| Abstract: | With the growth of IP services,the data traffic in optical access network and optical switch network presents significant burst characteristics.When researching optical networks,it generally uses the traditional periodic optical signal source which far from the actual situation.Therefore,an optical signal source which reflects the actual burst characteristics is needed.This paper analyzes the physical characteristics of the burst packets,proposes method of generating packets,and gives a proof of generating packets length from uniform distribution to a special probability distribution.It also analyzes the gain characteristics of optical modulation device,proposes two stages modulation method which improves the burst signal quality.Finally experimental relevant results are given. |
