Abstract
The purpose of this article is to analyze the features and formulate practical recommendations for the construction of efficient optical transport networks. To sum up the main area of application of CWDM - optical transport networks of urban and regional scale. At the same time, the costs are much lower (cheap laser diode, lack of optical amplifiers) compared to DWDM, but such a network will have fewer build opportunities due to the limited number of channels (8, max 18) and lower speeds in the optical channel. The DWDM platforms have significantly higher performance and scalability and allow you to fully realize the capabilities of optical fiber throughputs to dozens of Terabytes/sec due to the increased number of optical channels and the increase in speed in each channel. The use of multi-service transport platforms (MSTP) on the optical transport network (OTN) provides the integration of several network technologies at the hardware level and allows the creation of various network node configurations: ROADM, optic channel termination node, linear optical amplifier node, etc. When creating or upgrading OTN it is necessary to take into account: the type of optical fiber (related to the compensation of the chromatic dispersion, the presence of "water" peak of attenuation); future expansion of the network; Scalability equipment, software and hardware upgrades, build-up, component integration, port density and optical channels per board, unification of used components when building network nodes, efficient system management, and energy efficiency. The considered example of using the Cisco MSTP ONS15454 equipment demonstrates the ability to create a highly productive, scalable, versatile, efficiently managed transport network. Such transport networks and similar equipment may be used by corporations that have branching throughout the territory of Ukraine. The return on investment will increase if you attract external clients to transfer their traffic to the corporation's transport network.
