Power link budget calculations to determine the total allowable limits attenuation between the transmitter output power and receiver sensitivity. Power link budget calculation is done based on the ITU-T G.984 standards and regulations adopted by the PT. TELKOM is not more than 20 km and a total attenuation of 28 dB is not over.
Form of equations for the calculation of total attenuation on the link power budget as follows:

Form of equations for the calculation of the power margin is:

FTTH Access Network Configuration

FTTH Access Network Configuration
In this section we can see Configuring the GPON FTTH network using technology from STO Gegerkalong until the customer's home. Withdrawn amounts to 96 core cable is then divided into 5 ODC, ODC some of the wires used to distribute

to each of the ODP. The rest of the cable ODC pure unused stored as a backup. Then from ODP distributed back to customers homes.

Designing the Home Network Fiber To The Home Telkom Indonesia

Designing the Home Network
GPON technology has been selected to meet the needs of demand that has been predicted since it can serve a large bandwidth and GPON can also serve three services: voice, video, and data. The number of customers who are very suitable to be applied to a lot of point to multipoint networks with FTTH technology. Gegerkalong STO is about ± 3.1 km in residential Setra ambassador, this distance allows for the construction of fiber optic cable without the use of repeaters, housing his vast Setra ambassador could reach 100 hectares based layout is divided into five regions for the creation of a network, the area A, B, C, D and E. Then for withdrawal cable housing divided into 2 parts for Setra ambassador, to the A, C into one group south and regions B, D, E be a northern area. To withdrawal of fiber optic cable from STO Gegerkalong to ODC divided 2 lane splitting at the crossroads and road pollen sarimanah compassion, the first path into the area A then C, and 1 lg cable path towards B then D and then to the E.

The research process begins with a determination of the location of the problem formulation is then performed, followed by studies at the same litelatur data search. After collecting data followed by forecasting demand and then do the initial design is the manufacture and distribution of lines in residential areas Setra Bandung ambassador. Then be designed to determine the GPON technology, specifications, and volume. After GPON design, then do a feasibility analysis using the results of the network design parameters link power budget and rise time budget. And we will get the conclusion of the research.

Housing Setra Duta area located west of Bandung, bordering the city cimahi. Housing Setra ambassadors including Gegerkalong STO region, which are on the road Gegerkalong downstream. Network access is still used today uses 2 MSAN which uses optical fiber to the MSAN of STO and a 1 RK are still using copper wires. In the RAG RK has the DP (Distribution Point) as many as 43 pieces, and the capacity of as many as 480 users. MSAN MSAN MRD MRB and each has a number of DP as many as 15 pieces, and the capacity of 1 240 users MSAN. With current network conditions for housing Setraduta capacity can be served as many as 960 users.

Link Power Budget [10]
Link power budget is calculated as the requirement that the link we exceed its design limit threshold of the power needed. To calculate the power link budget can be calculated by the formula:

Demand Forecasting

Demand Forecasting
Forecasting future demand for bandwidth is an estimate of something that will happen in the future is based on the existing data in the present and the past (historical data).
Many forms of trend data. For example, in forecasting methods, there are four common forms of trend data.
1. The Linear Model
Linear trend is the trend of the data in which changes based on the time is fixed. Yt = β0 + β1T

Figure 2.8 Example Graph Linear Models
2. Quadratic Model
Quadratic trend is the trend of the data curve patterned arch (curvature). Has a quadratic trend following model: Yt = β0 + + β2T2 β1T

The advantages of GPON

The advantages of GPON
GPON excellence include:
1. Supports triple play applications (voice, data, and video) on FTTx services.
2. Providing power to the last loop.
3. Allocation of bandwidth can be set or manageable.
4. Passive component requires a lightweight and maintenence costs.
5. Process becomes simple installations and upgrades. Program GPON system device is packaged  
    in a module in order to facilitate the process instalasi.Disamping, the addition of the GPON

The components on GPON technology

The components on GPON technology were:
1. Sources of light
   The light source is used to emit light that carries information is the result of the conversion of
   electrical signals into optical signals. The light source used in GPON technology is Injection  
   Laser Diode (ILD). ILD type used in GPON systems include Fabry Perot Laser and Distributed
   feddback Laser (DFB), the spectral width of each - each 3nm and 1nm.

2. Fibre optics are used
    Type of optical fiber used in GPON applied for remote communication must have the ability to carry multiple signals at a high bit rate. Of the two types of existing optical fiber, single mode and multimode, which is used as a transmission medium GPON technology is a type of single-mode, this is because the wavelength of the working area is higher than the single mode wavelength multimode work area. So that the optical fiber type is more appropriate to use long-distance transmission that requires high-speed transmission and losses - losses small.

GPON technology

GPON is an evolution of GPON technology. There are also the stages of evolution are as follows:
1. ITU-T G.983
ITU-T G.983 is an ATM-based PON technology, supporting voice and data, efficiency of 70% f has a bandwidth of 622Mbps, adopted from ITU in 1999. Consists of Apon and BPON (ATM Passive Optical Network) is a standard PON (Passive Optical Network ) terutaman first used for business applications and using ATM technology. BPON (Broadband Passive Optical Network) is the development of Apon, this technology supports WDM and large upstream bandwidth allocation.

2. ITU-T G.984
ITU-T G.984 is a standard issued by the ITU-T GPON technology (Gigabit Passive Optical Network). GPON is an evolution of the BPON standard. This technology supports a great pace, the increase in security and a choice of 2-layer protocol (ATM, GEM, Ethernet). But in fact the ATM is not implemented. This technology has a bandwidth of 2.5 Gbps with 93% efficiency GEM (GPON Encapsulate Method) using frames segnmentation for QoS (Quality of Service) is greater. This technology allows several standard speed selection, but for the uniform industry 2.488 1.244 Mbps for downstream and upstream.

Fiber Optic Network Architecture General

Jarlokaf system has at least two (2) pieces of optoelectronic devices is 1 (one) perangkata opto-electronics at the central side and another (one) more devices on the customer side called Optical Conversion Point (TKO). The difference lies TKO Jarlokaf architecture poses different modes namely:
2.2.1 Fiber To The Zone (FTTZ)
TKO lies somewhere outside the building, both inside the cabinet with a large capacity. Customer terminals connected by TKO via copper cables up to a few kilometers. FTTZ peruahan generally applied to areas located far from the central or at the direction of the duct infrastructure is concerned, is no longer fulfilling to be added to the copper wires.

2.2.2 Fiber To The Curb (FTTC)
TKO lies somewhere outside the building, inside the cabinet and on the pole with a smaller capacity. Customer terminals connected by TKO memalui copper cables up to several hundred meters. FTTCdapat applied to business customers located gathered in a limited area but not the form of high-rise buildings or for residential customers in the near future will be the customer's entertainment services.
