To connect a jumper wire to a single-optical module, ensure the fiber type and module wavelength match, insert the optical module correctly, and attach the fiber jumper without bending or contaminating the connectors.

Step-by-Step Connection

1. Verify Fiber Type and Module Compatibility Use a single-mode fiber jumper for long-distance transmission. Ensure the optical module at both ends supports the same wavelength; typically, single-mode modules are yellow, while multimode modules are orange . Mismatched wavelengths can cause signal loss or failure. 2. Prepare the Optical Module Insert the optical module into the SFP or eSFP port of your device. For proper orientation, check the label: the labeled side usually faces upward for SFP1 and downward for SFP2 . Ensure the module is fully seated and secure. 3. Connect the Fiber Jumper

• Align the connector type of the jumper (LC, SC, ST, etc.) with the module port .
• Gently insert the fiber jumper until it clicks into place. Avoid excessive force.
• Do not bend the fiber sharply; maintain a minimum bend radius to prevent attenuation .
• Use protective caps on unused connectors to prevent dust or oil contamination. 4. Check the Connection
• Confirm the link is active by observing the device's status LEDs.
• If using dual-plane redundancy, connect SFP1 and SFP2 simultaneously to the monitoring system if required . 5. Disconnecting the Jumper
• Press the clip on the connector before pulling it out.
• Remove the optical module by the handle, waiting at least 0.2 seconds between removal and reinsertion to avoid damage .

Additional Tips

• Keep the fiber clean; dust or oil can degrade signal quality.
• Choose jumper length according to your setup (0.5m to 10m or more) and cable jacket type based on fire safety requirements .
• Avoid twisting or looping the fiber excessively to maintain low attenuation. By following these steps, you ensure a secure, low-loss connection for your single-optical module while protecting the fiber and module from damage.
