What is the maximum power consumption of QSFP28?
Knowledge Base + 2024.01.09

The power consumption of a QSFP28 (Quad Small Form-Factor Pluggable 28) transceiver module can vary depending on the specific type of optics and the features it supports. QSFP28 is a high-speed, compact transceiver used in data centers and telecommunications networks for 100 Gigabit Ethernet (100GbE) and other high-speed applications.

As of my last knowledge update in January 2022, the typical power consumption of a QSFP28 transceiver is in the range of 3.5 watts to 4.5 watts. However, it's important to note that different types of QSFP28 modules may have varying power requirements based on factors such as the specific optics (SR, LR, ER, etc.) and any additional features or functionalities the module may support.

For accurate and up-to-date information on the maximum power consumption of a specific QSFP28 module, it is recommended to refer to the datasheet or technical specifications provided by the transceiver's manufacturer. Manufacturers typically provide detailed information on power requirements, including the maximum power consumption under different operating conditions.
