Abstract Optical fiber has the great advantages of capacity and reliability. That is why network providers started to deploy FTTx (Fiber-To-The-x) optical access using various PON (Passive Optical Network) architectures. The leading technology right now is Gigabit PON (GPON). However, with increasing amount of multimedia we need to further develop existing technologies to go on with these high demands. Fiber-To-The-Home (FTTH) using 10G-PON technology for broadband access application is effective solution for high speed networks with high capacity. In this paper, we look at the passive optical network in the city of Košice and based on the real network we created simulation model of downlink of 10G-PON based FTTH with triple-play service.

The increasing demand of high speed data results into extensive enhancement on different telecommunication technologies through wireline and wireless technologies. Optical Fiber technology is being popular for fixed broadband technologies and for backhaul network data for network convergence and media device interaction. Fiber to the home (FTTH) is gaining momentum of deployments in many countries all around the world. Passive optical network (PON) utilizes point to multipoint (P2MP) topology and is becoming suitable, cost effective, and promising solutions as compared to existing copper based telecommunication infrastructure. PON architecture is cheaper than other architectures due to dynamic bandwidth allocation and common resources that can be used by different subscribers and especially for home subscribers. This paper presents a study on the effective deployment of PON based FTTH network at Nepal by referring the deployment scenario of Nepal Telecom (NT), while this network design, deployment, and implementation provides a lesson learn for cost effective deployment of such network to other stakeholders of developing countries having similar territory and implementation challenges.

AbstractWavelength-division multiplexed-passive optical network (WDM-PON) is a revolutionary high-capacity and scalable broadband access network. This paper capitalizes on Laguerre–Gaussian (LG) modes to reduce modal dispersion and increase data capacity. A data rate of 25 Gbit/s is attained for a multimode fiber link by multiplexing five LG modes on five wavelengths centered at 1,550.12 nm for a distance up to 800 m.

Migrasi dari jaringan akses tembaga menuju jaringan akses optik maupun penggelaran baru jaringan akses serat optik menjadi solusi bagi penyedia layanan telekomunikasi untuk memenuhi kebutuhan pelanggan akan layanan suara, data dan video yang terintegrasi atau triple play services. Dalam makalah ini dilaporkan analisis perencanaan jaringan akses serat optik FTTH berbasis GPON di PT Telkom pada Cluster Kruing Raya STO Banyumanik Semarang. Perencanaan jaringan berdasarkan demand pelanggan dan kelayakan jaringan yang digelar diuji menggunakan parameter Link Power Budget, Rise Time Budget dan Signal-to-Noise-Ratio (SNR). Dalam perencanaan dan penggelaran dibutuhkan satu ODC (Optical Distribution Cabinet) dan 17 ODP (Optical Distribution Pack) dengan jumlah demand sebesar 132. Hasil perhitungan parameter Link Power Budget yaitu total redaman yang dihasilkan pada user 1 sebesar 21,5276 dB sedangkan user 2 sebesar 21,5276 dB, kedua redaman ini memenuhi standar yang ditentukan oleh PT Telkom yaitu maksimal sebesar 28 dB. Parameter Rise Time Budget pada user 1 menghasilkan 0,2124 ns dan untuk user 2 sebesar 0,21221 ns. Kedua hasil tersebut masih berada di bawah batas nilai waktu sistem NRZ sebesar 0,28011 ns. Parameter SNR pada user 1 didapatkan sebesar 20,6457 dB dan user 2 sebesar 24,128 dB. Hasil tersebut memenuhi batas yang telah ditentukan oleh PT Telkom yaitu lebih dari sama dengan 20 dB.

Abstract Fiber-Wireless (Fi-Wi) networks play a crucial role in broadband wireless communication. A hybrid Fi-Wi architecture integrating Optical Code Division Multiple Access (OCDMA) based Next-Generation Passive Optical Network (NGPON) with Long Term Evolution (LTE) is proposed that can provide a higher capacity to the mobile end users, thereby achieving scalability and mobility. Maximal length sequence (M-sequence) codes of code length 31 used can support six users. A simulation study is carried out for the proposed integrated architecture considering multiple users and multiple services, and the performance is analyzed in terms of the received Bit Error Rate (BER) and Error Vector Magnitude (EVM) values. A high capacity of 160 Gbps and a spectral efficiency of 2–4 bps/Hz are achieved for the multi-user and multi-service links with six users.

Abstract A new architecture for increasing the number of simultaneous users in a hybrid system and providing a solution for the channel bottleneck problem has been designed and simulated. The 10G-TDM-OCDMA-PON system combines optical code division multiple access (OCDMA) and time-division multiplexed passive optical network (TDM-PON) techniques. The high bit rate TDM-PON system is based on a bit interleaving that uses noncontiguous order for data arranging manner, this system used to obtain ultra-high-speed data rate of 40 Gbps based on four TDM channels of 10 Gbps. The OCDMA system is based on two-dimensional single weight zero cross-correlation (2D-SWZCC) employing polarization and wavelength scheme with two orthogonal polarization angles (vertical and horizontal states). The proposed hybrid system increases the scalability by multiplexing M OCDMA codes in the same time slot of the TDM system that has N time slots. The results show that the proposed system with 2D-SWZCC has better performance with a high number of users and higher scalability than the system with 1D-SWZCC.

AbstractNowadays, bandwidth demand is enormously increasing, that causes the existing passive optical network (PON) to become the future optical access network. In this paper, next generation passive optical network 2 (NG-PON2) based, optical time division multiplexing passive optical network (OTDM-PON), wavelength division multiplexing passive optical network (WDM-PON) and time & wavelength division multiplexing passive optical network (TWDM-PON) systems with 20 Gbps (8 × 2.5 Gbps) downstream and 20 Gbps (8 × 2.5 Gbps) upstream capacity for eight optical network units has been proposed. The performance has been compared by varying the input power (−6 to 27 dBm) and transmission distance (10–130 km) in terms of Q-factor and optical received power in the presence of fiber noise and non-linearities. It has been observed that TWDM-PON outperforms OTDM-PON and WDM-PON for high input power and data rate (20/20 Gbps). Also, TWDM-PON shows its superiority for long-reach transmission up to 130 km, which is a cost-effective solution for future NG-PON2 applications.
