Journal article (peer-reviewed)abstract
- This article experimentally demonstrates uncompressed high-definition video distribution in V-band (50-75 GHz) and W-band (75-110 GHz) fiber-wireless links achieving 3 m of wireless transmission in both cases. Access architecture is experimentally emulated by deploying single/multi-mode fibers. For the W-band, experimental assessment of passive and active approaches for implementation of remote antenna units is reported. The bit error rate performance of the optical and wireless channels is reported. A successful transmission of real-time uncompressed high-definition video in the V- and W-band fiber-wireless systems is demonstrated with prospects to pave the way for application-focused fiber-wireless connectivity.

Journal article (peer-reviewed)abstract
- We experimentally demonstrate multigigabit capacity bidirectional hybrid fiber-wireless systems with RF carrier frequencies at the W-band (75-110 GHz) that enables the seamless convergence between wireless and fiber-optic data transmission systems in access networks. In this study, we evaluate the transmission performances in two scenarios: a fiber-wireless access link that directly provide high-speed connections to wireless end users, and a fiber-wireless-fiber signal relay where a high capacity wireless link can be used to bridge two access fiber spans over physical obstacles. In both scenarios, we compare the transmission performances in terms of achievable wireless distances with and without using a high-frequency electrical power amplifier at the wireless transmitter. A downlink 16-Gbit/s QPSK signal and an uplink 1.25-Gbit/s ASK signal transmission over the two implementations are experimentally evaluated in terms of bit-error-rate (BER) performance. Results show that the use of the power amplifier can extend the wireless distance from similar to 1 m to over 15 m in an indoor environment with BER performance within the7% FEC threshold.

Simultaneous 60-GHz RoF transmission of lightwaves emitted by ECL, DFB, and VCSEL

Journal article (peer-reviewed)abstract
- Simultaneous 60-GHz radio over fiber upconversion and fiber transmission of lightwaves produced by an external cavity laser, a distributed feedback laser, and a C-band vertical cavity surface emitting laser are demonstrated. The 1.25-Gb/s data are transmitted concurrently on each of the lightwaves attaining a bit error rate performance <;10 -9 level. Carrier suppression of 20 dB is achieved for all three lightwaves placed in a wide wavelength range. The 10 -9 receiver sensitivity level for detection of three lightwaves falls in a <;3-db region. Reported close performance of the investigated techniques enables diversification of options for lightwave generation in millimeter-wave fiber-wireless networks.
