Connect the fiber optic ports of 3 S5130 switches

Use compatible SFP/SFP+ transceivers in paired ports and connect the switches with fiber cables according to the transceiver type and distance requirements.Step 1: Identify Fiber Ports and TransceiversThe H3C S5130 switches feature 10GE SFP+ fiber ports for high-speed connections . These ports support various GE and 10GE SFP/SFP+ transceivers, including single-mode and bidirectional (BIDI) modules. For BIDI transceivers, each end must use complementary wavelengths (e.g., SFP-GE-LX-SM1310-BIDI on one end and SFP-GE-LX-SM1490-BIDI on the other) to ensure proper communication .Step 2: Select Compatible Fiber CablesSingle-mode fiber (SMF) is recommended for long-distance connections (up to 80 km depending on the transceiver).Multimode fiber (MMF) is suitable for shorter distances (typically up to 300–400 meters).Use LC-LC connectors for SFP/SFP+ modules.Avoid installing BIDI transceivers in adjacent ports if using long-distance modules to prevent interference .Step 3: Connect the SwitchesInsert the appropriate SFP/SFP+ transceivers into the fiber ports of each switch.Connect the fiber cables between the switches, ensuring the transmit (TX) and receive (RX) directions match. For BIDI modules, the complementary wavelength pairing automatically handles TX/RX alignment.For three switches, you can create a triangle topology for redundancy:Switch A → Switch BSwitch B → Switch CSwitch C → Switch A This ensures that if one link fails, traffic can reroute through the remaining links.Step 4: Verify Link StatusCheck the system status LEDs on each switch to confirm the fiber ports are active .Use the switch CLI to verify the link:CodeCopydisplay interface brief Ensure the SFP/SFP+ ports show up status and correct speed (10G).Step 5: Best PracticesUse H3C-certified transceivers and cables to ensure compatibility and reliability .Maintain proper cable management and avoid bending fibers sharply.Keep fiber ports and connectors clean to prevent signal loss.Ground outdoor fiber runs properly if connecting through an optical distribution frame (ODF) or splice enclosure . By following these steps, you can successfully connect the fiber optic ports of three H3C S5130 switches, ensuring high-speed, reliable inter-switch communication.
