Abstract:
A new two-dimensional optical code division multiple access(OCDMA)experiment system is presented in this paper. The data rate of 2.5 Gbit/s in 100 km G.652 fiber is achieved while the bit error rate (BER) is less than 10-9, even with interference user. The Gain-switched DFB laser is used as ultrashort pulse light source for encoding and decoding. A two-dimensional time-frequency domain codec is designed based on step-sampling chirp fiber grating. The encoding and decoding waveforms, with or without interfering user, are measured, and thedesirableperformanceof encodinganddecodingisobtained. Thissystemhasdemonstrated its good performance in transmission, security, reliability, anti-interference and simple structure. It provides an optimal scheme for OCDMA system, which is able to ensure security in all-optical communication and network, capacity expansion, optical code multiple access and optical code label switching.
