An operation method of a network device and a control chip of the network device are provided. The network device receives an input signal through a fiber medium. The operation method includes the following steps: setting a target speed of the network device to a first speed; transmitting and/or receiving a data at the first speed; and setting the target speed of the network device to a second speed which is different from the first speed when the amplitude or energy of the input signal is not greater than a threshold.

Operation method of network device and control chip of network device

A communication apparatus with transmitted rate detecting function and the method therefore is provided. The communication apparatus receives an input signal transmitted at a first rate or a second rate from a remote apparatus. The method includes setting the communication apparatus to operate at an initial receiving rate; sampling the input signal by a specific sampling frequency to generate a sample result; estimating the input transmitted rate of the input signal according to the sample result so as to set the receiving rate of the communication apparatus at a working rate; and communicating with the remote apparatus at the working rate. The second rate is higher than the first rate, and the specific sampling frequency is associated with the initial receiving rate.
