In the gigabit era, FTTR is a new coverage option for the home network as well as another advancement in home networking technology. Optical fiber was once utilized in the living room, but it is now present in every room.
When we talk about EPON/GPON networks. One thing is sure that both are Passive Optical Network and since the power intake is zero, only end terminal required power. This is the reason why we call them Passive Optical Networks (PON). It has further sub categories depending upon the technology/standards.
By definition, TR-069 stands for Technical Report published by the Broadband Forum (formally known as DSL forum) and the latest amendment is TR-069 version-5. It basically defines the CPE WAN Management Protocol or CWMP. Initially, CWMP was developed to support broadband services providers to deploy and manage CPE (customer premises equipment) in home-based scenarios and business-oriented networks.
A vital component of GPON operations is an ONT Management Control Interface, also known as OMCI. This OMCI protocol lets service providers make applications and services that use a Passive Optical Network (PON) that include voice, video, and data. Things like the internet and video services are possible due to the relationship between GPON and the OMCI protocol.
Want to learn more about the details of GPON technology in fiber internet access? Continue reading our overview to find out more about everything related to OMCI, ONU, ONT, and OLT.
Modes of GTC:
The GTC (G-PON Transport Convergence) adopts two modes of data transportation.
Different service types are supported by different adoption methods. GEM mode can only be supported by encapsulated traffic. GTC, when combine with GEM provide bigger payload and thus it supports managing several protocols like Eth and TDM using low OH (overhead) bytes.
Types of PON Control Messages:
The ITU-PON defines two types of control messages.
Introduction to OMCI:
ONU Management Control Interface commonly known as OMCI is basically a mechanism, used by OLTs to configure, manage & Monitor ONUs. In other words, the OLT controls the ONT using the OMCI. ONT is managed by OLT with the help of OMCI in the following traits:
OMCI Main Objectives:
The OMCI protocol helps OLT to do the following tasks on ONTs:
The OMCI is an asynchronous protocol as it helps to identify OLT as Master controller and ONT and Salve controller. The OMCI protocol runs over a GEM connection which is created during ONT initialization between the ONT controller and the OLT controller. The same transport mechanism is used by the payload.
OMCI & OMCC:
OMCI Protocol Bytes are carried over OMCC (ONU Management & Control Channel) which are managed via GEM. In a way OMCC play a pivotal role in communication between ONU & OLT.
Multiple ONTs can be managed by a single OLT using multi- OMCI protocol instances over various OMCC (ONU Management & Control Channel).
OMCI connection setup & registration Process:
Upon initialization, the ONU creates a virtual OMCI T-CONT, an OMCC structure that contains an OMCI queue, a placeholder for an Alloc-ID attribute, and going beyond the definition of an ordinary T-CONT, a placeholder for an OMCI port-ID attribute.
The OLT sends a PLOAM message to ONU during activation which contains/requests the ONU ID.
ONU sets Allocate ID of the T-CONT for carrying OMCI messages. This Allocation ID must always be the same as the ONU ID which is mandatory for establishing OMCC. In case, OLT assigns the default Alloc ID, ONU should acknowledge this message without taking any action. It should not be possible to de-allocate the default Alloc – ID with an assign _ Alloc-ID.
The OLT allocates a GEM port-ID to the ONU for OMCI Protocol after ONU activation completes as described by ITU-UT G.984. This is accomplished by a configure port-ID PLOAM message. The ONU populates the OMCI port-ID attribute of the OMCC structure based on that message and responds back to the OLT with an acknowledgment.

In developed countries, nearly 85% of the population accesses the internet from home. This fact increases the need for more bandwidth.
Significantly increased bandwidth can result in slower downloads, choppy streaming, and interruptions during online activities. 10GPON technology enables consumers and businesses to avoid problems like lag and buffering.
Keep reading for a complete G PON guide and an introduction to 10GPON technology.
Fiber-optic networks work using different types of PON standards. PON stands for passive optical network. In short, it sends light through cables.
There are several PON standards. GPON is one of them.
A G PON system is a type of network that works using fiber optic technology. It gives a residence or business access to even faster high-speed internet.
GPON means Gigabit Ethernet PON. All the voice and data on GPON gets sent using ATM (Asynchronous Transfer Mode).
This method uses Ethernet for data and uses proprietary encapsulation for voice transmissions. In other words, voice and data get sent in different ways.
The equipment uses a fixed-sized cell instead of data packets that vary in size. This method is better compared to an EPON (Ethernet passive optical network). Its increased bandwidth capability improves both downstream and upstream speeds.
With a GPON framework, a passive optical distribution network (PODN) links numerous optical network terminals, or ONTs/ONUs, together. An optical line terminal (OLT) connects the ONTs in different places.
The main feature of GPON is it makes use of passive splitters in the fiber optic distribution network (ODN). In other words, one single feeding fiber from an ISP can serve many residences or businesses.
Consider an internet service provider (ISP). Your ISP sends a signal using an optical line terminal (OLT). This is the GPON starting point.
All the data services your ISP sends to your computer, phone, and TV gets sent from that point. The data moves through that single-fiber optical distribution network (ODN). It continues until it comes to a passive optical splitter.
As soon as the information reaches the splitter, the splitter breaks down the light signal into several signals. Now, those signals can go on to different ONT/ONU units in your home or establishment to give you access to services. The endpoints for the signals are the ONTs/ONUs.
This is a basic explanation. However, it provides you with a high-level understanding of how GPON architecture works. The point is that GPON has a lot of advantages that make it possible to quickly, easily, and inexpensively install fiber in a wide range of places.
10 Gbps passive optical networks (10GPONs) are a cutting-edge solution following the current-generation gigabit passive optical network (GPON) and Ethernet passive optical network (EPON) solutions. It has more bandwidth and more features than current-generation solutions.
10GPON uses a passive fiber optic tree-like infrastructure. Each end-user has a separate fiber that connects to a network node. These fibers branch out from a single one that connects to other network nodes.
The IEEE-approved standard for 10G-EPON is 802.3av. It includes 10/1 Gbps and symmetrical 10 Gbps applications.
That International Telecommunication Union (ITU) set up two standards for 10GPON in 2010. The union established them with asymmetrical and symmetrical implementations of the standards.
Asymmetrical 10GPON—or XG-PON1 on a Full-Service Access Network (FSAN) —has 10 Gbps downstream and 2.5 Gbps upstream speeds. Symmetrical 10GPON—XG-PON2 on an FSAN—has 10 Gbps both ways.
10GPON uses different wavelengths for upstream and downstream compared to GPON, so both systems can work on the same fiber. The wavelengths are 1,577nm for upstream and 1,270nm for downstream traffic.
In this way, communications service providers (CSPs) can provide GPON service to most customers. Still, they can also offer high-bandwidth 10GPON services to more expensive customers like businesses or high-density multi-dwelling units.
10G GPON is the next step in the evolution of GPON technology. Several factors led to the technological development of 10G GPON. For instance, developing new services requires more bandwidth, but GPON technology can’t meet today’s bandwidth needs.
Also, innovative access technologies on the user side need more bandwidth, so outdated GPON technology will soon have problems handling traffic. In addition, network construction costs go up when there’s a higher split ratio and a greater transmission distance, resulting in the need for an updated standard.
Let’s look at the technical aspects of each of the standards.
GPON technology is the original fiber-optic standard. It uses 1480 to 1500 nm wavelength for downstream traffic and 1490 to 1310 nm for upstream traffic. The center wavelength is 1490 nm downstream and 1310 upstream.
Meanwhile, the maximum line rate for downstream traffic is 2.488 Gbit/s, while the upstream rate is 1.244 Gbit/s. GPON has a maximum physical transmission distance of 60 km.
XG PON and XGS PON are both 10GPON technologies. They have a maximum transmission distance of 100 km.
XG PON technology uses a wavelength of 1575 to 1580 nm for downstream traffic and 1260 to 1280 nm for upstream traffic. The center wavelength is 1577 nm downstream and 1270 for upstream traffic. Meanwhile, the maximum line rate for downstream traffic is 9.953 Gbit/s, while the upstream rate is 2.488 Gbit/s.
XGS PON technology specifications are very similar to those of XG PON. It uses a wavelength of 1575 to 1580 nm for downstream traffic and 1260 to 1280 nm for upstream traffic. Also, as with an XG PON system, the center wavelength is 1577 nm downstream and 1270 upstream.
Here, however, is where the latest XGS PON equipment offers a significant benefit. It has a maximum line rate of 9.953 Gbit/s for downstream and upstream traffic.
In terms of how far a transmission can go, the split ratio, optical module size, and fiber quality all affect the distance. Also, the actual split ratio depends on the type of optical module and the length of the fiber.
The telecom industry is excited about a lot of things. These trends might include 5G, artificial intelligence, the Industrial Internet, the Internet of Things, data centers, and more.
Optical fiber access networks are an essential part of the infrastructure of the digital economy. Fiber optic cable is opening up many new possibilities for growth and development.
With 10GPON, the downstream bandwidth is four times faster than with GPON, as is the downstream bandwidth. If you want to download a Blu-ray movie, you only have to wait 40 seconds.
10GPON enables providers to sell high-bandwidth products like Blu-ray titles on the traditional home broadband market. It makes it possible to deliver the product to the average user.
As a result, average revenue will go up because companies can offer a more attractive package. This is the most apparent benefit of 10GPON.
Technical analyses show that upgrading to 10GPON can help companies make more money. It also saves companies money.
For commercial scenarios that need symmetric broadband, telecoms can use a symmetrical 10GPON to support four times as much bandwidth as a GPON.
10GPON also has a lower latency. There are already some new technologies in the industry that can even lower the latency of OLT / ONU to the microsecond level. They meet the needs of special enterprise leased lines and guarantee the SLA.
Telecoms only need to swap out the central office and terminal ONT equipment to upgrade to 10GPON. This is because there’s no need to change the ODN network. After the bandwidth increases, especially if it can support symmetrical bandwidth, it can open up more applications and generate more revenue.
Also, 10GPON doesn’t change much in terms of operation and upkeep. Service provisioning, equipment configuration, and network management are all the same as the previous PON standards, so there isn’t a lot of extra work, and labor costs can stay the same.
The architecture of the OLT platform is ready for large-scale deployment. A good OLT architecture must exist for it to work well with the network, which means it must have the capability to handle the bandwidth and performance of the network.
When you move to 10GPON, traffic will go up by more than ten times. In this scenario, the OLT must have the capability to deal with digital torrents. A traditional centralized forwarding architecture can’t meet these needs.
The cost and power consumption of the core forwarding chip can’t compete with this demand. To improve the system’s speed and reliability, decentralizing business processing to each business board relieves system bottlenecks.
We hope our brief overview has helped you see the benefits of 10GPON.

Today, with the rapid development of science and technology, the era of network data is constantly bringing forth the new. The best example is the upgrade of WIFI technology, from WIFI 4, WIFI 5, and now WIFI 6.
Let’s explore the differences between WIFI 4, WIFI 5, and WIFI 6. And what will WIFI 6 bring us?
The determinate difference between them is technology standards. As the sixth generation of WIFI technology, WIFI 6 uses the 802.11ax standard while the WIFI 4 and WIFI 5 use the 802.11 ac/n.
Based on the standard 802.11ax, there is also some technical upgrade for WIFI 6 compare to WIFI 4 & WIFI 5.
Technically, WIFI 6 can support both 2.4g and 5G bands, making it a true sixth-generation WIFI iteration standard. It will now replace the 11N and 11AC products on the market.
MU-MIMO is short for multi-user multiple-input multiple-output. MU-MIMO can completely change the way WIFI networks operate, significantly increase the total throughput and capacity of the network, and triple the Internet speed.
Target function wake-up time (TWT ) can extend battery life. The TWT function can get exactly when to wake up the WIFI radio and turn on the sleep mode, and this is how TWT helps to save electricity.
OFDMA is allowing multiple terminals to transmit data simultaneously and in parallel, without having to queue up and compete with each other, thereby increasing efficiency and reducing latency.
What WIFI 6 Can Bring Us?
WIFI 6 can provide faster data transfer speeds. It achieves speed improvements through a combination of 2.4GHz and 5GHz while adopting MU-MIMO technology to improve both upstream and downstream data transmission.
WIFI 6 can have better performance in congested environments. WiFi performance suffers when it is used in densely populated areas, where signals compete with each other. WiFi 6 uses several new technologies to improve the utility of WiFi by minimizing the impact of network congestion.
The advantages of WIFI 6 are the technology upgrade bring to us. Thus, there are more and more companies in the area of the communication industry that want to provide excellent network devices to the world. ORFA TECH is one of them.

An important way to achieve the coexistence of beauty and network quality for large houses and villas is to use MESH networking to achieve wireless expansion.
Mesh networking is relatively flexible and easy to set up, especially for users who have not deployed network cables before and who need wireless expansion in the future.
Most people may be confused about what mesh networking is. We can simply understand it from its direct meaning. In a more professional sense, it means that all nodes in the network are connected, and each node is connected to at least two other nodes, and all nodes form an overall network. Currently, Mesh networking generally supports wired Mesh, wireless Mesh, and hybrid networking.
The significant part of Mesh network is a router that supports the Mesh function. Only these mesh routers are networked, then MESH network is generated.
Features of the Wireless MESH Networking:
1. Same SSID
2. Network will be unified management
3. Easy to add nodes
4. Good roaming experience
Precautions for MESH Networking:
1. The firmware versions of all routers on the network must be the same and support the MESH function
2. The distance between routers should be as close as possible and have fewer obstacles.
3. Use the same model routers for networking
Devices Related to MESH Networking
General Switch, Network management switch that supports VLAN, and Network Cable are the part of MESH networking. However, as we know that the Mesh router is the most important part of Mesh network. According to the sales data, the current best-selling MESH router is a product combining ONU and WIFI6.
