Method for determining performance indicator, device and computer storage medium

An electronic device, comprising:

• a processor, and
• a memory storing a computer program executable by the processor,
• wherein the processor is configured to:
• obtain a first test result by testing preset indicators of a repeated Open Cable system in a first test environment, and obtain a second test result by testing the preset indicators of the repeated Open Cable system in a second test environment, wherein the preset indicators comprise a quality factor Q value and a linear SNR;
• determine an external SNR value of the system based on the first test result and the second test result;
• and
• determine an intrinsic SNR value of the system based on the external SNR value, the linear SNR, a nonlinear SNR, and a guided acousto-optic wave Brillouin scattering (GAWBS) SNR.

A non-transitory computer-readable storage medium with a instructions stored thereon, wherein when the instructions are executed by a processor, a method for determining a performance indicator is implemented, the method comprising:

• obtaining a first test result by testing preset indicators of a repeated Open Cable system in a first test environment, and obtaining a second test result by testing the preset indicators of the repeated Open Cable system in a second test environment, wherein the preset indicators comprise a quality factor Q value and a linear SNR;
• determining an external SNR value of the system based on the first test result and the second test result;
• and
• determining an intrinsic SNR value of the system based on the external SNR value, the linear SNR, a nonlinear SNR, and a guided acousto-optic wave Brillouin scattering (GAWBS) SNR.
