“…Graded index multimode fiber (GI-MMF) has been widely used in cost-sensitive short-reach/indoor applications such as interconnects in datacenters, local area networks (LANs), and cloud computing, where most of the installed building networks are based on OM-n (n = 1, 2, 3, 4) MMF topology (90%) for speeds (up to 10 Gb/s), short range (up to 300 m) optical networks [2]. MMFs can be easily installed and handled, on the roadmap to the "Do It Yourself" concept.…”

In this work, a simple remote heterodyne envelope detector scheme is proposed employing an O-SSB scheme for application in a converged E-PON / 60 GHz scenario. The proposed PON-60GHz wireless system topology ( Fig. 1) is discussed and an evaluation of this scheme is experimentally demonstrated including i) an OFDM 60 GHz wireless access system using indoor MMF, ordinary DFB lasers & ii) a 60 GHz wireless PON "bridge" using a VCSEL for the E-PON data. In both cases, the envelope detector scheme proves its robustness against phase/ wavelength variations while it preserves low cost and wavelength tolerance.

“…19,20 This fact also imposes a great challenge for the extension of this bandwidth dependent MMF performance and, conse-quently, it is necessary to estimate its effect over the broad-band transmission bands. Up to now, most temperature analysis are devoted to capability of uncooled laser diode to keep linearity in a wide temperature range 21,22 allowing competitive prices of the whole system.…”

Abstract. Arbitrary operating conditions, such as the temperature depen-dence in the fiber link impose a challenge for the extension of radio-over-multimode fiber techniques. Temperature impairment characterization is analyzed over the broadband transmission bands that can be present in the frequency response of multimode fiber (MMF) supporting multiple-GHz carriers delivering schemes. Experimental results show that these transmission bands are dramatically influenced by the hysteresis of heating and cooling temperature cycles, respectively. The influence of the MMF graded index exponent tolerance on frequency response at higher bands is also analyzed. And this variation can be directly attributed to environmental temperature changes that could affect the MMF link. Additionally, selective mode-launching schemes combined with the use of narrow line-width optical sources are experimentally demonstrated to enable broadband transmission, not only at short but also at middle-reach distances over MMFs.Subject terms: multimode fiber; temperature dependence; radio-over-fiber; frequency response.

“…Wireless medium, on the other hand, provides users with the ease of mobility. Thus, Fi‐Wi networks for indoors are the direction for our evolving future data communication needs . Most indoor environments are opting to adopt centralised dense deployment of WiFi APs following the Control And Provisioning of Wireless Access Point (CAPWAP) taxonomy that adopts Split MAC architecture where IEEE 802.11x functions are implemented across multiple entities instead of a single entity.…”

Ubiquitous presence of umpteen WiFi access points (AP) in indoor locations leads to massive degradation in effective data rates acquired by users. Indoor space contributes approximately 80% [1] of the data generated in today's world. Thus, radio resource management in indoor environment calls for immediate attention. Hybrid Fibre-Wireless (Fi-Wi) architecture for indoor has been proposed to combine the benefits of a huge bandwidth availability of fibre with the mobility offered by wireless access. In this paper, we propose a managed hybrid Fi-Wi indoor network. It consists of fibre infrastructure emanating from central home communication controller. Radio-over-fibre technology is used to distribute the radio signals throughout the indoor space using cell access nodes (CANs) to cover the immediate periphery inside rooms. The biggest advantage of such architecture is the ease of managing centrally the indoor radio resources for guaranteeing a better Quality of Service amongst heterogeneous user. In this paper, we model the problem of CAN to AP assignment based on downlink transmission delay experienced by users. We propose a centralised assignment method based on the reduction of overall network downlink transmission delay. Using MATLAB simulations, we show that a massive 66% reduction in the maximum downlink delay time for non-uniform distribution of heterogeneous users can be achieved. Finally, we prove the optimality of the centralised assignment algorithm using coalition game theory.
