Using a $\hbox{Si}_{3}\hbox{N}_{4}$ Ring Resonator Notch Filter for Optical Carrier Reduction and Modulation Depth Enhancement in Radio-Over-Fiber Links

IEEE Photonics Journal, 2013
Optical carrier reduction via the use of a Si3N4 ring resonator notch filter (RRNF) is proposed and experimentally demonstrated as a means for improving the modulation efficiency in 10-GHz radio-over-fiber (RoF) links.

Investigating delay of the media access control protocols for IoT‐RoF using quantum entanglement

IET Networks, Volume 13, Issue 4, Page 324-337, July 2024.
IoT‐RoF QE‐based: MAC Protocol Delay Study. Abstract One of the significant challenges of the Radio over fibre (RoF) Medium Access Control (MAC) protocol is the propagation delay. This delay can lead to serious issues, such as higher propagation delay resulting in collisions and unnecessary retransmissions.

RoF-based indoor WiMAX transmission system [PDF]

[[abstract]]In this paper, we use the radio-over-fiber (RoF) technology to extend indoor WiMAX coverage. The RoF-based indoor WiMAX experimental platform can be divided into two kinds of basic architectures: point-to-point and point-to-multipoint.
