This MSC Thesis present two projects: being one referring to Tramo Oeste
System and the other to Pará – Maranhão System, relative to link Marabá – Santa
Maria, remote pumping and Raman amplification. The MSC Thesis treats of the expansion of the transmission capacity of
Eletronorte optical system, in the Tramo Oeste. Nowadays, this system operate in
STM1 (155 Mbit/s) rate. Also it is used a new technology to elimination the repeaters station across remot pumping. This technique is based in use of remotely pumped optical amplifier across optical fibers of the OPGW (Optical Ground Wire) cable already installed in the system. This optics amplifiers are constituted only passives components part, and there add to that, it is can be accommodated in optics correction boxes that are fixed in transmission lines
towers of system to the long link being that the pump optics souces to realization of remote pumping are located and also supplied in property terminus substation. The simulation of the systems it is across of an commercial software of simulation optisystem 4.1TM . This MSC Thesis dissertation propose changes in the optical systems to increase the transmission capacity across WDM, remote
pumping to repeaterless systems and utilization of Raman amplification. It is
broached still the conception of a DWDM optical backbone that it is a technique
cooperation accord between Eletronorte and Government of Pará State, and the simulations results of these optical backbone. It is done an comparative critical
analysis of that with the projects of opticals systems of Tramo Oeste and of the
Pará – Maranhão System, relative to the link Marabá – Santa Maria.
