AB  - The transport network which is the base of service to the end user always demands higher and higher
quality levels in terms of: reliability, manageability, scalability and upgradeability. Therefore, fiber-optic
transmission systems based on SDH for a long period occupied a prominent place in the transport networks
of virtually all telecom operators. However, the advent and widespread of recent telecommunication and
network services pose new demands and opportunities. New broad band services require revision of the
capacity of existing transport networks operators. The focus in this study is in the telecommunications
transport network SDH technology using wavelength division multiplexing to increase the network capacity.
The goal is also to enable complex topologies with the objective of improving the efficiency of the network and
expanding its functionality. The approach is based on the effective implementation of WDM, analysis
redundancy schemes and on redundant P-cycles. Operators are faced with the need to support multiple
generations of technology and communication. This is necessary to ensure the transmission of 2G and 3G voice
traffics and provide intensive data for new applications and Internet access with the required quality of service.
