Optical modules are designed with a maximum supported transmission rate, such as 1G, 10G, 25G, 100G, 400G, or 800G, which defines the speed at which data can be transmitted over the fiber link . This rate is a key parameter for network bandwidth and is typically fixed by the module's hardware and form factor (e.g., SFP, QSFP28, QSFP-DD). The module's speed must match the switch, router, or transponder port to ensure proper operation .
Certain advanced optical modules, such as 400G Digital Coherent QSFP-DD modules, allow configuration of parameters that indirectly affect speed and performance. These include:
