What is the power consumption of 100g QSFP28?
Knowledge Base + 2024.01.12

The power consumption of a 100G QSFP28 (Quad Small Form-factor Pluggable) module can vary depending on the specific type and the features it supports. QSFP28 modules are used in high-speed data communication applications, and their power consumption is an important consideration, especially in data center environments. Here are general guidelines:

  • Typical Power Consumption: The typical power consumption of a 100G QSFP28 module is in the range of 3 to 4 watts.

  • Power Classifications: QSFP28 modules are often classified into different power classes based on their power consumption. Classes such as Class 3 and Class 4 are common, with Class 4 modules generally having higher power consumption.

  • Multirate Support: Some QSFP28 modules support multiple data rates, which can impact power consumption. For example, a module that supports 25G, 40G, and 100G may have variable power consumption based on the selected data rate.

It's important to check the datasheet and specifications provided by the manufacturer of the specific QSFP28 module you are using for accurate and detailed information on power consumption. Different manufacturers and models may have variations in power characteristics.
