The Study on Tunable-SFP for Optical Transport Network for 5G Service

Abstract

With the launch of 5G services, new networks are constantly required to increase data traffic and eliminate bottlenecks. Accordingly, the optical communication network for 5G needs to continuously evolve to a high-speed, high-capacity, infrastructure to provide high-quality service. However, due to the limited number of fiber cables, the maximum capacity extension that can be transmitted is limited. To solve this problem, a new optical transport network configuration solution must be studied. Therefore, the adoption of DWDM(Dense Wavelength Division Multiplexing) scheme, which is most advantageous for increasing the data capacity among the various optical communication network technologies proposed to date, is rapidly increasing.[1] However, because DWDM is advantageous in capacity, but requires a large number of wavelengths, DWDM SFP optical module inventory per channel can accumulate, leading to an increase in inventory costs. In order to solve this problem, we applied wavelength tunable SFP(T-SFP) which can realize more than 16 channels with one SFP module and summarized the results of study on tunable SFP. © 2019 IEEE.
