For the last few decades, fiber optic cables not only replaced copper cables but also made drastic evolution in the technology to overcome the optoelectronic bandwidth mismatch. Light trail concept is such an attempt to minimize the optoelectronic bandwidth gap between actual WDM bandwidth and end user access bandwidth. A light trail is an optical bus that connects two nodes of an all optical WDM network. In this paper, we studied the concept of split light trail and proposed an algorithm namely Static Multi-Hop Split Light Trail Assignment (SMSLTA), which aims to minimize blocking probability, the number of static split light trails assigned and also the number of network resources used, at the same time maximizing the network throughput. Our proposed algorithm works competently with the existing algorithms and generates better performance in polynomial time complexity.

Transmission Speed

The discovery of optical fiber cause widespread revolution of communication system. Optical fiber communication has excellency on data transmission speed, security, flexibility, and broadly bandwidth. The applying of WDM network can broaden the bandwidth so that the transmission performance becomes more splendid. Although some factors such as dispersion, attenuation, and scattering can hinder the performance of fiber optic on sending data. Moreover dispersion can wreck data and spread pulse as it travels alongs fiber so that causing interference. There is some methods  of dispersion compensation. In this paper, Fiber Raman Amplifier is used on WDM network to strengthen signal which is sent to detector. This research utilize simulation approachment  with various bandwidth and length fiber. The results show lowest BER value and highest Q-factor at bandwidth frequency of 30 GHz and fiber length of 20 km.
