1.25 Gbps time domain spectral phase encoded OCDMA signal with 32-chip, 40 Gchip/s optical codes has been stealthily transmitted over public 10 Gbps WDM channel. Error-free transmission has been achieved for both the public and stealth channels.
A next generation access network becomes necessary to upgrade the systems, providing a larger dedicated bandwidth to each user. Optical code division multiple access (OCDMA) is one promising candidate for new-generation broadband multiple access technique with unique features of full asynchronous transmission, low latency access, soft capacity on demand as well as optical layer security. Recently,...
Full-duplex, asynchronous, 10Gbps DPSK-OCDMA system on same wavelength using hybrid multi-port and SSFBG en/decoder is experimentally demonstrated. Error-free (BER<10-9) transmissions for all channels of both up- (4-user) and down- (8-user) link are obtained.
We experimentally demonstrate error-free (BER<10-9) transmission of full-duplex, asynchronous, 10 Gbps x 4user DPSK-OCDMA system on same wavelength using hybrid multi-port and SSFBG en/decoder.
Data-rate flexible optical code-division multiple access (OCDMA) system with 511-chip superstructured fiber Bragg grating encoder/decoders is investigated from 622 Mb/s to 0 Gb/s. A compound data-rate OCDMA system is experimentally demonstrated for the future multiple service provisioning on demand. A new optical thresholder based on cascaded second harmonic generation and difference in frequency...
