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.

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 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

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

GPON technical features are mainly reflected in the transmission convergence layer. The transmission aggregation layer is further divided into a PON frame sublayer and an adaptation sublayer. The framing sublayer of GTC (GPON Transmission Convergence) completes the ODN transmission function required for the encapsulation and termination of GTC frames. The specific functions of the PON (such as ranging, bandwidth allocation, etc.) are also terminated at the framing sublayer of the PON. The gametophyte layer is invisible. The adaptation sublayer of the GTC provides an interface between the PDU and the higher layer entity. The ATM and GEM information completes the conversion of the Service Data Unit (SDU) and the Protocol Data Unit PDU at the respective adaptation sublayers. The OMCI adaptation sublayer is higher than the ATM and GEM adaptation sublayers, which identify VPI/VCI and Port-ID and complete the exchange of OMCI channel data with higher-level entities. Application of GPON in

PON (Passive OpTIcal Network). PON means that (in the optical distribution network) does not contain any electronic devices and electronic power supplies. The ODNs are all composed of passive components such as optical splitters, and do not require expensive active electronic devices. A passive optical network consists of an Optical Line Terminal (OLT) installed at the central control station and a set of associated Optical Network Units (ONUs) installed at the customer premises. The optical distribution network (ODN) between the OLT and the ONU contains optical fibers as well as passive optical splitters or couplers. PON working principle The OLT assembles the downlink services that are sent to the ONUs into frames, and sends them to multiple ONUs in a broadcast manner. That is, the optical splitters are divided into N independent signals, and each signal contains frames sent to all specific ONUs. Each ONU extracts only the frames sent to itself, and discards the frames of other

The current smart home technology mainly refers to communication or control protocols. Professionally, it mainly involves two parts: hardware interface and software protocol. In general, the market is mainly divided into wireless communication, wired communication and power carrier. Wired mode RS485 IEEE802.3 (Ethernet) EIB/KNX LonWorks X-10, PLC-BUS PLC-BUS overview CresNet, AXLink, etc. In addition to X-10, PLC-BUS, there is almost no communication technology specifically developed for the smart home industry. What is interesting is that the X-10 power line carrier technology was successfully developed as early as the 1970s. In the field of application and home automation, it was introduced and promoted in China around 2000, but the market situation has been difficult to open. The main reason why it is difficult to widely promote is that in addition to the equipment cost and people's needs, it is also the various technologies. problem. Why has power line carrier techno

According to a Business Insider study, global manufacturers will invest $70 billion in 2020 for IoT solutions . This is an increase from the $29 billion in 2015. 1.digital / networked factory Machines supporting IoT can transmit operational information to partners such as manufacturers or field engineers, which will enable operations managers and plant owners to remotely manage plant units and utilize process automation and optimization. At the same time, the digital connectivity unit will build a better command line and help determine the manager's Key Results Area (KRA). 2. Facilities management The use of IoT sensors in manufacturing equipment enables state-based maintenance alerts. There are many key machine tools that need to operate within a specific temperature and vibration range. IoT sensors can actively monitor the machine and alert when the device deviates from its specified parameters. By ensuring a defined working environment for the machine, manufacturers
