Cloud and AI applications have driven the need for data rates exceeding 100 Gb/s, leading to a shift towards high-speed, low-power 400 Gb/s connections. To support the short-reach application space inside data centers, the fiber optics industry has developed two IEEE 400G Ethernet standards: 400G SR4.2 and 400G SR8.

Do you know the difference between the two packages? How to correctly select the 800G optical module you need? This article will take you to understand the two encapsulation types of 800G optical modules: OSFP and QSFP-DD.

Recommendations for Using Single-mode and Multimode SFP Modules Single-mode and multimode SFP modules can be deployed in switch ports to facilitate communication via fiber optic or copper cables.

CWDM vs. DWDM. Choosing the right WDM technology depends on your specific network requirements, including the number of channels needed, transmission distance, power budget, and overall cost considerations.
