//Given data
L=5; //km - LENGTH OF FIBER LINK
Ts=10*10^(-9); //s - SOURCE RISE TIME
Dn=9*10^(-9); //s/km - INTERMODAL RISE TIME
Dc=2*10^(-9); //s/km - CHROMATIC RISE TIME
Td=3*10^(-9); //s - DETECTOR RISE TIME
Bopt=6*10^6; //Hz - REQUIRED OPTICAL BANDWIDTH
Tn=Dn*L;
Tc=Dc*L;
//Maximum permitted rise time

//Total system rise time
