When matlab programming interfacial force is in matlab programming loading stage, matlab programming force follows matlab programming crushing force of nonlinear spring F1. When matlab programming interfacial force enters matlab programming unloading stage, matlab programming interface force begins to unload F2. The loading and unloading curves are shown in Fig. 3. The solid line indicates matlab programming loading curve containing elastic and plastic behaviours, while matlab programming dotted line shows matlab programming unloading curve following matlab path parallel to matlab programming elastic slope. A constant loading force was applied to matlab programming loading curves to simulate matlab programming crushing forces of different energy soaking up stages. A theoretical channel model is also derived, so one can analyze matlab programming unsafe factors influencing system performances. Simulation results show that matlab programming receiver sensitivity is enhanced 3. 4 dB and 2. 5 dB under QPSK and 8QAM, respectively, after 100 km Standard Single Mode Fiber SSMF transmission. Furthermore, matlab programming spectrum efficiency can be superior by about 50%. We propose an all optical virtual inner most network VPN system in an orthogonal frequency division multiplexing OFDM based long reach PON LR PON.
