GPON supports triple-play services, high-bandwidth, long reach upto 20kmetc. Figure 1 shows various FTTx network architectures. A single fibre from the OLT runs to a passive Optical Splitter passive means, it does not require any power to operate which is located near the users' locations.
The Optical Splitter merely divides the optical power into N separate paths to the users. The optical paths can vary between 2 to From the Optical Splitter, a single mode SM fibre strand run to each user. This is shown in figure 2. GPON adopts two multiplexing mechanisms- a in downstream direction i.
The physical layer overhead PLOu at the start of the ONU upstream burst contains the preamble which ensures proper physical layer operation of the burst-mode upstream link. The OLT may allocate as much duration as it needs in the downstream, upto and including all of the downstream frame.
Each Ethernet is mapped to a single or multiple by fragmenting GEM frames. The next section describes GPON key technologies. Type 2 and Type 3 : Both T-CONT are of guaranteed bandwidth types and mainly used for video services and data services of higher priorities. Type 4 : This T-CONT is of best-effort type and mainly used for data services such as Internet and services of low priority which do not require high bandwidth.
Because the access network is shared, ONU upstream transmissions could collide if they were transmitted at random times. This is called Ranging.Video memek abg
A grant is permission to use a defined interval of time for upstream transmission. The grant map is dynamically re-calculated every few milliseconds. DBA is a methodology that allows quick adoption of users' bandwidth allocation based on current traffic requirements and it is especially good for dealing with bursty upstream traffic.
DBA allows upstream timeslots to shrink and grow based on the distribution of upstream traffic loads. If the ONU has no traffic to send, it transmits idle frames. When an ONU has no information to send, upon receiving a grant from the OLT, it sends an idle cell upstream to indicate that its buffer is empty.
Figure 3 shows the GTC frame structures for downstream and upstream directions. The upstream GTS frame contains multiple transmission bursts. The downstream GTC frame provides the common time reference for the PON and common control signaling for the upstream.
Figure 4 shows a detailed downstream GTS frame format. The ONUs then act upon the relevant information contained therein. The Psync field indicates beginning of the frame to the ONUs.Adsense payment proof in india
The Ident field contains an 8-KHz Superframe Counter field which is employed by the encryption system, and may also be used to provide low rate synchronous reference signals.In recent years, Fiber to the Home FTTH has started to be taken seriously by telecommunication companies around the world, and enabling technologies are being developed rapidly. There are two important types of systems that make FTTH broadband connections possible.
PON has recently attracted much attention due to its low cost and high performance. First of all, it is necessary to have a brief introduction of PON. But no matter which type of PONs, they have a same basic topology structure.
In these parts, PON card and power supply support hot swap while other module is built inside. The main function of OLT is to control the information float across the ODN, going both directions, while being located in a central office.
Maximum distance supported for transmitting across the ODN is 20 km. OLT has two float directions: upstream getting an distributing different type of data and voice traffic from users and downstream getting data, voice and video traffic from metro network or from a long-haul network and send it to all ONT modules on the ODN.
ONU converts optical signals transmitted via fiber to electrical signals. These electrical signals are then sent to individual subscribers. In general, there is a distance or other access network between ONU and end user's premises. Furthermore, ONU can send, aggregate and groom different types of data coming from the customer and send it upstream to the OLT. Grooming is the process that optimises and reorganises the data stream so it would be delivered more efficiently.
OLT supports bandwidth allocation that allows making smooth delivery of data float to the OLT, that usually arrives in bursts from the customer. ONU could be connected by various methods and cable types, like twisted-pair copper wire, coaxial cable, optical fiber or Wi-Fi.
ONT is generally on customer premises. Its reach is 20 km or farther. Within the ODN, fiber optic cablesfiber optic connectors, passive optical splitters, and auxiliary components collaborate with each other. The ODN specifically has five segments which are feeder fiber, optical distribution point, distribution fiber, optical access point, and drop fiber.
The feeder fiber starts from the optical distribution frame ODF in the central office CO telecommunications room and ends at the optical distribution point for long-distance coverage. The distribution fiber from the optical distribution point to the optical access point distributes optical fibers for areas alongside it. The drop fiber connects the optical access point to terminals ONTsachieving optical fiber drop into user homes.The features of the OLT are small, convenient, flexible, easy to deploy, high performance.
It is appropriate to deploy in an compact room environment. It is a high cost performance products. Perfect integration, applied flexibility, high reliability, managing, free expansibility, group web and QoS guarantee are its features. Each EPON…. More modules can be added later as your network grows. ANM performs 2 main functions exchange and control.
Exchange part provides 2 layers of exchange functions to PON module cards, and control port gives control…. AD-net Technology GEPON range offers combination of simplicity of Ethernet with bandwidth capacity of fiber to enable cost-effective, high-speed transport.

As we see from the figure, OLT is designed for controlling more than one PON in this example it serves for four independent networks. Different service types are sent separately, but simultaneously using different wavelengths. Wavelengths are shown in the table:. Its purpose is to use optical fiber for connecting to the PON on the one side, while interfacing with customers on the other side.Feliz aniversario meme
ONT supports wide variety of interfaces, depending on requirements of customer:. Functional design and chassis configuration of ONT vary depending on customer needs and requirements. The size of it can range from simple, small box, being attached outside the house to large unit mounted inside the large office building or apartment complex.

It can also send, aggregate and groom different types of data coming from customer and send it upstream to the OLT. Grooming is the process that optimises and reorganises the data stream so it would be delivered more efficient. OLT supports bandwidth allocation that allows to make smooth delivery of data float to the OLT, that usually arrives in bursts from customer. It should resist water, winds and vandals.
For the situation when the power is off there should be an emergency battery backup. For normal case there should be a power source. ONU could be connected by various methods and cable types, like twisted-pair copper wire, coaxial cable, optical fiber or Wi-Fi. I needed those to connect my PC on the third floor to have internet access in that room, and ISP installed their modem on the first floor only.
After dropping fiber patch cables, plugged in all cables into these media converters at both sides, and link came up instantly. Was much easier than I thought! Great experience — units worked straight out of the box — just needed plug in cables and we were done. Previous Next. Lomoveishiy — Finland. Raymond — USA. Stay in touch via e-mail newsletter!
