We analyzed the limits of the transmission of 40 DWDM channels at 10 Gb/s without the use of optical amplification in any part of the system. The channels are distributed between the wavelengths of 1532.7 nm (channel 1) and 1563.9 nm (channel 40). The insertion of dispersion compensating fiber (DCF) and the low input power to reduce the nonlinear effects were the strategies used to increase system performance and allow for greater range of channels transmitted. By the use of 6 km of DCF with dispersion of -250 ps/ was possible to reach the transmission distance of 116 km.
