In this paper, we use Chi-square distribution instead of Gaussian distribution as the model of ASE noise. Irregular repeat accumulate ( IRA) codes have high performance very closed to Shannon limit. We apply IRA codes to the long haul fiber communication system.

Then, we describe the time distribution of practical overtime by chi-square distribution. After deducing the wage-output efficiency, we take it as the assessing standard of wage-pricing method, and find the optimization model with which the optimal wage-pricing is satisfied.
