How many channels does a QSFP+ module have compared to SFP+?

Two channels
Three channels
Four channels
Five channels

The correct answer is: Four channels

A QSFP+ (Quad Small Form-factor Pluggable Plus) module is designed to support four channels of data transmission, allowing for much higher data rates compared to SFP+ (Small Form-factor Pluggable Plus) modules, which typically support just a single channel. The four channels of the QSFP+ can work together to achieve high bandwidth, commonly used for applications requiring 40 Gbps speeds, such as data centers and high-performance computing. In contrast, SFP+ modules are typically limited to 10 Gbps per port, hence they have only one channel. This fundamental difference in the number of channels illustrates the QSFP+ module's ability to aggregate data transmission more effectively, which is quite advantageous in environments where bandwidth is critical. Other options indicating two, three, or five channels do not align with the standard specifications of the QSFP+ module, making four channels the correct and accurate answer.
