FIG 3 (IMAGE) Compuscript Ltd Caption Figure 3. Summary of the communication rate. (a) The spectrum efficiency (SE) and modulation bandwidth of the proposed 8-wavelength WDM system. (b) The BER of each channel, all the BERs are lower than the 7% HD-FEC threshold. (c) Comparison in data rate with the original design. The total data rate of the proposed size-improved design device is 31.38 Gb/s. Credit OES Usage Restrictions Credit must be given to the creator.
