Abstract
A measurement apparatus includes a creation unit that creates a table in which a value of repeatedly applied electrical noise is associated with a bit error rate occurring at the time of application of the electrical noise in an optical transmission and reception module for transmitting a bit string to itself in a predetermined transmission mode, and an estimation unit that estimates and calculates an actual device noise curve of the optical transmission and reception module, calculates a theoretical noise curve of the optical transmission and reception module using a theoretical equation for the transmission mode, estimates and calculates a noise amount of the optical transmission and reception module from a deviation between the actual device noise curve and the theoretical noise curve, and estimates and calculates optical transmission and reception characteristics of the optical transmission and reception module as actual device characteristics using the noise amount.
