The proliferation of high-bandwidth applications has created a growing interest in upgrading networks to deliver broadband services to homes and small businesses between network providers. There has to be a great efficiency between the total cost of the infrastructures and the services that can be offered to the end users. Coarse Wavelength Division Multiplexing (CWDM) is an ideal solution to the tradeoff between cost and capacity. This technology uses all or part of the 1270 to 1610 nm wavelength fiber range with optical channel separation about 20 nm. The problem in CWDM systems is that for a given reach the performance is not equal for all of transmitted channels because of the very different fiber attenuation and dispersion characteristics for each channel. In this work, by means of an Optical Communication System Design Software, we study a CWDM network configuration, for lengths of up to 100 km, in order to achieve low Bit Error Rate (BER) performance for all optical channels. We show that the type of fiber used will have an impact on both the performance of the systems and on the bit rate of each optical channel. In the study, we use both on the already laid and widely deployed singlemode ITU-T G.652 optical fibers and on the latest "water-peak-suppressed" versions of the same fiber as well as G.655 fibers. We have used two types of DML. One is strongly adiabatic chirp dominated and another is strongly transient chirp dominated. The analysis has demonstrated that all the studied fibers have a similar performance when laser strongly adiabatic chirp dominated is used for lengths of up to 40 Km and that fibers with negative sign of dispersion has a higher performance for long distance, at high bit rates and throughout the spectral range analyzed. An important contribution of this work is that it has demonstrated that when DML are used it produces a dispersion accommodation that is function of the fiber length, wavelength and bit rate. This could put in danger the quality of a system CWDM if it is not designed carefully.
