“…This frequency−multiplication technique is based on two parallel dual−drive MZMs to generate high−quality optical carrier suppression (OCS) MM−W signal. The OCS based frequency−multiplication improve R−O−F transmission systems due to its dispersion tolerance [21]. The generated optical signal can be written as…”

<span>Fifth−generation (5G) wireless networks that use the MM−W hold a great promise to revolutionize wireless industry. However, the difficulty in generating and transmitting these high‐frequency signals in the electrical−domain due to bandwidth limitation of electronic components, and high absorption loss limits current applications. Consequently, optical generation and transmission of MM−W signals are a viable option. In this paper, a comparative study is carried out on three electro−optical upconversion (EOU) techniques to generate 60−GHz MM−W signal, namely 4−tupling, 6−tupling and 8−tupling. The paper briefly describes the three techniques and analyses the optical harmonic distortion suppression ratio (OHDSR) and electrical spurious suppression ratio (ESSR) generated by each one of the techniques. OHDSR and ESSR have been compared to show the trade-off between the techniques. In addition, the paper compares the implementation of non−ideal phase shifting on OHDSR for the three EOU techniques Finally, the performance of the three EOU techniques after transmission over optical fiber is evaluated by quality factor (Q−factor) and eye pattern test. The results of the simulation illustrate well the benefits of the performed study and confirm that the 4−tupling constitutes a cost−effective technique to generate MM−W signals.</span>

During the cyclones and floods, all through the nation, the telecommunication network services were the most hit, leaving numerous individuals stripped from the ability to contact their precious ones. This paper is to demonstrate potential communications during such power blackouts. The double clad fiber is used for optically powering, transmitting and receiving the data to and from the remote antenna units by the Bidirectional method. The RoF multiband signals such as baseband, millimeter wave, and microwave, are transmitted and received bidirectionally by the single mode core, and power in outer clad to the Remote Antenna Unit. By the proposed RoF link transmission of 1 Gbps over a 100-Km DCF with an optical power of about12.0 W is achieved.bidirectional communication, double clad fibers (DCFs), power over fiber (PoF), radio over fiber (RoF), remote antenna units (RAUs) | EXPERIMENTAL ARRANGEMENT

This paper presents a new scheme of a cost-effective tunable millimeter-wave (MMW) frequency synthesizer based on an ultra-wideband electro-optic frequency comb. The architecture for the quasi-tunable millimeter-wave frequency synthesizer mainly consists of a compact ultra-wide flat electro-optic frequency comb and a multi-tone frequency generator, which only includes a quantum dot mode-locked laser, a LiNbO3 dual-driving Mach–Zehnder modulator (DD-MZM) and Uni-traveling-carrier photodiode (UTC-PD). MMW signals generated with a quasi-tunable frequency are experimentally demonstrated. The difference in power is obtained for the different frequencies. The linewidth of the quasi-tunable frequency signals is less than 273 Hz. In addition, the single side band (SSB) phase noise of the 25, 37.5, 50 and 75 GHz is measured as −115, −106, −102 and −95 dBc/Hz at an offset of 1 kHz, respectively. The proposed frequency synthesizer has ultra-low phase noise, quasi-tunable frequency and simple structure. The research results of the frequency synthesizer are applied for 5G+ transmission with radio wave working at K-band and V-band. The flexible, compact and robust MMW frequency synthesizer is suitable for the future of ultra-high capacity 5G+ communication.
