFP+ port, supports the transceiver’s data rate and Ethernet standard, and accepts its fiber type, connector style, wavelength, and transmission distance. Also verify the transceiver’s compatibility list, including vendor or device restrictions, and match the fiber mode and cable specifications, such as single-mode or multimode fiber.

Compare the connector type, such as a duplex LC interface or a direct-attach SFP+ connection, along with the fiber standard, such as 1000Base-LX, 10GBase-SR, or 10GBase-LRM, and confirm that it matches your equipment and fiber. Check the required data rate, such as 1.25 Gbps or 10 Gbps, and the supported transmission distance, which can range from up to 300 meters over OM3 multimode fiber to up to 20 kilometers over single-mode fiber, depending on the transceiver.

Use a direct attach cable for a short 10 Gigabit link between compatible SFP+ ports, especially for server, storage, or switch connections where a preterminated cable and low-latency connection are useful. Choose SFP fiber optic connectors and transceivers when the link requires a separate optical fiber run, a specific single-mode or multimode fiber type, or more reach than a short direct attach cable provides.
