Optical amplifiers in optical fiber communications systems

摘要

In recent years, one of the most tremendous outcomes of photonics research has been the rapid and impressive development of optical amplification, a technology that has quickly moved from the lab to practical application. The advantages of this technology are discussed. An approach to evaluate the performance of optically amplified digital fiber-optic communication links is present. The end-to-end performance of these links with lumped Erbium-doped fiber amplifier (EDFA) is described. The procedure for finding the optimized performance of remote EDFA to maximize the budget improvement is developed.
