WAVELENGTH DIVISION MULTIPLEXING TRANSMISSION SYSTEM AND APPARATUS AND OPTICAL SIGNAL NOISE RATIO CALCULATION METHOD |
摘要 |
A wavelength division multiplexing (WDM) transmission system for transmitting a wavelength division multiplexed signal light from a sender transmission apparatus to a receiver transmission apparatus is provided. The system comprises a computing unit that subtracts from a first optical signal noise ratio (OSNR) of the signal light measured by the receiver transmission apparatus a second OSNR ascribed to a sideband of the signal light measured by the sender transmission apparatus so as to compute a corrected OSNR of an amplified spontaneous emission (ASE) noise light with a reduction of an effect of the sideband.
