Post harvest technology (PHT) is the method applied to the produce after harvest for its protection, processing, distribution, marketing, and utilization to cater the food and nutritional demands of the consumers. Post-harvest losses are very high in most of the food items including mushrooms because of high content of water. Hence, study of the post-harvest physiological processes influencing quality,...
A simple, single mode fiber/ multimode fiber (SMF-MMF) 60GHz radio over fiber scheme using a conventional central launching technique at 1550nm is experimentally evaluated under various indoor OFDM standards at a 5Gb/s bit rate.
A radio-over-fibre system using coherent optical heterodyne detection scheme is proposed, to achieve seamless integration of a photonic Remote Antenna Unit (RAU) into a Next Generation Dense Wavelength Division Multiplexed Passive Optical Network (NG DWDM-PON). The proposed scheme significantly simplifies the optical mm-wave generation and data recovery as it doesn't require any high-bandwidth modulator...
A novel, optical dispersion tolerant millimetre-wave radio-over-fibre system using optical frequency tripling technique with enhanced and selectable sideband suppression is demonstrated. 3 dB RCE penalties for multichannel WiMax transport was recorded after 40 km of fibre.
An IEEE802.16e compliant PON architecture with wavelength band overlay has been demonstrated. Transparent transmission of mobile-WiMAX RF channels over multi-wavelength GPON links, based on FDM, has demonstrated at remote receivers standard WiMAX EVM figures with 1E-11 GPON bit-error-rates.
Off-the-shelf components have been used to demonstrate, for the first time, non-intrusive C-band port discovery/alignment in arrayed-waveguide guide grating (AWG)-based access networks. MB-OFDM tones in the 3.168 to 3.696 GHz band probed AWG band edges using intrinsic VCSEL tunability.
We demonstrate simultaneous operation of FWA, FTTP and FTTCab/DSL solutions over a common passive CWDM ring network platform; verifying the potential coexistence of multiple deployment scenarios for high bandwidth delivery in future access networks.
