Multi-Format Wired and Wireless Signals over Large-Core Plastic Fibers for In-home Network

SI-POF Supporting Power-Over-Fiber in Multi-Gbit/s Transmission for In-Home Networks

“…In this application scenario, we investigate the feasibility of PoF to provide energy for an in-home IoT ecosystem. A centralized PoF system is proposed compatible with most in-home network infrastructure approaches that have been proposed and investigated [1,2,27], where energy is delivered from the residential gateway to feed the entire IoT system from specific units named central units (CU). These CUs may be devoted for different indoor applications such as wireless access points (AP) or VLC communication purposes and may include different embedded smart functionality options.…”

Latest Achievements in Polymer Optical Fiber Gratings: Fabrication and Applications

“…Moreover, Osahon et al [25] has demonstrated gigabit-per-second transmission over a short-range step-index POF using a multilevel pulse amplitude modulation (PAM-M) scheme, based on a laser diode (LD) as the optical source, which also shows successful simultaneous transmission of 16-QAM 40 MHz bandwidth wireless local area network (WLAN) and 64 quadrature amplitude modulation (QAM) long term evolution (LTE-A) bands. Among recent achievements, Forni et al [26] must be highlighted, due to their simultaneous transmission of an IEEE 02.11n 16-QAM 40 MHz bandwidth WLAN, 964 QAM LTE-A bands, and 1.7 Gb/s 4-PAM baseband signals over 50 m of 1-mm core diameter GI POF for inhome networks. Sensing is also an emerging area of POF applications under research, as stated in the extensive literature.…”

“…Bilro et al [28] presented a review paper about intensity modulation sensing, where all sensors include a light source, an optical fiber, and an optical spectrum analyzer or a photodetector when the accuracy is not so critical, such as structural health monitoring [27,29], deformation monitoring [30], medical instrument [31][32][33][34], environment monitoring [35,36], mechanical measurement [37][38][39], and chemical detection [40,41]. The second technique, based on Brillouin scattering in POFs [26], is mainly focused towards distributed sensing, such as structural health monitoring by POF strain sensor technology [42], according to the fundamental properties of Brillouin scattering in POF as reviewed by Mizuno et al [43]. The last technique, based on wavelength sensitivity grating devices, is the most promising area for POF sensing.…”

Simultaneous Radio-Frequency and Baseband Signal Transmission Over a Multimode Fiber

“…In addition, simultaneous RF and baseband signal transmission systems have attracted much attention [5]- [11], because it provides wired and wireless multi-services using a single transmitter and optical fiber. In the electrically superimposed methods [5]- [10], it is important to mitigate crosstalk between RF and baseband signals in the electrical domain, because the bandwidth of baseband signals, such as OOK and PAM-4 signals, is much broader than those of RF signals. Thus, the bit-rate of baseband signals has to be much lower than the carrier frequency of RF signals.…”
