Abstract:
An optical signal measurement method includes: measuring a power p i  of a first optical signal on a target frequency band at a moment Ti, and measuring a power q i  of a second optical signal on the target frequency band at a moment Ti+Δt, where the first optical signal is a signal detected in an optical signal transmission source, the second optical signal is a signal detected on a to-be-measured node, and Δt is a transmission duration of transmitting an optical signal from the optical signal transmission source to the to-be-measured node. The method further includes determining an optical signal-to-noise ratio on the to-be-measured node based on a power array P=[p 1 , p N ] of the first optical signal on the target frequency band and a power array Q=[q 1 , q N ] of the second optical signal on the target frequency band.

Claim (Index 9):
The device according to  claim 8 , wherein the processor is further configured to perform a correlation operation on the power array P=[p 1 , p N ] and the power array Q=[q 1 , q N ] by:\n calculating the CCA parameter for the first optical signal and the second optical signal on the target frequency band as: \u03c1 = E \ue8a0 ( PQ ) E \ue8a0 ( P 2 ) \ue89e E \ue8a0 ( Q 2 ) , wherein E(PQ)=\u03a3 (p i \u00d7q i ), E(P )=\u03a3 (p i \u00d7p i ), and E(Q )=\u03a3 (q i \u00d7q i ); and calculating the optical signal-to-noise ratio on the to-be-measured node using the CCA parameter as: O = \u03c1 2 1 - \u03c1 2 .
