Optical Fiber Communication System Simulation and Common Communication Interface Technology
Abstract
This paper describes the development direction of optical fiber communications, described the characteristics of system simulation and development at home and abroad. The second part is commonly used by communication interface interface discussion.

1 Outline
1.1 Optical Fiber Communication
In the information superhighway concept was put forward after the optical fiber communication technology in increasing the capacity and extend the communication distance has made rapid development. Broadband fiber amplifier W-EDFA (Wide band Erbium-Doped Fiber Amplifier) and dense wavelength division multiplexing optical fiber communication technology development is the most eye-catching direction. Loss and dispersion in order to reduce the design of the dispersion shifted fiber DSF (Dispersion Shifted Fiber), in the 1525-1565nm band, the dispersion fell to -2 - +3 ps / (nm ? km) between; zero dispersion at 1540nm. DWDM systems to reduce four-wave mixing effect, but also designed a new type of non-zero dispersion fiber NZDF (Non-Zero Dispersion Fiber). At the same time, integrated opto-electronics technologies (OEIC) is the rapid development of vertical-cavity surface-emitting laser VCSEL (Vertical Ca-vity Surface Emitting Laser) and electro-optical receiver optoelectronic integration has been achieved. Around a variety of light (OTDM) At present, there are active in research units.
1.2 System Simulation
System simulation is developed in the last two decades a science and emerging technologies. Is the so-called computer simulation model on the computer system for experimental study of the actual process. The use of computer simulation can be repeated simulation of the same phenomenon of the objective world and thus to find out the inherent laws. In particular, contain random variables and random process, it
