AbstractWith the goal of ultimate control over the light propagation, photonic crystals currently represent the primary building blocks for novel nanophotonic devices. Bloch surface waves (BSWs) in periodic dielectric multilayer structures with a surface defect is a well-known phenomenon, which implies new opportunities for controlling the light propagation and has many applications in the physical and biological science. However, most of the reported structures based on BSWs require depositing a large number of alternating layers or exploiting a large refractive index (RI) contrast between the materials constituting the multilayer structure, thereby increasing the complexity and costs of manufacturing. The combination of fiber–optic-based platforms with nanotechnology is opening the opportunity for the development of high-performance photonic devices that enhance the light-matter interaction in a strong way compared to other optical platforms. Here, we report a BSW-supporting platform that uses geometrically modified commercial optical fibers such as D-shaped optical fibers, where a few-layer structure is deposited on its flat surface using metal oxides with a moderate difference in RI. In this novel fiber optic platform, BSWs are excited through the evanescent field of the core-guided fundamental mode, which indicates that the structure proposed here can be used as a sensing probe, along with other intrinsic properties of fiber optic sensors, as lightness, multiplexing capacity and easiness of integration in an optical network. As a demonstration, fiber optic BSW excitation is shown to be suitable for measuring RI variations. The designed structure is easy to manufacture and could be adapted to a wide range of applications in the fields of telecommunications, environment, health, and material characterization.

AbstractIn this paper, comprehensive analyses of triple-clad fibers are presented. The geometry of multiple-clad fibers has been considered as a four-layer cylindrical structure. The geometry consists of a core and three claddings. We have analyzed and compared different types of triple-clad refractive index profiles on the basis of dispersion, mode distribution and propagation constant. To enhance the optical characteristics of these three fibers, we have developed a combined formulation which is applicable for single-clad, double clad and triple-clad optical fibers. In optical fibers, two or more claddings are required for dispersion shifting, dispersion flattening and other specialized applications. Thus, an analysis of design dispersion-shifted, dispersion-flattened and dispersion-compensated fibers is presented. We have used a boundary match method for evaluating propagation wave vectors and guided modes.

With the emergence of high-speed optical transmission, the pre-existing plesiochronous digital hierarchy (PDH) appeared unsuitable for achieving network synchronization, leading to the development of the synchronous optical network (SONET) and synchronous digital hierarchy (SDH) as the two equivalent standards for circuit-switched optical networks. Several bandwidth-efficient techniques were also developed to carry packet-switched data traffic over SONET/SDH networks, offering some useful data-over-SONET/SDH architectures. Subsequently, with the increasing transmission rates for SONET/SDH and Ethernet-based LANs, a convergent networking platform called optical transport network (OTN), was developed. With the ever-increasing volume of bursty data traffic, a standard for packet-switched ring networks, called resilient packet ring (RPR), was also developed for better bandwidth realization in optical fibers. In this chapter, we first present the SONET/SDH networks and the techniques for supporting the data traffic therein, followed by a description of the basic concepts and salient features of the OTN and RPR networks.

AbstractThe growth of optical technology is currently being studied extensively to meet the significant demand for bandwidth. The passive optical network (PON) solves the problem of bandwidth as it extends the optical network to individuals and businesses [Sifta R, Munster P, Krajsa O, Filka M, “Simulation of bidirectional traffic in WDM-PON networks", Brno University of Technology, ISSN 0033–2097, R. 90 NR 1/2014.]. In this paper, a comparative study is made between the WDM PON system and the CWDM PON system using two different architectures, one for the WDM PON and the other for the CWDM PON, to illustrate the appropriate technique for the PON network by increasing the Q factor and the OSNR ratio while minimizing the bit error rate (BER < 10–9). Both systems are simulated at 10 Gbps for four users of bidirectional SMF (Single Mode Fiber) fiber lengths and different powers. In order to determine the transmission performance for both systems, the link was designed for fiber lengths of 20, 30, 40, 50 and 60 km as well as for powers from −10 dBm up to 10 dBm for four users. The use of the EDFA amplifier in the WDM PON system is required in this document to minimize degradation caused by attenuation [Parkirti RDK, Singh R. Cost-efficient Colorless WDM-PON Based on RSOA for High Capacity. Int J Adv Res Comput Eng Technol (IJARCET). 2016;5]. On the contrary, in the CWDM PON system, the amplification is not essential because the wavelengths used in this system are not affected by the water peak which causes a strong attenuation of the wavelengths in the 1370–1410 nm range on optical fibers [Nazir M, Arshad F, Asif R. Design and evaluation of power budget for a bidirectional CWDM-Passive Optical Network. In: International Conference on Communication, Computing and Digital Systems (C-CODE), Islamabad, Pakistan, 04 May 2017.]. The peak of water vapor absorption is close to 1383 nm.

Optical fiber networks are currently the standard for delivering high bandwidth to customers. Various access technologies to business networks with a very high bandwidth up to access networks for buildings and individual consumers have emerged. In the area of business networks, bandwidths of 10 Gb/s have become established, while in the area of customer bandwidths of 100 Mb/s to 1 Gb/s are used. This chapter will focus on the optical network connections inside buildings. The use of optical glass fibers or/and polymeric optical fibers in different network topologies in connection to high-speed actual WIFI- technologies will be discussed.

Tumbuhnya pelanggan broadband berbasis jaringan Fiber To The Home (FTTH) ternyata dibarengi dengan banyaknya keluhan atau gangguan yang terjadi. Keluhan yang terjadi adalah lamanya waktu penyelesaian atau perbaikan gangguan dan sulitnya Teknisi masuk ke dalam rumah pelanggan saat melakukan perbaikan gangguan. Gangguan terbesar berada pada segmen antara Optical Distribution Point (ODP) dan Roset [1]. Gangguan yang terjadi pada segmen ini adalah sering terjadi putusnya kabel drop. Pada umumnya aktivitas yang dilakukan jika ada gangguan/putus kabel drop, baik itu di bagian outdoor maupun indoor proses perbaikannya kabel drop diganti mulai dari ODP sampai ke Roset. Hal ini tidak terlepas dari desain infrastruktur jaringan pelanggan FTTH [2]. Dalam desain jaringan pelanggan FTTH ini kabel drop ditarik dari port output adapter ODP yang berada di luar rumah sampai ke Roset yang berada di dalam rumah. Berdasarkan standar instalasi [3] [4] bahwa instalasi kabel drop dari ODP ke Roset harus melalui perangkat OTP. Pemasangan OTP bertujuan untuk mempermudah melokalisir gangguan dan demarkasi atau titik batas antara kabel bagian luar rumah (outdoor) dan bagian dalam rumah (indoor). Dengan dipasangnya ODP jika terjadi gangguan maka kabel yang terganggu itu saja yang dilakukan perbaikan atau penggatian dan hal ini akan menghemat/efesien dalam pemakaian kabel drop.
