Coherent radio-over-few-mode-fiber

2017 Conference on Lasers and Electro-Optics Pacific Rim (CLEO-PR), 2017
W-band coherent radio-over-few-mode-fiber transmission system is presented, featuring an optical/wireless converged MIMO DSP. Power fading of radio signals incurred by mode coupling-induced crosstalk and its mitigation technique by the mode assignment and filtering are studied.

Upgradable radio-over-fiber transport system

Optical Engineering, 2017
An upgradable radio-over-fiber (RoF) transport system is proposed based on a vertical-cavity surface-emitting laser (VCSEL)-composed wavelength selector. The passband window of the wavelength selector can be electrically adjusted to select a specific lightwave from multiple injected optical carriers and attenuate the others.

Evolution of Radio-Over-Fiber Technology

Journal of Lightwave Technology, 2019
Radio-over-fiber technology provides a simpler pathway for the distribution of wireless signals in broadband wireless networks via optical means. The technology has evolved over the last 30 years, with many challenges already overcome and with many more to address. This paper provides an overview of the technology evolutionary path of RoF with a review

DWDM aspects of radio-over-fiber

LEOS 2000. 2000 IEEE Annual Meeting Conference Proceedings. 13th Annual Meeting. IEEE Lasers and Electro-Optics Society 2000 Annual Meeting (Cat. No.00CH37080), 2002
Fixed wireless access provides an attractive option for 'last mile' delivery of broadband services in urban areas. The availability of spectrum in the millimeter-wave (mm-wave) band allows delivery of digital voice, video and data services. Optical transport may play an important role in point-to-multipoint (PMP) fixed wireless access systems by ...
