Field trial of time-spreading and wavelength-hopping OCDM transmission using FBG en/decoders.

In this paper, field trial on optical code division multiplexing through the commercial-used fiber line is presented. We fabricated fiber Bragg grating en/decoders with time-spreading and wavelength-hopping scheme, considering environmental fluctuation of transmission fiber. 200 km-long transmission of 2-channel x 10 Gb/s signals was achieved on the field photonic network test bed of JGN II. Error free transmission was demonstrated in real field deployed single-mode transmission fiber.
