DWDM for Fiber Optic Capacity Expansion

07-15-2019 02:56 PM CET | Media & Telecommunications

Press release from: HYC Co., Ltd

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. It helps to expand the capacity of an existing fiber optic backbones and get it ready for 5G deployments.

How do DWDM works? It combines and transmits multiple signals of 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.

Larger wavelength spacing
The most difference between CWDM and DWDM is the spacing of wavelength which causes the number of wavelength or channels that can 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 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.  DWDM allows carriers to get the most out of their valuable fiber assets.  Expansion is easy to achieve without the need to change or replace the existing network.

What is C band and L band in WDM (Wavelength Division Multiplexing)?
WDM (Wavelength Division Multiplexing) is a transmission technology that uses a single optical fiber to simultaneously transmit multiple optical carriers of different wavelengths in optical fiber communications. When the wavelength of light is different, the transmission loss in the fiber is also different. In order to reduce the fiber loss, it’s important to find the most suitable transmission wavelength. After a long period of exploration and testing, light with a

PON stands for passive optical network, which means that the ODN (optical distribution network) between the OLT (optical line terminal) and the ONU (optical network unit) does not have any active equipment, and only uses optical fibers and passive components.PON mainly uses a point-to-multipoint network structure, which is the main technology to realize FTTB / FTTH. PON technology contains a lot of content, and iteratively updated constantly. The development of xPON

WDM for Optical Fiber Capacity Expansion
WDM (Wavelength Division Multiplexing) provides an easy-to-implement solution for long-distance transmission of high-speed and large-capacity information, which would increase transmission capacity of the communication network. The traditional optical transmission method is that one fiber can only transmit one wavelength signal in a single time, while WDM transmits several wavelengths of light simultaneously over a single optical fiber. WDM mainly realizes wavelength multiplexing and demultiplexing through a combiner and a splitter. At
