What is ONU (Optical Network Unit)

图片
When it comes to ONU (Optical Network Unit) , we first introduce PON technology. PON technology has been developed since the 1990s. ITU (International Telecommunications Union) started from APON (155 M) and developed BPON (622 M). ), and to GPON (2.5 G); at the beginning of this century, due to the widespread use of Ethernet technology, IEEE has also developed EPON technology in Ethernet technology. Currently, PON technologies for broadband access mainly include EPON and GPON. The two standards are different. The EPON uplink and downlink bandwidth is 1.25 Gbit/s, the GPON downlink bandwidth is 2.5 Gbit/s, and the uplink bandwidth is 1.25 Gbit/s. The higher bandwidth in the future will be the 10 G EPON/10 G GPON developed on EPON/GPON technology. PON is a single-fiber bidirectional optical access network using a point-to-multipoint (P2MP) structure. The PON system is composed of an optical line terminal (OLT), an optical distribution network (ODN), and an optical network unit (ONU) on

Spending on PON devices, in particular GPON OLT(Optical Line Terminal) and ONT and 10g-epon devices, remained strong in the quarter, according to Dell ‘oro’s latest q4 2018 market report on broadband access. The strength in PON, along with DOCSIS 3.1 CPE devices, helped the global optical access device market grow 8 percent year-over-year to $3.4 billion in the quarter. Dell Oro research director noted that FTTH deployment continues to grow globally, with both 2.5g GPON and 10G EPON devices achieving year-on-year sales growth, particularly in China.Growth in the telecoms sector has made up for the decline in cable companies’ deployment.Sales of xDSL equipment grew 232 percent year-over-year in the quarter and VDSL grew 13 percent year-over-year as g.ast equipment shipments increased. Overall sales of xDSL devices increased 18 percent year-on-year.

Global fiber to the home penetration rate announced that the united Arab emirates ranked first in the world

According to data from the leading industry body FTTH Board of Directors, the UAE ranked first in terms of fiber-to-the-home (FTTH) penetration among all global peers for the third consecutive year. According to the annual report of the FTTH Council, the countries with the highest penetration rate of global fiber networks are shown. The UAE's fiber-optic network coverage has surpassed Singapore, China, Korea, Hong Kong and Japan. Etihad Telecom Etisalat said the company's network is the backbone of its long-term strategy to achieve and drive digital transformation through its network. The announcement shows that it maintains a consistent leadership position in global FTTH penetration and sets the benchmark for the global telecommunications industry. This achievement is only possible thanks to the continued support and vision of the UAE leadership in the development and modernization of infrastructure. Etisalat plans to invest 4 billion dirhams in digital transformation,

Nokia released virtual OMCI to achieve multi-vendor ONU to OLT interoperability

Nokia has launched a multi-vendor ONU connectivity platform, claiming to be able to connect its OLT to each vendor's ONU. This technique makes use of the virtual ONU management control interface OMCI to achieve this interconnection, just like installing a driver on a PC. Nokia pointed out that in order to reduce the deployment cost of FTTH, telecom operators often need to purchase ONU equipment from multiple suppliers, but the ONU of these different manufacturers must be intercommunicated with OLT equipment , which may bring a lot of trouble to operators' deployment and service opening. Nokia's multi-vendor ONT connectivity platform is an open, cloud-based software platform. Based on the company's Altiplano software platform, OMCI virtualizes and has different versions that work well with OLT and ONU . This product of nokia brings true SDN/NFV convenience for FTTH operators, which can help operators greatly reduce the cost of business deployment and provide bette

Huawei released QuickODN solution in the 10G PON era

At the FTTH Conference 2019, huawei officially launched the 10G PON QuickODN solution.Through efficient planning, rapid deployment, and digital operation and maintenance, the program helps operators build a 10g-pon oriented fiber optic basic network, and lays down all-optical highway for operators with multiple services, enabling the optical fiber broadband industry( GEPON ONU OLT manufacturers ) to have a positive business cycle. Efficient planning  at the beginning of the optical fiber network construction, the investment for the first time to scientific planning and implementing thick cover and short access, a construction that is 80% ~ 100% coverage of home users and business users, enter a shortened the length of the fiber to 50 meters huawei based on multidimensional data model and experience, the introduction of AI modeling technology, find the most suitable for the customer value model of the scene, and the development of the industry leading smart grid SmartODN gauge tool,

What are the differences between EPON and GPON?

1. EPON and GPON technology EPON (Ethernet Passive Optical Network) is an Ethernet-based PON technology. It uses point-to-multipoint architecture, passive fiber transmission, and provides multiple services over Ethernet. GPON (Gigabit-Capable PON) technology is the latest generation broadband passive optical integrated access standard based on ITU-TG.984.x standard. It has many advantages such as high bandwidth, high efficiency, large coverage, rich user interface, etc. Most operators regard it as an ideal technology for achieving broadband and integrated transformation of access network services. 2. EPON and GPON rate EPON provides fixed uplink and downlink 1.25 Gbps, 8b/10b line coding, and an actual rate of 1Gbps. GPON supports multiple speed grades, can support uplink and downlink asymmetric speed, downlink 2.5Gbps or 1.25Gbps, uplink 1.25Gbps or 622 Mbps.According to actual needs, the uplink and downlink rates are determined, and the corresponding optical modules are select
