Q: What are the data rates and modulation formats used by 800G OSFP/QSFP-DD modules?

A: As previously mentioned, all 800G optical modules use 8 electrical lanes for bidirectional transmission. Each electrical lane consists of one transmit channel and one receive channel, operating at a data rate of 100Gb/s per channel. Therefore, the total bandwidth of the module is 800Gb/s. Additionally, the optics output of Fast (FS) 800G modules consists of 8 optical wavelengths, with each channel on each wavelength utilizing 100G PAM4 modulation.

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

A: 800G optical modules employ PAM4 modulation, which enhances network performance and increases data rates. Compared to traditional NRZ modulation used in lower-speed optical modules, PAM4 allows each signal to carry 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 utilizing PAM4 modulation, 800G optical modules can transmit more data while using the same channel bandwidth, making them an ideal choice for applications such as data centers and cloud computing.

Q: What is the maximum power consumption of 800G OSFP and QSFP-DD optical modules?

A: The power consumption of 800G optical modules ranges from 13W to 18W per port.

Q: Do 800G optical modules support backward compatibility?

A: The backward compatibility of 800G optical modules depends on specific design and implementation. Some 800G optical modules are designed to be backward compatible with 400G or 200G optical modules, enabling smooth transitions and interoperability in existing networks. For example, the 800G OSFP SR8 optical module supports applications such as 800G Ethernet and can be split into two 400G SR4 channels. Compatibility should be confirmed with the optical module supplier before deployment.

Q: Which industry standards do 800G optical modules comply with?

A: 800G optical modules comply with IEEE 802.3ck and OSFP MSA standards. These standards are managed by industry alliances such as IEEE (Institute of Electrical and Electronics Engineers), OIF (Optical Internetworking Forum), and QSFP-DD MSA (Quad Small Form Factor Pluggable Double Density Multi-Source Agreement), covering specifications, electrical interfaces, and signaling protocols for 800G optical modules.

Q: What are the key highlights of 800G optical modules?

A: The packaging of 800G optical modules (such as QSFP-DD or OSFP) is compact and low-power, supports multiple modulation formats, interoperates with existing network infrastructures, enables high-speed data transmission, and is suitable for ultra-scale data centers and cloud infrastructures, offering higher bandwidth capabilities.

Q: Will QSFP-DD remain the mainstream packaging for 800G?

A: As mentioned earlier, QSFP-DD (QSFP56-DD) is more suitable for data center applications compared to OSFP. With the increasing pressure on intra-data center bandwidth due to the aggregation of east-west traffic, high-speed optical modules are seeing reduced time gaps in their application between telecom and data communication markets. 400G is expected to be widely adopted first in the data center market, meaning QSFP-DD is likely to benefit initially from this favorable development outlook. Currently, 400G is entering a golden period of development, with major manufacturers launching QSFP-DD optical modules, DACs, and AOCs to seize market opportunities.
