تکنیک های پیش پرداخت دیجیتال که امکان انتقال فرستنده های متغیر پهنای باند بالا را فراهم می کنند

Digital pre-compensation techniques are among the enablers for cost-efficient high-capacity transponders. In this paper we describe various methods to mitigate the impairments introduced by state-of-the-art components within modern optical transceivers. Numerical and experimental results validate their performance and benefits.
