The power consumption (wattage) of a QSFP (Quad Small Form-Factor Pluggable) transceiver can vary depending on the specific type and standard of the QSFP module. QSFP modules are available for various data rates and applications, such as 40 Gigabit Ethernet (40GbE), 100 Gigabit Ethernet (100GbE), or InfiniBand connections.

The power consumption is influenced by factors such as the type of optics (e.g., SR4, LR4, PSM4), the number of channels or fibers used, and the technology employed in the module. As a result, there isn't a single wattage value that applies to all QSFP modules.

For accurate and up-to-date information on the power consumption of a specific QSFP module, it's recommended to refer to the datasheet or technical documentation provided by the manufacturer of the QSFP module in question. The datasheet typically includes details on power requirements, including both the typical and maximum power consumption values.
