What is the bandwidth for rj11?

RJ11 connectors, commonly used for telephone lines, typically support a bandwidth of up to 1 MHz. This is sufficient for standard voice communication and low-speed data transmission, like dial-up internet. However, for higher bandwidth applications, such as DSL, the actual capacity can be higher, depending on the specific technology used and the quality of the line. Overall, RJ11 is not designed for high-speed data transfers compared to other connectors like RJ45.
