Use a duplex fiber optic cable with LC connectors, paired with a compatible SFP or SFP+ transceiver module, to connect to the fiber optic port of a switch.

Required Components

1. SFP/SFP+ Transceiver Module: Most modern fiber-enabled switches require an SFP (1G) or SFP+ (10G) module. The module type must match the fiber optic cable type (single-mode or multimode) and the switch's bandwidth requirements .
2. Fiber Optic Cable: Use a duplex (two-strand) fiber optic cable. Single-mode fiber (OS2) is suitable for long-distance connections, while multimode fiber (OM3) is used for shorter distances, such as within a data center or server room .
3. Connectors: Terminate the fiber cable with LC-style connectors, which are standard for most SFP/SFP+ modules .

Connection Guidelines

• Insert the SFP/SFP+ module into the switch's fiber port. These modules are typically hot-swappable, so the switch does not need to be powered down .
• Connect the duplex fiber cable to the module, ensuring that the transmit (TX) of one end connects to the receive (RX) of the other end to avoid signal mismatch .
• Check compatibility: Ensure the SFP module, fiber type, and switch port all match. Mixing unsupported modules or cable types can cause unstable links or failure to recognize the module .
• Optional: For short distances, Direct Attach Cables (DACs) with pre-terminated SFP modules on each end can be used as a low-cost alternative .

Summary

To connect a fiber optic port on a switch, you need a duplex fiber optic cable with LC connectors and a compatible SFP or SFP+ transceiver module. Choose single-mode or multimode fiber based on distance requirements, and ensure proper TX/RX alignment between devices for reliable network communication .
