Investigation of Minimal Channel Spacing in HDWDM Systems
As WDM channel spacing continues to decrease in size, we demonstrate the minimal allowed channel spacing in HDWDM systems. According to experimental model we have created a simulation scheme in OptSim 5.0 software with the real parameters of all experimental devices. Our calculation have shown that, the minimal channel interval for 2.5 Gbit/s HDWDM system should be more than 0.2 nm, and for 10 Gbit/s system not less than 0.3 nm. These results open up new possibilities for HDWDM networks while pointing to new potential for management of optical spectrum as well as providing a limit of achievement for channel interval at different bit rates in the fiber optical network.
