Impact of Special Fibers on the Number of Optical Repeaters in Submarine Systems

Aiming at reducing the number of required optical repeaters in transoceanic optical systems and, consequently, capital and operating expenses, we investigate the impact of deploying special fibers, with ultra-low loss and large effective area, instead of single-mode fibers (SMF) on such systems. Analyses were carried out through numerical simulations based on back-to-back optical transmissions, co...
