Abstract
A noise detection device includes a connector used for connecting a multicore cable, a connector used for connecting the communication device, a noise-detecting data generation unit which generates noise-detecting data with an error detection sign to detect the noise, and a detection unit which continuously transmits or receives the noise-detecting data using at least one core line not used in the communication among core lines of the multicore cable to detect an error.
Claims8
A noise detection device connected between an end of a multicore cable and a communication device to detect a noise generated when a communication is performed between the communication devices, comprising:
- a connector used for connecting the multicore cable;
- a connector used for connecting the communication device;
- a noise-detecting data generation unit generating noise-detecting data to detect the noise;
- a data transmitting/receiving unit continuously transmitting or receiving the noise-detecting data using at least one core line not used in the communication among core lines of the multicore cable;
- a detection unit checking the received noise-detecting data to detect an error;
- and
- an optical connector connecting an optical cable to perform data communication,
- wherein the data transmitting/receiving unit includes a plurality of switchable transmission clocks, and
- wherein the data transmitting/receiving unit includes a plurality of switchable drivers/receivers.
