Özet

In this paper 40 Gb/s and 100 Gb/s Coherent optical Orthogonal Frequency Division Multiplexing (CO-OFDM) systems are studied to obtain the relation between the bit error rate (BER) and transmission link distance for a constant signal to noise ratio (SNR). Utilizing Dense Wavelength Division Multiplexing (DWDM) with 192 optical channels in C and L bands (1528.77 nm-1612.65 nm), data rates can theoretically reach up to 19 Tb/s (192au100 Gb/s) using only one optical fiber core. In this research, we selected the same data rates with the IEEE standards published by IEEE Computer Society in 2010 and 2011. Results show the performance of the CO-OFDM system at different data rates and distances for one RF carrier and one optical carrier instead of 4 optical carriers used in IEEE 802.3ba.
