The channel between transmitter and receiver is the most important part of the optical fiber networks like LAN, FTTH, EPON, NBN, OTN etc. So, in order to make successful communication, it is important to think what amount of signal is transmitted and how long it is transmitted through the fiber. Now the role of Frequency range of optic signal with the Optimisation tools in broadband communication for long haul transmission is to be discussed. Finally, it is said that the optical fiber network will appears as the backbone of 5th generation communication completely by the elimination of several limitations (nonlinearities) like, Cross Phase Modulation (XPM).
