800G optical modules can be divided into multiple types according to packaging form, transmission distance and fiber type. The following are several common 800G optical module types and their characteristics:
OSFP packaging: OSFP packaging supports higher power consumption and heat dissipation capabilities, suitable for high-performance application scenarios.
QSFP-DD packaging: QSFP-DD packaging has more advantages in compatibility and cost control, and is suitable for scenarios with high space requirements.
800G OSFP-DR8/PSM8: Suitable for short-distance transmission within the data center, usually using single-mode optical fiber, supporting a maximum transmission distance of 500 meters.
800G OSFP-2FR4/2LR4: Through wavelength division multiplexing technology, single-mode optical fiber is used to achieve longer distance transmission, supporting a transmission distance of 2 kilometers.
800G QSFP-DD-DR8/PSM8: Similar to OSFP, but with a more compact packaging, suitable for scenarios with high space requirements.
