1. Produktet er slutview
The Cisco SFP-10G-LR= is a high-performance SFP+ (Small Form-Factor Pluggable Plus) transceiver module designed for 10 Gigabit Ethernet long-reach applications. It provides a full-duplex 10 Gbps link over single-mode fiber (SMF) with an LC connector interface. This module is hot-swappable and can be inserted into an SFP+ port of a Cisco switch or router without powering down the device, facilitating network upgrades and maintenance.
It is specifically engineered for reliable data transmission over distances up to 10 kilometers (6.2 miles) on standard single-mode fiber, making it suitable for enterprise and data center networking environments requiring high-speed, long-distance connectivity.

2. Opsætning og installation
2.1. Sikkerhedsforanstaltninger
- Always wear an ESD (Electrostatic Discharge) wrist strap when handling the module to prevent damage from static electricity.
- Do not look directly into the optical ports when the module is powered on, as laser radiation can cause eye damage.
- Ensure the host device (switch/router) is compatible with SFP+ modules and specifically with the SFP-10G-LR model.
2.2. Installationstrin
- Prepare the Port: Ensure the SFP+ port on your network device is clean and free of debris.
- Orient the Module: Hold the SFP-10G-LR module with the label facing up (or according to your device's orientation guide).
- Indsæt modulet: Gently slide the module into the SFP+ slot until it clicks into place. Do not force the module. The module should sit flush with the device's front panel.
- Bekræft installationen: Check the module's status LED (if available on your device) or use the device's command-line interface (CLI) to confirm that the module is recognized and operational.
2.3. Tilslutning af fiberoptiske kabler
- Use only single-mode fiber optic cables with LC connectors.
- Remove the dust caps from both the module's LC ports and the fiber optic cable's LC connectors.
- Connect one end of the fiber optic cable to the SFP-10G-LR module's LC port. Ensure the transmit (TX) port on one end connects to the receive (RX) port on the other end, and vice-versa.
- Connect the other end of the fiber optic cable to the corresponding SFP+ module or device.
- Once connected, verify link status via device LEDs or CLI.
3. Betjening
Once installed and connected, the Cisco SFP-10G-LR= module operates automatically, providing a 10 Gigabit Ethernet optical link. It converts electrical signals from the host device into optical signals for transmission over single-mode fiber and vice-versa.
3.1. Link Status Indicators
Refer to your host device's (switch or router) documentation for specific LED indicators related to SFP+ port status. Typically, a solid green LED indicates a stable link, while a blinking LED may indicate activity or a problem. No LED or an amber/red LED usually signifies a link issue.
4. Vedligeholdelse
Proper maintenance ensures the longevity and optimal performance of your SFP-10G-LR= module.
4.1. Cleaning Optical Connectors
- Always use approved fiber optic cleaning tools and procedures.
- Never use alcohol or other solvents not specifically designed for fiber optic cleaning.
- Keep dust caps on the module's optical ports and fiber cable connectors when not in use.
- Contamination on the fiber end-faces is a leading cause of signal loss and can permanently damage the module.
4.2. Håndtering og opbevaring
- Store the module in its original anti-static packaging when not in use.
- Undgå at tabe modulet eller udsætte det for fysiske stød.
- Keep the module in a cool, dry environment, away from direct sunlight and extreme temperatures.
5. Fejlfinding
If you encounter issues with your SFP-10G-LR= module, consider the following troubleshooting steps:
- Ingen linklampe:
- Verify the module is fully seated in the SFP+ slot.
- Check that the fiber optic cable is correctly connected (TX to RX, RX to TX) at both ends.
- Inspect fiber optic cable for damage (kinks, breaks).
- Clean the fiber optic connectors and module ports.
- Sørg for, at den eksterne enhed er tændt, og at den tilsvarende port er aktiv.
- Intermittent Link/Packet Loss:
- Check for dirty or damaged fiber optic connectors.
- Verify the fiber optic cable length does not exceed the module's maximum supported distance (10 km for LR).
- Ensure the fiber type is single-mode (SMF).
- Check for excessive bends in the fiber cable.
- Modulet genkendes ikke:
- Remove and reinsert the module.
- Ensure the host device's software/firmware is up to date and supports the SFP-10G-LR module.
- Try the module in a different SFP+ port or a different compatible device if available.
If issues persist after performing these steps, contact Cisco Technical Support for further assistance.
