“…By using a fiber to connect centralstation (CS) with multiple remote simplified base-stations (BS), it can considerably increase the network capacity, coverage and mobility and furthermore serve both fixed and mobile end users [2]. Recently, many investigations have been done about the RoF system and most of them are mainly focused on the overall architecture design, the RF signal generation or the crosstalk reduction [3][4][5]. Since security is one of the most important performance indexes of a system, it is of great urgency and significance to improving the security of the RoF system.…”

Abstract. In this paper, the performance of OCDMA coding systems utilizing the radio over fiber (RoF) technique is presented. It has been done by means of conventional OptiSystem simulation tools, where the propagation of radio signals up to 50 km using standard single mode fiber (SMF) was investigated. The analysis was made based on the performance of eye diagram, bit rate, bit error rate and optical received power.

“…On the other hand, PON system is conventionally used to distribute Gbps baseband signal from the optical line termination (OLT) to the optical network unit (ONU). Several RoF works have been carried out with the intention to combine with PON system [1][2][3] later to share the wired and wireless services simultaneously. Nevertheless, there is only a portion of customer who will subscribe for both services at the same time.…”

Selective delivery of gigabit-per-second wireless and wired services is demonstrated in an integrated fiber-wireless access network using the millimeter-wave (mm-wave) radio-over-fiber (RoF) system employing the dual-sideband optical carrier suppression technique. A dual-electrode Mach-Zehnder modulator is used in this technique to generate 40 GHz carrier to distribute 1.25 Gbps data via direct modulation (DM) over a 20 km RoF system. The results show that selective signal delivery can be achieved using a low-cost DM laser diode drive current of 20 mA. The advantage of the proposed system is that it provides versatility to control the gigabit-per-second (Gbps) signal delivery in an integrated ROF-PON system with a common high frequency oscillator shared for the whole system. ABSTRACT: In "A Wideband Ultrathin Low Profile MetamaterialMicrowave Absorber" published in the 57th volume of Microwave and Optical Technology Letters, the authors come to the conclusion that the proposed structure can realize a broadband absorber, which we cannot agree with. In our opinion, it should be cross-polarization reflection rather than absorption.

“…Research is being currently done at TM Research and Development to implement radio-over-fiber (RoF) as a complementary technology to FTTH in order to minimize the issues mentioned previously (Fig. 2) [1]. Highfrequency (40 GHz) wireless links eliminate physical connections between the ISPs' access points and homes.…”

A 40 GHz power amplifier (PA) driver for the remote antenna unit (RAU) transceiver of a radio-over-fiber (RoF) system is presented in this paper. RoF is proposed as a complementary solution to fiber-to-the-home (FTTH) in order to minimize costs as well as ease accessibility. CMOS is proposed as a low cost technology for implementing the RF portion of the RAU. The PA driver is designed using a 0.13um CMOS process and the architecture used is common-gate and utilizes 50 Ohm transmission lines and metal-finger capacitors. Measurements show that the PA driver has input and output reflection coefficients that are lower than -10 dB for frequencies between 40 and 42.5 GHz. Gain is 2.1 dB and output P1dB is 10.9 dBm. The PA driver is unconditionally stable for frequencies over 4.66 GHz up to 50 GHz.
