100G QSFP28 10km BIDI

Q: How many types of 100G QSFP28 optical modules are there?

A: Currently, there are several types of 100G optical modules in the market, including 100G QSFP28 SR4, 100G QSFP28 PSM4, 100G QSFP28 CWDM4, 100G QSFP28 LR4, 100G QSFP28 ER4, and 100G QSFP28 ZR4. For detailed parameters, refer to the table below.

Q: How does wavelength division multiplexing technology work in 100G QSFP28 optical modules?

A: For instance, LR4 and CWDM4 optical modules utilize wavelength division multiplexing technology to divide data into different wavelengths, transmit them simultaneously over the same fiber, and then demultiplex them at the receiving end, achieving high-density transmission.

Q: What is the bit error rate of 100G QSFP28 optical modules?

A: The bit 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: Pay attention to transmission distance, fiber type, power consumption, vendor compatibility, price, support for hot-swapping, future upgrade paths, etc.

Q: How are maintenance and troubleshooting performed on 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 integrity.

Q: What are the differences between 10G QSFP28 and QSFP56 optical modules?

A: QSFP56 optical modules support a rate of 200Gbps, which is twice that of QSFP28. They are mainly used in higher-speed network environments and have different interfaces and sizes.

Q: How is the signal integrity of 100G QSFP28 optical modules ensured?

A: Signal integrity is ensured through high-quality optical components, excellent circuit design, digital signal processing techniques (such as forward error correction), and appropriate shielding measures.
