QSFP28 (Quad Small Form-factor Pluggable 28) modules support various data rates depending on the specific implementation and the networking standard they are designed for. QSFP28 is commonly used for high-speed data transmission in data centers and telecommunications networks. Here are some common data rates associated with QSFP28:
100 Gigabit Ethernet (100G): QSFP28 modules are widely used for 100 Gigabit Ethernet connections, supporting a data rate of 100 gigabits per second (Gbps). This is a common application for QSFP28 in data center networks.
25 Gigabit Ethernet (25G): QSFP28 modules can also be used for 25 Gigabit Ethernet connections. In some cases, they might be configured for breakout applications, where a single QSFP28 port is split into four separate 25G connections.
Other Higher Data Rates: QSFP28 modules are designed to support even higher data rates beyond 100G. For example, they can be used for 40 Gigabit Ethernet or 50 Gigabit Ethernet connections, depending on the specific implementation and the networking standard.
It's important to note that the actual data rate supported by a QSFP28 module depends on factors such as the type of transceiver, modulation scheme, and the networking standard being used. Always refer to the specifications provided by the manufacturer of the QSFP28 module for accurate information on the supported data rates for a specific module.
