Abstract

The advent of 5G mobile communications has amplified the demand for a scalable and sustainable telco networking model. Traditionally, the L-band or long band use to expand the capacity of terrestrial Dense Wavelength Division Multiplexing (DWDM) optical networks. With the acceleration of internet usage and connectivity worldwide, submarine cables carry upwards of 99 percent of global Internet traffic between continental landmasses. On-demand basis, submarine cables reaching close to Shannon’s limit which made the role for the L-band to double the maximum amount of data traffic. This paper deliberates regarding the performance of CzechLight TM (CLA) bi-directional (BiDi) Erbium Doped Fibre Amplifier (EDFA) in L-band specifically in 1595-1610 nm of 100 GHz ITU Grid with a single mode fibre transmission system. The tunable laser in this experiment finds an efficient technique to have an ultra-stable frequency gain over conventional techniques in the optical networks.
