Single-mode LC fiber transceivers use single-mode fiber for longer links, with the assortment supporting distances up to twenty kilometers and data rates up to 10 Gbps. Multimode LC fiber transceivers use multimode fiber, commonly at 850 nanometers, for shorter links such as up to 300 or 550 meters, with options supporting 1 Gbps or 10 Gbps.

SFP LC fiber transceivers commonly support about 1 Gbps, while SFP+ LC transceivers support up to 10 Gbps, with some models designed for multimode or single-mode fiber links. Each transceiver should match the host device’s SFP or SFP+ port, supported data rate, fiber type, wavelength, and link distance.

Check that the transceiver matches the equipment’s SFP or SFP+ port, data rate, fiber type, wavelength, LC connector configuration, and supported link distance. Also confirm standards and platform compatibility, and use matched wavelength pairs for bidirectional single-mode links when required.

Simplex LC fiber transceivers use one fiber strand, duplex transceivers use separate strands for transmit and receive, and bidirectional transceivers send and receive over one strand using different wavelengths. This affects cable count, patch-panel planning, and link budget, so match the transceiver to the fiber type, LC connector configuration, port speed, and, for bidirectional links, the required wavelength pair at each end.
