SIMULATION IN OPTISYSTEM SOFTWARE
OptiSystem is an innovative optical communication system simulation package that designs,tests,and optimizes virtually any type of optical link from the physical layer to the transport layer according OSI model [6].OptiSystem is a stand-alone product that does not rely on other simulation frameworks.It is a system level simulator based on the realistic modeling of optic communication systems.It possesses a powerful new simulation environment and a truly hierarchical definition of components and systems.Its capabilities can be extended easily with the addition of user components,and can be seamlessly interfaced to a wide range of tools.
In this program there was created a FSO link.At the start there was CW laser with wavelength 850 nm (1550 nm) and optical power 0dBm.Pseudo-random bit sequence generator produced data which were modulated on the optical carrier wave by using external modulator.It was used NRZ modulation.This signal was transferred by the atmosphere,the FSO link length was set 1 km.At the end was placed PIN photodetector.PIN fotodetector converts optical signal back to the data.PIN photodetector was set subsequently:responsivity 1 A/W,dark current 10 nA,thermal noise 100e- 24.
Other parameters of FSO link were subsequent.Transmitter aperture diameter was 5 cm,receiver aperture diameter 10 cm,beam divergence 0.25 mrad.
The FSO component in OptiSystem allows calculate the turbulence attenuation only by Andrews’s method [6],therefore in this article there are compared the theoretical
values and measured values according Andrews’s method.It is not possible to compare other methods,because the software includes only Andrews’s method.
range of tools
RESULTS
At first it was set the wavelength 850 nm,the atmospheric attenuation coefficient 0 dB/km and the index refraction structure Cn 2 10-15 m-2/3.This low index refraction structure means very low or no turbulences.Then it was measured the optical power at the end of FSO link.The obtained value was not zero because the beam was attenuated by propagation attenuation.But the turbulence attenuation was practically
zero,because the index refraction structure was very low.The obtained received power was used as a reference value for other optical powers by varying index refraction structure parameter.The results for wavelength 850 nm are in the table
and are displayed in Fig.5.The red curve is result from OptiSystem,the blue curve are calculated values.
The same procedure was used for wavelength 1550 nm.All parameters were set the same,only the wavelength was changed from 850 nm to 1550 nm.The results for wavelength 1550 nm are in the table and are displayed in Fig.6.The red
curve is result from OptiSystem,the blue curve are calculated values.

仿真软件在optisystem
optisystem是一个创新的光通信系统仿真软件,设计,测试和优化,几乎任何类型的光学链路从物理层到传输层OSI模型[ 6].optisystem是一个独立的产品,不依靠其他仿真框架.它是一个系统级仿真器的基础上的现实的模拟通信系统.它拥有一个强大的新的仿真环境和一个真正的分级定义的元件和系统.其功能可以很容易扩展的另外用户组件,可以无缝地连接到一个范围广泛的工具.
这个计划有创建了一个自由空间光通信系统.在开始有连续激光波长850纳米(1550纳米)和光功率信号.伪随机序列发生器产生的数据进行调制的光载波使用外部调制器.它是用于非归零码调制.这个信号被转移的氛围,自由空间光通信系统的长度是1公里.在结束了光探测器.针fotodetector转换光信号返回数据.光探测器是随后响应1秋冬,暗电流为10- 24,热声冷却器100 E_.
其他参数的自由空间光通信系统,随后.发射孔径直径为5厘米,直径10厘米的接收孔径,束散角0.25弧度.
科部分optisystem允许计算湍流衰减只有安德鲁斯的方法[ 6],因此本文进行比较的理论
值和测量值,根据安德鲁斯的方法.这是不可能的,比其他方法,因为该软件只包括安德鲁斯的方法.
一系列的工具
结果
首先是850纳米的波长,大气衰减系数0分贝/公里和折射指数结构2- 15- 2/ 3.这种低折射指数结构的手段非常低或没有动荡.它是衡量光功率在年底无线光通信链路.所得到的值是不为零,因为光束是减毒的传播衰减.但实际上是紊流衰减
零,因为折射指数结构很低.所获得的接收功率是用来作为参考值为其他光学权力由不同的折射指数结构参数.结果是在波长850纳米的表
并显示在图5.红色曲线是由optisystem,蓝色曲线的计算值.
同样的程序是用于波长1550纳米.所有的参数进行设置相同,只有波长从850纳米到1550纳米.结果是在波长1550纳米的表,显示在图6.红
曲线是由optisystem,蓝色曲线的计算值
