10 Gb/s x 2 ch signal unrepeated transmission over 100 km of data rate enhanced time-spread/wavelength-hopping OCDM using 2.5-Gb/s-FBG en/decoder

We developed data rate enhanced time-spread/wavelength-hopping optical code-division multiplexing using 2.5-Gb/s fiber Bragg grating encoder/decoder and achieved 10 Gb/s /spl times/ 2 ch signal unrepeated transmission over 100 km distance. Five-chip multiwavelength prime hop code in the 1550.4-1553.6-nm region with spacing of 0.8 nm was used.
