A novel optical frequency-hopping system based on distributed feedback laser integrated with an electroabsorption modulator is proposed and demonstrated. In the proposed system, a user's data are split into segments and modulated onto multiple optical frequency shift keying carries, therefore, a single wavelength of optical carrier only carries partial user's data. By this way, the security of optical communication system is improved. In this paper, we demonstrate an error free transmission through 32-km single mode fiber and 8-km dispersion compensation fiber with 2.5 Gb/s hopping rate and 10 Gb/s data rate. Meanwhile, we also compare and analyze the performance of the proposed system with different hopping rate and data rate.

一种基于DFB激光器与EA调制器集成的新型光跳频系统

提出并演示了一种基于集成有电吸收调制器的分布式反馈激光器的新型光跳频系统。在所提出的系统中，用户的数据被分成段并调制到多个光频移键控载波上，因此，单个波长的光载波仅携带部分用户数据。通过这种方式，提高了光通信系统的安全性。在本文中，我们展示了通过 32 公里单模光纤和 8 公里色散补偿光纤以 2.5 Gb/s 跳频和 10 Gb/s 数据速率进行的无差错传输。同时，我们还比较和分析了不同跳频和数据速率下所提出系统的性能。
