Q: What does hot-swappable feature mean for 100G QSFP28 optical modules?
A: The hot-swappable feature means that the optical modules can be installed or removed without powering off the system, making maintenance and upgrades more convenient.
Q: How does wavelength division multiplexing (WDM) technology work in 100G QSFP28 optical modules?
A: For example, LR4 and CWDM4 optical modules use WDM technology to divide data into different wavelengths, transmit them simultaneously over the same optical fiber, and then demultiplex them at the receiving end, achieving high-density transmission.
Q: What is the error rate of 100G QSFP28 optical modules?
A: The error rate of 100G QSFP28 optical modules is very low, typically between 10^-12 to 10^-15, ensuring the accuracy of data transmission.
Q: What are the considerations for purchasing 10G QSFP28 optical modules?
A: Considerations include transmission distance, fiber type, power consumption, supplier compatibility, pricing, hot-swappable support, and future upgrade paths.
Q: How are maintenance and troubleshooting performed for 100G QSFP28 optical modules?
A: Regularly check optical power levels, use optical power meters and bit error rate testers, monitor temperatures, and clean fiber interfaces to ensure software and firmware updates for system maintenance.
