Demonstration of Hybrid Using ±π/2- and 0/π-Phase-Shifted SSFBG En/decoders in the 4×10Gbit/s OCDMA system
Fiber optics communications Fiber Bragg gratings Optical security and encryption
2015/5/26
We develop the novel ±π/2-phase-shifted SSFBG en/decoders (31-chip 640Gchip/s)and verify the improved security performance. We also demonstrate the mixed use of 0/π- and ±π/2-phase-shifted SSFBG en/de...
Electrically Processed OCDMA System Based on Spatial Coding and Subcarrier Multiple xing
Electrically Processed OCDMA System Spatial Coding Subcarrier Multiple xing
2016/12/2
A low-cost electrically processed OCDMA system based on spatial coding and subcarrier multiplexing is proposed. The simulation shows that at least 10 simultaneous users can be supported in a 16-code O...
Bit error rate (BER) performance of return-to-zero and non-return-to-zero data signals optical code division multiple access (OCDMA) system based on AND detection scheme in fiber-to-the-home (FTTH) networks
spectral amplitudes coding – optical code division multiple access detectionscheme subtraction technique non-return-to-zero (NRZ) and return-to-zero (RZ) pulse generator
2011/5/5
In this paper, we will focus on the modulation format used to create the optical pulses, which are
return-to-zero (RZ), and non-return-to-zero (NRZ). Bit error rate (BER) performance is evaluated

Impact of Crosstalk in Capacity performance of WDM/OCDMA System
Fiber optics communications Networks
2015/6/4
The capacity of WDM/OCDMA system is analyzed under time-wavelength domain crosstalk to determine the simultaneous capacity threshold. The system’s crosstalk, channel spacing and datarate are optimized...
8x8 Full-duplex Demonstration of Asynchronous, 10Gbps, DPSK- OCDMA System using Apodized SSFBG and multi-port En/Decoder
8x8 Full-duplex Demonstration DPSK- OCDMA System Apodized SSFBG multi-port En/Decoder
2015/7/16
We develop a novel apodized, 16-level-phase-shifted SSFBG encoder/decoder, which can improve the system performance of OCDMA system. Error free (BER<10 -9 ) transmissions of 8x8 full-duplex, asynchron...
