Only available to Ethernet ports and specifically to network management and cascading. The traffic streams of these ports, however, are isolated from each other.

In addition, the traffic streams of different VLANs are also isolated. The traffic streams in different VLANs are isolated from each other. A gateway device positioned for small office and home office SOHO users. The HGW supports routing and remote management and diagnosis. A technology that enables users to order any program in a VoD program library.

During program playing, users can perform operations, such as pause, fast forward, fast rewind, and program locating. User experience in watching a multicast program is the same as that in watching a traditional TV program. A network that uses the point-to-multipoint P2MP network architecture. It uses optical fibers to transmit data, supports more users with less optical fibers, and provides high access rates. A network that consists of optical fibers and passive optical components, such as one or more optical dividers.

Optical network terminal ONT.

How to Connect Your Olt And Configuration Olt to onu -1800-200-6122

A user terminal that provides various ports for users. Split ratio. A ratio used for dividing a downstream optical signal into sub-signals in the PON system. A greater split ratio will result in high optical power for signal transmission over the same physical distance. Fiber to the home FTTH. A type of network that provides high bandwidths for home users. User-facing provider edge U-PE.

OLT and ONT – what are their roles in GPON network?

A supplier routing device that connects to the router of a customer edge CEwhich is an OLT in this document.The EGV5 does not need to save the configuration information locally. This helps to provision services.

Run the port portid ont-auto-find command to enable the auto-find function of the ONT. After the function is enabled, you can add EGV5 according to the information reported by the system. An auto-find ONT is in the auto-find state. The auto-find ONT can work in the normal state only after it is confirmed or added. Hence, it is applicable to adding ONTs in batches. The password authentication provides two discovery modes: always-on and once-on.

This discovery mode is easy for future maintenance. In the always-on discovery mode, configuration is not required to be modified when an ONT is replaced and only the password is required. The always-on discovery mode has lower security. If other users know the password, the users will illegally have service permissions.

The once-on authentication mode has high security. After an ONT is replaced or the password is mistakenly changed, the ONT needs to be configured again, which requires more maintenance effort. Whether 24 bytes or 36 bytes are used for authentication depends on data planning, which is unified over the entire network.

If they are the same, the ONT authentication is passed. If they are the same, the ONT authentication is also passed. This operation is for compatibility with the ONTs using password authentication. Adding ONTs in offline mode is applicable to the batch deployment scenario.

When a use subscribes to the service, an installation engineer takes an ONT to the user's house and completes configurations. After the ONT goes online and passes authentication generally the password authentication mode or LOID authentication mode is usedthe service is provisioned. When users subscribe to the service, installation engineers take ONTs to the users' houses.

The procedure is as follows:. Run the snmp-profile add command to add an SNMP profile before the configuration. Run the ont snmp-route command to configure a static route for the NMS server, that is, configure the IP address of the next hop.

Run the ont alarm-profile command to bind an alarm profile. Run the gemport add command to add a GEM port.ONT web pages for configuring them have differences; however, they have the same configuration parameters. For differences on web pages, see the related ONT manuals. This scenario provides fine-grained management channels and service control, and mainly applies to Layer 3 networking. The following table describes the configuration steps. Configuring the H. The global configuration of link aggregation and queue scheduling based on priorities ensures service reliability.

The global configuration of security policies ensures service security.

Configuring the Bridging-Type ONT

GEM port ID for management services: Service profile: A service profile provides the service configuration channel for the ONT that is managed by using optical network terminal management and control interface OMCI. Alarm profile: An alarm profile contains a series of alarm thresholds to measure and monitor the performance of activated ONT lines.

When a statistical value reaches the threshold, the host is notified and an alarm is reported to the log host and the NMS.

Run the display dba-profile command to query the existing DBA profiles in the system. If the existing DBA profiles in the system cannot meet the requirements, run the dba-profile add command to add a DBA profile. Note that the sum of the fixed bandwidth and the assured bandwidth must not be greater than the total bandwidth of the PON port. After the configurations are complete, run the commit command to apply the parameters settings. After the configurations are complete, run the commit command to apply the parameters setting.

The default GPON alarm profile 1 is used. The alarm thresholds for the default alarm profile are 0, which indicates that no alarm is generated.

16 PON GPON OLT

In this example, the default alarm profile is used, and therefore the configuration of the alarm profile is not required. Run the gpon alarm-profile add command to configure a GPON alarm profile, which is used for monitoring the performance of an activated ONT line. The difference lies in this step. Here, the GPON service is used as an example.

Set the ONT IDs to 1 and 2SNs to andpasswords to anddiscovery mode for password authentication to once-onand management mode to OMCI. Add ONTs offline.

Confirm automatically discovered ONTs. Then, run the ont confirm command to confirm the ONT. If multiple ONTs of the same type bound to the same line profile or service profile are connected to the same port, you can bulk add ONTs by bulk confirming automatically discovered ONTs to make configuration easier and more efficient.

To do so, the preceding command can be modified as follows:. Optional Bind the alarm profile to the ONT. The default profile 1 is used in this example.Lets start with OLT then. 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. 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. 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.Gigabit passive optical network GPON is a point-to-multipoint access mechanism providing end users with the ability to consolidate multiple services onto a single fiber transport network.

Optical network terminal ONT is an optical modem that connects to the termination point with an optical cable. They both refer to the user side equipment in GPON network.

A small difference between them might be the application locations. ONU can work in different temperature and weather conditions. Its basic function is to control the float information in optical distribution network ODN to go in both directions.

In addition, it coordinates the multiplexing between the ONT conversion devices. There are two float directions for OLT system. One is the upstream direction to distribute different types of data and voice traffic from users. The other is the downstream direction which gets data, voice and video traffic from metro network or from a long-haul network and sends it to all ONT modules on the ODN.

If the control flag is active. You need to unbind the service first before delete the ONT. To troubleshoot the ONT, you should remember that the most important step is to connect your computer directly to the ONT to see if the problem goes away. You can use the Ethernet cable for connection.

If the problem still exists, you can reconnect the ONT power supply to clear its internal cache. If the network can not be restored after the above methods, maybe you need to consult professionals for help. COM is a good place to go. Different types of ONT and OLT equipment are provided with high integration, flexible adaption and great reliability to meet all your requirements.
