DWDM for Fiber Optic Capacity Expansion

Dense wavelength-division multiplexing (DWDM) is the most popular WDM technology with telecommunications and cable companies because of its ability to handle so much data. HYC Co., Ltd offers various types of DWDM, WDM, CWDM. More info: http://www.hyc-system.com

  1. DWDM DWDM for for Fiber Fiber Optic Optic Capacity Capacity Expansion Expansion Dense wavelength-division multiplexing (DWDM) is the most popular WDM technology with telecommunications because of its ability to handle so much data. It helps to expand the capacity of an existing fiber optic backbones and get it ready for 5G deployments. and cable companies How How do different wavelengths simultaneously on the same fiber. For example, if an optical fiber has a capacity of 2.5 Gb/s, DWDM can multiplex 8 OC-48 signals into a single optical fiber, which can expand the optical fiber capacity from 2.5 Gb/s to 20 Gb/s. The common configuration is 4, 8, 16, 32 and 40 channels. Currently, because of DWDM, single fibers have been able to transmit data at speeds up to 400Gb/s. do DWDM DWDM works? works? It combines and transmits multiple signals of Larger Larger wavelength wavelength spacing The most difference between CWDM and DWDM is the spacing of wavelength which causes the number of wavelength or channels that can spacing

  2. be used. That’s the difference between “Coast” and “Dense”. CWDM channels each consume 20 nm of space. Instead of the 20 nm spacing in CWDM(equivalent to about 15 million GHz), DWDM uses either 50, 100 or 200 GHz spacing which allows many more wavelengths to be packed onto the same fiber. The common channels of CWDM are 8 to 18, while DWDM can even up to 40 channels. Long Long distance distance Compared with CWDM, DWDM is designed for long-haul transmission with its tighter wavelength spacing. With the help of EDFAs(Erbium Doped-Fiber Amplifiers) to boost the strength of the signal, DWDM systems can work over thousands of kilometers. With 5G on the way, service providers need to get the most bandwidth out of their current fiber networks. most out of their valuable fiber assets. without the need to change or replace the existing network. DWDM allows carriers to get the Expansion is easy to achieve
