TRANSMISI POINT TO POINTS

In the previous discussion, talk about basic characteristics of the blocks of digital fiber optic transmission link consisting of fiber optic transmission medium, optical source, photodetector, and matters relating to the receivers and connectors and how the parts are shared to form a fiber optic digital transmission link.
The first discussion about the case that sederhanan is a link point to point. The components and conditions determined through analysis of system power settings whether they fit with the terms of weakening or repeaters needed to raise the power level. The final step is to analyze the rise-time system to verify that all system requirements are met.
Here is the line-coding scheme which is suitable for digital data transmission over fiber optics. Coding scheme is used to show irregularities and excess on the digital information files to ensure the efficient timing of income and ease in monitoring the errors at the receiver.
The method is simple but very useful in the income characteristics of data transmission is the technique of eye-pattern. This method has been used for cable systems.
 
8.1 Link Point-To-Point
Transmission of the simplest is a line of point-to-point, which has a transmitter at one end and a receiver at the other end, can be seen in Figure 8-1. This type is the basis of a more complex system.
The conditions necessary to analyze the link is:
1. Desired transmission distance (or possible)
2. Data rate or bandwidth of channel
3. Bit error rate (BER)
