An integrated OADM based on Bragg trans-reflectance in 1550 nm VCSEL optical fibre access networks
Boiyo, D.K.; Kipnoo, E.K. R.; Gibbon, T.B. (Elsevier, 2018)We experimentally demonstrate an all passive OADM using a single BGF, a pair of optical circulators and the low cost and energy efficient VCSELs. In this study, double reflection due to Bragg effect on a single fibre ... -
Reconfigurable high-speed optical fibre networks: Optical wavelength conversion and switching using VCSELs to eliminate channel collisions
KiboiBoiyo, D.; Chabata, T.V.; Kipnoo, E.K. R.; Gamatham, R.R.G.; Leitch, A.W.R.; Gibbon, T.B. (Elsevier, 2017-01)We experimentally provide an alternative solution to channel collisions through upwavelength conversion and switching by using vertical cavity surface-emitting lasers (VCSELs). This has been achieved by utilizing purely ... -
A signal impairment-aware scheme for next-gen flexible spectrum in 10 Gb/s VCSEL metro-access optical fibre networks
KiboiBoiyo, D.; Kipnoo, E.K. R.; Gamatham, R.R.G.; Leitch, A.W.R.; Gibbon, T.B. (Elsevier, 2017-07)We experimentally characterized and optimized link performance of a multi-node flexible spectrum network. The cheap and low power consuming and wavelength tunable vertical cavity surface-emitting lasers (VCSELs) have ... -
Signal monitoring and performance stability evaluation tool in a high speed optical communication network
Chabata, T.V.; KiboiBoiyo, D.; Kipnoo, E.K. R.; Gamatham, R.R.G.; Leitch, A.W.R.; Gibbon, T.B. (Elsevier, 2016)The diverse communication systems in South Africa have changed drastically over the last few years and are envisioned to continue to improve as evidenced by the deployment of high speed optical fibre networks, in both ... -
A VCSEL-based backbone extended-reach optical fibre network: Supporting up to 10 Gbps flexible access networks for Africa
Boiyo, D.K.; Gibbon, T.B.; Kipnoo, E.K. R. (2018)In this paper, using vertical cavity surface-emitting lasers (VCSELs) and Raman amplification, a low power consuming, energy-efficient and cheap technique to transmit high speed data signals over optical fibre is ...
