Q: Can OSFP optical modules be inserted into QSFP-DD ports? Can QSFP-DD be inserted into OSFP ports?

A: No, OSFP and QSFP-DD are two physically different form factors. OSFP systems require OSFP optical modules and cables, while QSFP-DD systems require QSFP-DD optical modules and cables.

Q: How many electrical channels does an 800G optical module use?

A: An 800G optical module uses 8 electrical channels for data transmission, each channel comprising one receive channel and one transmit channel.

Q: What are the rate and modulation format used in 800G OSFP/QSFP-DD modules?

A: As mentioned earlier, all 800G optical modules use 8 electrical channels for bi-directional transmission. Each channel operates at a data rate of 100Gb/s, resulting in a total bandwidth of 800Gb/s for the module. Additionally, FS 800G optical modules utilize 8 optical wavelengths, with each channel employing 100G PAM4 modulation.

Q: What is the significance of using PAM4 modulation technology for digital signal transmission in 800G optical modules?

A: Adopting PAM4 modulation in 800G optical modules enhances network performance and increases data rates. Compared to traditional NRZ modulation used in lower-speed optical modules, PAM4 allows each signal to transmit twice the amount of data. This capability enables 800G optical modules to achieve data rates of up to 800Gbps on a single optical channel. By leveraging PAM4 modulation, 800G optical modules can transmit more data while utilizing the same channel bandwidth, making them ideal for applications such as data centers and cloud computing.
