Upgrading Legacy Long-Haul WDM Systems Through Unbalancing the Proportion of 1s and 0s in the Transmitted Data

摘要: We present experimental results for wavelength-division multiplexed (WDM) transmission performance using unbalanced proportions of 1s and 0s in pseudo-random bit sequence (PRBS) data. This investigation simulates the effect local, time, data unbalancing which occurs some coding systems such as forward error correction when extra bits are added to WDM stream. show that local unbalancing, would practically give a time-dependent error-rate, can be employed improve legacy long-haul system if is allowed operate nonlinear power region. use recirculating loop simulate fibre system.
