“…As in other dispersive transmission systems, the fiber-dispersioncaused PPD can be compensated by the dispersion compensation fiber (DCF) module [7]. In the incoherent 2D FO-CDMA system, the signals have very broad bandwidth, and the dispersion compensation is difficult and expensive.…”

The effect of grating‐position deviation (GPD) and fiber dispersion in a fiber‐optic–CDMA network with a FBG encoder/decoder for incoherent 2D coding are studied here. For error‐free transmission, the GPD‐caused maximum optical pulse‐position deviation (PPD) must be below Δm, and the transmission distance must be below Lm. A modified encoder/decoder configuration is proposed to compensate for the fiber dispersion. With this proposed encoder/decoder, the user's distances in a network can be improved to L ± Lm. Error‐free transmission has been achieved through 9.5‐km SMF in the experiment with this design. © 2002 Wiley Periodicals, Inc.

“…Eight users are achieved through eight actual encoders instead of using time, polarization, or wavelength multiplexing to duplicate a lesser number of encoders. Other systems have claimed a higher number of encoders, but these fail to give an experimental bit error rate (BER) measurement of the system, and thus, the performance of such systems cannot be evaluated [9], [16]. The ability to achieve eight simultaneous encoders in our TD is a testament to our codes' resistance to MAI, and a review of these codes is given in Section II.…”

“…Optical FFH (or OFFH) is a promising 2-D coding technique to be implemented in flexible OCDMA networks with support to multirate transmissions, especially due to its practical implementation and all-optical passive signal encoding based on fiber Bragg gratings (FBGs) [55], [76]. Both frequency hopping techniques are described in more details in the next subsections.…”

“…This attractive encoding scheme stands out not only due to its good performance [40], [65] but also for its practical feasibility based on optical intensity manipulation of the incoherent signal and detection at the receiver side via IM-DD approaches. In addition to its asynchronous transmission nature, the passive all-optical encoding scheme based on MBGs implies potential low-cost and robust implementation of FFH-OCDMA (or OFFH-CDMA) networks also for multirate transmissions purposes [76].…”

Firstly, I would like to thank God for everything in life. I would like to thank my parents, Roberto Raddo and Abgail Raddo as well as my girlfriend Anne-Sophie for their constant support, love, encouragement, and total understanding during my long doctoral journey. I would like to thank Ben-Hur V. Borges, Heidi Ottevaere, Idelfonso T. Monroy, and Martin Virte for their contributions to my doctoral research as my academic advisors. I am grateful for their continuous guidance during this long and challenging path, for their helpfulness, confidence, and advice. Special thanks go to Hugo Thienpont and Heidi Ottevaere for the unique offered opportunity to develop part of the doctoral research in Brussels at B-PHOT. I would like to express my gratitude to my great friends: Israel Lot (thanks also for the book's cover), Larissa Lima (thanks also for helping me out so many times),
