Fiber to the Home (FTTH) Automation Planning, Its Impact on Customer Satisfaction & Cost-Effectiveness

The use of automated network planning systems is crucial for reducing the deployment cost and planning time of passive optical telecommunication networks. Mixed-integer linear programming (MILP) is well suited for the purpose of modeling passive optical networks; however, excessive computing times for solving large-scale problem instances render these approaches impractical. This research presented a formulation that was based on MILP. It is for the issue of optimum dimensions of fiber equipment of the FTTH optical-access network (FTTH-OANs). The key objective is to minimize the capital expenditure associated with the implementation of FTTH-OAN, i.e. the expense of passive and active tools (splices, fiber terminations, closures, cables, optical splitters, and OLT cards, etc.) site planning costs and the cost of labor needed. This formulation is installed and tested. The key results are derived from practical physical systems installed in homes.

Predicting Product Uptake Using Bass, Gompertz, and Logistic Diffusion Models: Application to a Broadband Product

In today’s competitive environment, broadband companies innovate to stay competitive, retain existing customers, and attract new customers. A recent innovative product in this industry is the deployment of the gigabit Internet service over fiber optic networks as a solution to the growing bandwidth demands from consumers. One determinant of the decision to deploy such product is the expectation of a positive return on investment (ROI) determined among others by the penetration or take rate of the product or service. Like any product, the adoption of the gigabit Internet is influenced by the reaction of customers to this innovation. Some customers are early adopters of the product while others might not be interested in higher bandwidth Internet connections or will simply adopt the product at a later time. The purpose of this paper was to identify a model that best predicts future trends in the uptake of the gigabit Internet product over fiber-to-the home (FTTH). To that effect, this study implemented three different models: Bass, Gompertz, and logistic diffusion models; analyzed their predictive abilities; and determined the best fit model in a FTTH brownfield scenario. The data used for the study were split into two sets: the first or training set was used to create the models and the second was used to validate their predicting abilities. The data analysis used the ordinary least squares (OLS) method to select the best fit model. The results suggested that while Gompertz best fitted the training data, Bass had a better forecasting power. In other words, the Bass diffusion model was best at forecasting future uptake of the gigabit Internet service, while Logistic optimistically forecasted above the take rate and Gompertz pessimistically forecasted below. These findings present various implications for researchers and practicians. For example, future research could replicate the study for different industries and products, while practicians could anticipate realistic financial results from the implementation of the findings.

<p>The development of increasingly sophisticated technology follows the needs of the community, one of them in the telecommunications world is FTTH (Fiber to the Home) which is an optical signal delivery format from the center of the provider to the homes of costumers by using optical fiber as a medium of delivery. Delivery by using this FTTH technology can save costs and provide better service to customers. The study was conducted by interview and observation methods with network objects and FTTH components belonging to Telkom Semarang and through the literature method by searching some literature. FTTH configuration starts with the ONT to rosette connected using a patchcord cable then from rosette to OTP using an indoor cable then from OTP to ODP outside the home is connected using a dropcore cable. ODP itself is the result of the distribution of distribution cables/ aerial cables leading to ODC. ODC to STO/FTM/ODF using feeder cable. FTTH network is very effective to use, because it can use triple play services (telephone, internet and IPTV) with just 1ONT/ modem at the customer s side.</p>

RoIP Compression Method in Burst Noise Upstream Environment for CATV Network

A hybrid fiber coaxial (HFC) network uses both optical fibers and coaxial cables for cable TV networks. Coaxial cables are mainly used for access networks. Recently, fiber to the home (FTTH) is being widely deployed. For cable TV companies to utilize readily deployed FTTH, legacy coax network-based customer premise equipment (CPE) such as cable modems and set top boxes may have to be replaced with fiber network based CPE. In order to reduce the expenditure incurred in this process, radio over Internet Protocol (RoIP) technology has been proposed. In the RoIP system, RF signal for coax generated by legacy CPE toward the headend is first sampled, and digitized, and then encapsulated in IP packets, which are then sent to the headend using FTTH access technologies such as passive optical network (PON). In the process of digitizing RF signal, a huge amount of data much more than the base band data is generated. So, a data compression method is required to lower the upstream bit rate maintaining the signal quality. Most compression methods are significantly degraded due to the interference caused by burst noise in the upstream link. Therefore, this paper proposes a new compression method which combines linear predictive coding (LPC), block scaling and non-linear quantization for CATV upstream links. The proposed method is demonstrated to greatly reduce the impact of burst noise while maintaining the compression performance.

Characterization of ring network protection architecture can be identified from the results of a simulation study.

Performance Analysis of ZCC-Optical-CDMA over SMF for Fiber-To-The-Home Access Network

To provide a sustainable fiber-to-the-home (FTTH), several multiplexing techniques have been developed for this purpose. The correlation features are the main obstacle behind the network performance limitation, which imposes to a high level of multiple access interference. However, the development of multiplexing techniques helps to overcome these limitations, such as optical-code division multiple access (Optical-CDMA). Optical-CDMA is considered as one of the most powerful solutions for FTTH. This paper aims to enhance FTTH network performance by applying Zero cross-correlation code (ZCC) with Optical-CDMA with maximum link single-mode fiber. In the simulation, the system performance is demonstrated in terms of bit error rate, Q-Factor and eye diagram measurements.

Effective strategies for gradual copper-to-fiber transition in access networks

In this paper, we analyze the improvements that can be achieved with the introduction of low-cost technical arrangements and devices into the present Fiber-To-The-Cabinet (FTTC) networks aiming: to support statistical multiplexing of groups of copper pairs shared among subscribers at protocol layer two, and to relay signals along the main cable. With simple calculations, we prove the bit rate per user can be increased well beyond, that achieved with present Fiber-To-The-Home (FTTH) network standards. Crosstalk performance degradation with respect to ideal case are analysed in the case of VDSL2 35b and G.fast technologies. Costs of the considered solutions are compared with those of FTTH networks. We show that in a short-medium term the low cost of investments required for updating the FTTC network can extend the life of existing copper-based networks providing at the same time a significant performance improvement with respect to the current FTTC configuration. This facilitates the smooth transition to FTTH supported by the re-investing of the acquired revenues. The solution considered in this paper moves in the direction of rendering feasible the European Gigabit Society (EGS) vision, whose objectives are extremely challenging (if not unreachable within the foreseen 2025 timeframe) with an all-fiber approach. In fact, as shown in this paper the Gigabit-ready hybrid copper-fiber approach technology provides a feasible path to significantly reduce “gigabit” deployment costs so to gradually move toward all-fiber EGS vision.

A Framework for an Energy-Efficient Bandwidth Allocation Approach through Dynamic ONTs Grouping in Flexible GPON Access Networks

The growing demands for high speed connectivity to keep pace with bandwidth intensive applications and services have spawned the idea of developing PONs with capabilities beyond those of copper and wireless-based technologies in access network. In this article, an approach for the design of an energy efficient bandwidth allocation mechanism for the shared upstream communication link in the Fiber to the Home (FTTH) access network is presented and evaluated using Mixed Integer Linear Programming (MILP) model. In the MILP model, two objective functions for minimization of power consumption and minimization of blocking were evaluated. The results have shown that with the objective of power minimization approach, Optical Network Terminals (ONTs) are efficiently grouped to the minimum number of active networking Optical Line Terminal (OLT) switches, traffic is groomed, ports are efficiently utilized, and hence total power consumption is minimized. Results have shown that with energy efficient bandwidth allocation approach consideration, energy savings can reach up to 80% for different examined traffic loads following uniform distribution.

Comparison of typical access networks with AMOOFDM based access networks

Access networks are under constant development looking for customer’s satisfaction by enhancing the internet service speed and the cost of the service. Moreover, trying to serve as many residential units as possible by extending the distance reach of the access network to cover a part of a big city or to reach a rural area in a range up to 60 km. Nowaday’s networks still experience limitations in services, coverage area, and still pricey for average customers. However, a significant percentage of these networks still using the terrestrial radio wave telecommunications to distribute the service inside or between city blocks, while others use the fiber to the home (FTTH). In this article, we are comparing the performance of the currently operated access networks to the adaptively modulated optical orthogonal frequency multiplexing (AMOOFDM) based access networks, according to the bit-rate, and the distance reach of these networks; highlighting the advantages of the AMOOFDM system using some types of the semiconductor optical amplifier (SOA) as an intensity modulator.
