What does a QSFP+ connector support in terms of data transmission?

A QSFP+ (Quad Small Form-factor Pluggable Plus) connector supports a high-speed data transmission capability of 4x 28 Gb/s. This configuration allows for a total bandwidth of 112 Gb/s, making the QSFP+ a popular choice for applications that require significant data transfer rates, such as data centers and high-performance computing environments.

The QSFP+ connector is designed to handle multiple data channels simultaneously, hence the "4x" designation. Each of the four channels can transmit data at a rate of 28 Gb/s, which is essential for modern networking demands that involve transferring large volumes of data quickly and efficiently. This capability enables robust and agile connectivity that is crucial in today’s data-intensive applications.

Choosing 28 Gb/s per channel reflects the advancements in optical and electrical transmission technologies, which support higher speeds while maintaining reliability and low latency, a requirement for sophisticated networking setups. Thus, the choice that reflects the capabilities of the QSFP+ connector directly aligns with current networking standards.
