Metro Optical Ethernet Solution - EODWDM advantages
EODWDM has the following advantages: Make full use of the bandwidth resources of the optical fiber, greatly improving the transmission rate.
Metro Optical Ethernet Solution - EODWDM
EODWDM uses DWDM as the transmission carrier to improve the transmission capacity of single-beam optical fiber through wavelength multiplexing. EODWDM adopts Ethernet frame format, which can be connected through end-to-end, ring or mesh. EODWDM is particularly effective in the context of high bandwidth and high efficiency, such as information storage solutions and data center interconnection. The current commercial DWDM system can support up to 32 wavelengths (each wavelength is equivalent to an OC48 or OC192 channel), and the network capac
Metro Optical Ethernet Solution - EORPR
RPR (Resilient Packet Ring) is a new type of optical fiber ring transmission technology suitable for multi-service packet transmission. It has the characteristics of dual-ring structure, dynamic bandwidth allocation, statistical multiplexing, service level support and fair access. It is the current data transmission on optical networks. An optimization technique for packages. The IEEE802.17 working group is currently standardizing RPR. The proposed standard stems from the need for high-efficiency and low-cost transmission of multi-service p
Metro Optical Ethernet Solution - EoF (Ethernet over fiber)
EoF (Ethernet over fiber) is a common and convenient optical Ethernet mode, which can support the rate of 10Mbps ~ 10Gbps, and supports point-to-point and mesh network connection. EOF is a very cost-effective and high-performance optical Ethernet solution with a transmission distance of up to 70 kilometers.
Metro Optical Ethernet Solution
Optical Ethernet technology extends the superiority of Ethernet to metropolitan area networks, providing end-to-end Ethernet connectivity without the need for multi-protocol conversion. Optical Ethernet can solve the above problems faced by the metropolitan area network, and build a new generation of broadband metropolitan area network for operators to meet the huge market demand for bandwidth.
Current State of Internet User
At present, the access methods that users can choose are basically various access methods based on copper wire, and the rate is between kbit / s and Mbit / s. It has been unable to meet the increasing needs of users. In terms of individual users, users are not only satisfied with the slow browsing of the Internet, but also applications such as VOD and Internet TV, which have higher bandwidth requirements, also attract users and content providers.
Advantages of optical Ethernet - 10
The advantages brought by the application of optical Ethernet technology also includes: Bandwidth management Optical Ethernet can implement bandwidth management at the packet level without having to designate a specific port. Operators can allocate different bandwidths according to different services, adjustable from 1 to 1000 Mbit / s (in increments of 1 Mbit /
Differences among PON, GPON, EPON and 10g-pon
Optical network relies on optical fiber and other optical hardware to form the neural network of the Internet. Outside the home or office, cables are usually connected to optical cables, which provide interconnection between data centers and optical line terminals (OLTS) at user locations. There are a variety of optical network technologies, such as passive optical network (PON) in question. → PON By definition, passive networks do not involve any active hardware. This means that only passive hardware is used to carry, combine, segment, filter or otherwise adjust the signals tr
Comprehensive understanding of APON, BPON, EPON, GPON
PON (passive optical network) is a passive optical network, which means that the ODN (optical distribution network) between OLT (optical line terminal) and ONU (optical network unit) does not have any active equipment, and only uses optical fiber and passive components. PON mainly adopts point to multipoint network structure, which is the main technology to realize FTTB / FTTH. PON technology contains a lot of content and is constantly updated iteratively. The development of xpon technology from APON and BPON to later GPON and EPON. These are simultaneous interpreting techno
Three layer routing and interface design of EPON System
With the proposal of the concept of network flattening, the converged OLT with the performance of "large capacity, few offices and high switching" can access the backbone network through an MSTP network [1]. According to the requirements of the operation Bureau, in case of internal failure of MSTP transmission network, OLT can participate in link switching and help realize network self-healing without the direct intervention of maintenance personnel. Theoretically, access network OLT, MSTP transmission network and backbone network can adopt segmented protection scheme. For example, OLT i
The warming of the optical fiber access market brings opportunities for the rapid development of the new generation of optical fiber access technology. However, the debate on whether EPON or GPON will dominate the future FTTH development has not subsided. At the 2008 optical communication forum held on May 28, relevant experts said that the development capacity of the product, the space for continuous cost decline and the scale of global use of this product will ultimately determine who can lead the future development of FTTH. Who is more suitable for technology? In f
Introduction and application of EPON optical module and GPON optical module
When it comes to PON optical module, let's first understand what PON is. PON refers to passive optical fiber network, which is an important way to carry broadband access network services. PON technology originated in 1995. Later, according to the difference between data link layer and physical layer, PON technology is gradually subdivided into APON, EPON and GPON. Among them, APON technology has been eliminated by the marke
Difference between industrial Ethernet switch and industrial EPON
In industrial communication products, industrial Ethernet switch and industrial EPON are two common products, each with its own characteristics. Today, EPON is simply compared in terms of protocol, industrialization degree and networking mode. 1. Protocol standardization The use of switches has been very mature, and the standardization of their protocols has long been completed, including underlying protocols, network redundancy protocols, management protocols, network precise clock transmission protocols, etc. the products of different manufacturers have good interoperabil
Broadband has entered the Gigabit era, and the demand for 10gpon has exploded on a large scale
By March 2019, China's optical network cities have been fully completed. It is planned to deploy Gigabit broadband networks in more than 300 cities this year to strive for the network user coverage capacity to reach 20 million. The three operators will work together "from top to bottom" to promote Gigabit home, equipment manufacturers have also produced self-developed chips, and the 10g PON industrial chain tends to be improved. In the next decade, the world PON demand will be dominated by the Asia Pacific region, especially the Chinese market. The three major operators gradually increas

Wi-Fi 6 supports all ISM frequency bands from 1 to 6 GHz and is backward compatible with multiple previous generation standards. In the case of multiple people sharing a Wi-Fi 6 router, the transmission rate of Wi-Fi 6 can be increased by 37% compared to Wi-Fi 5, and the delay can be reduced by 75%, which will significantly improve the user experience . Wi-Fi 6 also has higher requirements for the chip. While the transmission rate increases, the chip cannot generate too much heat. This requires the chip to adopt a more advanced manufacturing process to improve the power consumption of the chip
WiFi chip price has doubled by 5 times
According to news on August 11, Jiwei.com quoted a Taiwan-based Netcom chip supplier. The transaction price of Wi-Fi chips used in terminals in the third quarter has risen to around US$17, five times the price of US$3.5 last year. Today, stock-out and price increases have spread to almost the entire semiconductor industry, and the shortage of Wi-Fi module chips has been in short supply for some time.
