Q: How to select and pair fibers for 100G QSFP28 optical modules?
A: Selection depends on the module type:
- SR4/CWDM4: Utilize OM3 or OM4 multimode fibers according to the required distance.
- LR4/ER4: Employ single-mode fibers with LC-LC connectors; consider dispersion compensation.
- PSMF: Use single-mode fibers, taking into account fiber attenuation and distance requirements.
- eSR: Special scenarios may necessitate parallel fiber array cables.
Q: How to troubleshoot issues with 100G QSFP28 optical modules?
A: Troubleshooting steps:
- Verify physical connections are secure and fibers are clean.
- Measure receive and transmit optical power with a power meter to ensure they meet specifications.
- Inspect module status lights for error codes.
- Utilize digital diagnostic tools to analyze module parameters like temperature and voltage.
- Confirm switch firmware compatibility, attempt a reset, or replace the module if necessary.
Q: How does wavelength division multiplexing (WDM) technology work in 100G QSFP28 optical modules?
A: Modules like LR4 and CWDM4 employ WDM technology, dividing data into different wavelengths which are then simultaneously transmitted through a single fiber. Demultiplexing occurs at the receiving end, enabling high-density transmission.
Q: What is the bit error rate (BER) for 100G QSFP28 optical modules?
A: The BER for 100G QSFP28 optical modules is exceptionally low, typically ranging between 10^-12 and 10^-15, ensuring the accuracy of data transmission.
Q: What factors should be considered when purchasing 100G QSFP28 optical modules?
A: Considerations include transmission distance, fiber type, power consumption, vendor compatibility, price, support for hot swapping, and potential upgrade paths for the future.
