They are often used in urban areas to realize Internet surfing, Internet voice and digital TV signal transmission. They can also be used in cellular base stations. Backhaul connection, Wi-Fi hotspot communication, and even distributed antenna array. The biggest difference between the two is that the download and uplink communication protocols are different.  GPON uses wavelength division multiplexing refereed as WDM technology to make uploading and downloading at the same time. Usually, the download uses a 1490nm optical carrier, while the upload selects a 1310nm optical carrier. If you need to transmit TV signals, it will also use 1550nm optical carrier. EPON is fully compatible with other Ethernet standards, so when connected to an Ethernet- based network, no conversion or encapsulation is required, and the maximum payload is 1518 bytes.  EPON does not need to use the CSMA/CD access method in some Ethernet versions. In addition, because Ethernet transmission is the main method of local area network transmission, there is no need for network protocol conversion in the process of upgrading to a metropolitan area network. GPON Onu Device Functions The network topology of passive optical fiber transmission is mainly composed of OLT (Optical Line Terminal), ODN (Optical Distribution Network), and ONU (Optical Network Unit). ODN provides optical transmission means for OLT and ONU. It consists of passive optical splitter and passive optical combiner. It is a passive device that connects OLT and ONU. The transmission of upstream data is uniformly controlled by the OLT. The ONU transmits user data according to the time slot allocated by the OLT to avoid data transmission conflicts generated by the ONU. The ONU inserts uplink data in its own time slot according to the time slot allocation frame, which realizes the sharing of uplink channel bandwidth among multiple ONUs. Primus IT provides a variety of customized solutions, including 5g, 10g gpon to sfp, from configuration designing, programming and codingsolutions to fit our customer's gpon onu device needs.  Advantages of GPON System Technology GPON is very popular in the optical fiber market. In addition to its advanced technology, it also has the following advantages: 1. Range: Single-mode fiber can transmit data from 10 to 20 kilometers, while conventional copper cables are usually limited to a range of 100 meters. 2. Speed: The downstream transmission rate of EPON is the same as its upstream rate, which is 1.25 Gbit/s, while the downstream transmission rate of GPON is 2.48 Gbit/s. 3. Security: Due to the isolation of signals in the optical fiber, GPON is essentially a safe system. Because they are transmitted in a closed circuit and contain encryption, GPON cannot be hacked or eavesdropped. 4. Affordability: GPON optical fiber cables are cheaper than copper LAN cables, and can also avoid investment in wiring and related electronic equipment, thereby saving costs. 5. Energy saving: Contrary to the standard copper wire in most networks, the energy efficiency of GPON has increased by 95%. In addition to efficiency, Gigabit passive optical networks also provide a low-cost solution that can increase users through splitters, which is very popular in densely populated areas.

However, compared with the previous APON / BPON based on ATM technology, GEPON realizes the transmission of Ethernet frames in user access network, which is very suitable for the transmission of IP services. In addition, due to the current universal construction of IP network, the components based on Ethernet technology have relatively simple structure, high performance and low price, which makes GEPON easier to be commercialized on a large scale compared with other PON technologies; With the rapid development of various services based on IP and the trend of IP convergence of the next generation network, GEPON can be applied to a wider range, and conforms to the development trend of the future network. It has become the most important FTTH technology. GEPON Network Applications GEPON technology transmits data in the form of IP packets without protocol conversion. It can provide various WAN interfaces and connect with IP network devices. It can provide Gigabit Ethernet interface and provide switching and routing functions of IP network layer 2 and layer 3. It can provide users with data, video and telephone network interfaces. Therefore, it can support VOIP voice service, network TV service, VOD on demand service, video conference, teleconference, videophone and other services. Its characteristics and advantages will provide new opportunities for the development of various new services. GPON vs. GEPON  The meaning of GEPON is Ethernet Passive Optical Network, which is a new type of optical access network technology. GEPON is produced under the promotion of some equipment manufacturers. It aims to combine the simplest and most widely used Ethernet technology with GPON system to solve the problem of Ethernet access in a point-to-multipoint manner. GEPON technology is relatively simple, high speed and strong scalability. It can transmit signals with strong real- time requirements by sending packet signals, so as to well support TDM services. Through the transformation of GEPON system, packet signals are sent regularly in a similar TDM mode to transmit signals with strong real-time requirements, so as to well support TDM services. GPON is an operator driven solution. At the initial stage of GPON standard formulation, collect the business requirements of operators in FSAN to form a GSR (GPON business requirements) document, which is numbered g. GPON. GSR as one of the standards submitted to ITU-T. GSR document is the basis for the formation of GPON standard. In order to define a service with higher transmission rate and efficient support for a variety of services, including circuit services, according to the service requirements of operators described in GSR. The advantages of GEPON are mainly reflected in low cost and high performance. GEPON has obvious advantages in networking cost. Only one optical fiber is required between OLT and ODN. Node equipment is not required at the optical branch point. Only a simple optical brancher needs to be installed, which saves a lot of optical cable resources. The signal does not pass through the active equipment in the transmission process, so that the system has high reliability, easy maintenance and low maintenance cost. The system adopts optical passive branching technology. A single fault does not affect the operation of the whole system, with strong anti-interference ability and more stable operation. GEPON adopts tree network structure, supports multi-level connection of beam splitter, reasonable collocation of cascade beam splitter and more flexible and easy to use networking mode. At present, GEPON technology has been tested and applied at home and abroad. The GPON technology is still not very mature. At present, the publicity at home and abroad is relatively mature. Many manufacturers at home and abroad have launched GEPON solutions, and few manufacturers (about three) say they can provide GPON solutions. Although GPON technology is the optical fiber access technology expected by operators to efficiently integrate various services, the price problem is still the key for operators to be confused about this technology.

Primus IT is committed to the research and development of PON technology and provides the best solution for the realization of FTTH. Primus IT can cooperate in the development according to the special requirements of customers, and provide customers with a complete set of FTTH solutions based on a complete product line. FTTH Fiber to the Home China FTTH (Fiber to the home) is a transmission method of fiber communication. Specifically, FTTH refers to the installation of optical network units (ONU) at home users or corporate users and is the type of optical access network application that is closest to users in the optical access series except for FTTD. The notable technical feature of FTTH is that it not only provides greater bandwidth, but also enhances the transparency of the network to data formats, rates, wavelengths, and protocols, relaxes the requirements for environmental conditions and power supply, and simplifies maintenance and installation.  Advantages of FTTH technology 1. Very large transmission medium and speed and high bandwidth. 2. Its bandwidth is relatively wide, and the long distance is exactly in line with the large-scale use of operators. 3. Easy and fast installation.  4. Low-cost maintenance. 5. Low losses in network.  6. Enhance the transparency of the network to the data format, rate, wavelength and protocol. 7. Relaxed requirements on environmental conditions and power supply. 8. Increased reliability of broadband transmissions in comparison to other networks, either today or in the future. Applications of FTTH service FTTH is a comprehensive access solution for all services. Although the main driving force of FTTH is broadband video services in the future, FTTH must be able to support a variety of existing narrowband and broadband services, as well as possible new services in the future. FTTH system must be able to provide integrated access, so that users can enjoy multiple services at the same time. PON technology, especially EPON, is widely used in the access network. It promotes the simplification of the network level, makes the network structure clear, management and maintenance more convenient, and greatly reduces the cost of computer room, electricity, and maintenance. The current access network construction is widely implemented by EPON, and common networking methods include FTTB+LAN, FTTB+EOC, and even FTTH. In the past, EPON devices were mostly independent box-type devices with low port density, low capacity, and simple business functions. Now, operators mostly adopt integrated equipment that combines EPON and Layer 3 switches, especially the integration of large-capacity, multi-function switches. EPON is inserted into the chassis of the switch as a plug-in card (multiple EPON modules can be inserted), so that the OLT part of EPON and the aggregation layer switch are integrated, which further simplifies the network structure. Another advantage of this is to make business processing more flexible and convenient, such as flexible QinQ technology, VLAN three-layer termination, and even MPLS VPN services. At present, the integrated equipment with the highest business performance can provide 160 PON ports, which fully meets the operators’ high-bandwidth and large-capacity access requirements. FTTH telecom development In the optical access family, there are FTTB (Fibre To The Building) fiber to the building, FTTC (Fibre To The Curb) fiber to the roadside, FTTSA (Fibre To The Service Area) fiber to the service area, and so on.  When the optical fiber is directly connected to the user's home, there are no restrictions on its bandwidth, wavelength and transmission technology. it is suitable for the introduction of various new services. it is the most ideal service transparent network and the ultimate way for the development of access network. Although the development speed of mobile communication is amazing, because of its limited bandwidth, the terminal volume can not be too large, the display screen is limited and other factors, people still pursue the fixed terminal with relatively superior performance, that is, they want to achieve fiber to the home.  The charm of fiber to the home lies in its great bandwidth, which is the best way to solve the "last kilometer" bottleneck from the Internet backbone to the user's desktop. With the upgrading of technology, the cost of fiber to the home is greatly reduced, which will soon be comparable to DSL and HFC, which makes it possible to make FTTH practical. In addition, FTTH technology is also used to solve the "last kilometer" problem in the information superhighway. FTTH+ Ethernet is much faster than ADSL and ISDN. Primus lT is a professional ftth manufacturers, we provide ethernet transceiver, ftth in china, 10g ftth, ftth 1gb, ftth 10gb, ftth broadband speed test, interconnect etc. Want to know ftth connection cost or more?

EPON refers to an optical fiber access system. The ONU is the terminal device of the system, which can be used to connect to computers of home users and devices of industrial users. Two functions of our 10g EPON ONU: selectively receive the broadcast sent by OLT; collect and cache the Ethernet data that needs to be sent, and send the cached data to the OLT terminal according to the allocated sending window; effectively improve the uplink bandwidth utilization rate of the whole system, and configure the channel bandwidth according to the network application environment and the characteristics of applicable services; can carry as many end users as possible without affecting the communication efficiency and quality, improving the network utilization rate and reducing the user cost.    What is 10g EPON(GEPON) OLT ? EPON (Ethernet Passive Optical Network), has the characteristic of saving optical resources and is transparent to network protocols. EPON uses a single optical fiber to connect the OLT, and then the OLT connects the ONU. The 10g EPON OLT device is an important local device. It can be connected to the switch at the front end by using internet fibre 10g epon cables and connected to the optical splitter at the client end by using a single optical fiber. Fibre techno 10g epon can realize the control and management of the client device. Like the ONU equipment, it is also a photoelectric integrated equipment. EPON vs. GPON vs. 10G-EPON EPON is a kind of PON network. The EPON network consists of OLT, ODN, and ONU.  The main features are point-to-multipoint, passive line, simple and clear network layer, providing comprehensive access to voice, broadband, CATV, etc. The EPON system uses upstream and downstream symmetric transmission with a nominal rate of 1.25 GB. The STANDARD of EPON is IEEE 802.3AH, which is based on gigabit Ethernet technology and realizes PON point-to-multipoint transmission through point-to-multipoint control protocol (MPCP) on MAC layer. The protocol is simple to implement, but the OAM capability is relatively weak. While the STANDARD of GPON is ITU-T G.984 series, which follows the standard protocol framework of APON and adds GEM, a new frame encapsulation method of TC layer. It has strict regulations on QoS and OAM, and has a strong capacity to carry TDM services and relatively complex protocol.  GPON has a high transmission rate and shunt ratio, providing TDM services with high timing accuracy. As for the internet fibre techno free 10G-EPON, it is developed on the basis of EPON, and the two are basically the same in technical principle, but the free 10G-EPON has a stronger carrying capacity.
