FTTx is a hot topic recently discussed by global operators. However, what is the best policy for deploying FTTx? Optical fiber to the node FTTN), optical fiber to the roadside FTTC) or optical fiber to the building FTTP )? What are the benefits of fiber laying at different locations? Is there an evolution plan that allows operators to gradually bring Optical Fiber closer to users and make full use of a large number of existing copper cables? The ultim

The broadband access network solution is a problem that designers always need to think carefully. So I studied how to design an optimized broadband access network solution more rationally. I will share it with you here, I hope it will be useful to you. With the development of communication technology, telecom services have evolved from voice-oriented narrowband services to voice, DATA, VIDEO, and other multimedia broadband services. To achieve multimedia communication, public telecommunications

to the use of optical fiber as the transmission media between the local terminal and the user. Optical fiber access can be divided into active and passive optical access. The main technology of the optical fiber user network is the optical fiber transmission technology. At present, the multiplexing technology of optical fiber transmission has developed rapidly, and most of them are in practical use. The most widely used optical fiber cabling technologies include TDM, WDM, OFDM, and CDM. Based o

transmission has developed rapidly, and most of them are in practical use. The most widely used Multiplexing technologies include TDM, WDM, OFDM, and CDM. Based on the depth of the optical fiber into the user, it can be divided into FTTC, FTTZ, FTTO, FTTF, FTTH and so on. Optical fiber access network structure The three system structures of the access loop are FTTN, FTTC, and FTTH. Each structure has its o

OAN, OAN can be divided into FTTC, FTTB, FTTO and FTTH types.In the FTTC structure, The ONU is set on the side of the road or the wire rod side of the box. A twisted pair copper cable is used between ONU and various users. For broadband image service, coaxial cable is used. one of the main features of FTTC is that existing copper cable facilities can still be us

building or community (FTTB/FTTC). Although optical fiber to the user (FTTH) is the fundamental solution to broadband access, but the current large-scale implementation of FTTH is not economical. At the present stage is to realize FTTB/FTTC, the transmission technology can be used by active optical access (including PDH, ATM, SDH, GE/FE, etc.) mainly, but passive optical access (PON) began to be applied. F

Residential data center): the cost of the OLT device is allocated based on the scale of 500 users, and a total of 16 OLT ports are required. FTTC + EPON + LAN We also consider placing an OLT on the local terminal, a single optical fiber (4 km) to the center data center of the residential area, and a Optical Splitter (0.8 km) to the building in the center data center of the residential area, each corridor uses a Optical Splitter (0.2 km) to access eac

. In a coverage area of around 500 optical nodes, the service can provide 60 analog radio and television channels, at least two telephones per household, and data services with a rate of at least 10 Mbps. Use its MHz ~ The 200 MHz band also provides at least MPEG-2 of on-demand TV services and other two-way telecommunications services. An important trend in the development of Wired Access networks is the integration of FTTC and HFCs, which leads to th

Broadband access technology is still quite commonly used. So I have studied the characteristics and advantages of different broadband access technologies. I would like to share with you here, hoping to help you. Broadband access technology is currently one of the most active areas of communication technology. In a telecom network, the access network connects users and business nodes to solve transmission, re-connection, and resource sharing issues. With the increase in bandwidth requirements, op

Do you know about General Ethernet Access (GEA? General Ethernet access (GEA) is a technology promoted in the UK. However, it may attract American enterprises with branches in the UK or Scotland. As general Ethernet access becomes more and more practical, it is receiving increasing attention in the UK. However, many people are not very clear about the performance, availability, and costs of this product. In short, General Ethernet Access (GEA) uses fiber-to-swap boxes (fiber to the cabinet,

good, it is a good access network structure. V. Form of Optical Fiber Access NetworkAccording to the position of the optical network unit ONU, the optical fiber access methods can be divided into the following types: FTTB optical fiber to building); FTTC optical fiber to roadside); FTTZ optical fiber to residential area); FTTH optical fiber to user); FTTO optical fiber to office); FTTF optical fiber to floor ); FTTP optical fiber to pole); FTTN optic

you want to introduce new broadband services and upgrade the system, you need to replace all the optical devices, or it is difficult to use the wavelength division multiplexing overlay scheme. 3) passive Double Star structure: This structure maintains the advantage of Optical Fiber sharing in the active Double Star structure, and replaces the active contact with the passive shard for easy maintenance, high reliability, and low cost. Because of a series of measures, the confidentiality is also g

Transfer Mode (ATM) and SDH synchronous time-division multiplexing technology are used for transmission of broadband services. The network structure is commonly seen in point-to-point, link-type, or ring-type network structures. The transmission rate ranges from 34Mbps-155Mbps. The transmission distance can be from several thousand meters to hundreds of kilometers. The DLC technology can be used to implement fiber-to-road (FTTC) and fiber-to-househol

-level services by 21% over the past year and a half, while optical fiber increased by 15% and ADSL by 17%. DSL and cable enterprises have developed new technologies, such as adsl2 + and DOCSIS 3.0, to improve network speed. In contrast, fiber development lacks new capabilities. The reason is that optical fiber has advantages, so it is not worried about threats from ADSL and cable. However, the disadvantage of optical fiber is that the deployment cost is too high. Hybrid methods have become a me

Technical features based on PON technology The PON system consists of optical circuit terminal (OLT), Optical Network Unit (ONU) and optical distribution network (ODN), which uses topological structures with dots to many points. Passive refers to all of the passive devices and optical fibers from Olt to ONU, and does no

At present, the main applications of interactive video services are as follows: Movie on demand, interactive TV news, directory browsing, distance learning, interactive advertising, interactive video games. II. structure of video-on-demand/interactive TV system VOD/Interactive TV system is a distributed multimedia system, i

construction model of optical fiber access network has become the mainstream construction model of optical fiber access network. It is a very complicated issue to see where fiber cables are going. You need to consider your bandwidth needs, existing access media, access point selection, data center, power supply, and O M, regulatory Policies and many other factors. Therefore, carriers need an integrated and full-scenario FTTx solution that can meet the requirements of CO,

). In this case, technicians must exchange equipment and perform measurement in another direction. But what should they do when they are separated by dozens of floors or thousands of meters? Obviously, if both of them have a light source and an optical power meter, they can measure both sides at the same time, the current advanced optical cable testing kit for certification testing can achieve two-way dual-wavelength testing, such as Fluke's CertiFiber and DSP Cable Testing series of FTA Optica

as HDSL, ADSL, HFCs, FTTB, and FTTC. For a variety of narrowband and broadband applications that require only copper cables as access, such as telephone, fax, 160Kbps N-ISDN, 384Kbps video conferencing systems, HDSL, ADSL, and other applications, the structured integrated cabling system in the building naturally provides better transmission quality than copper cables. For optical fiber network access, you can connect to the optical fiber network in t

future. For users who have deployed FTTC/FTTB/FTTD VDSL2. fast technology is upgraded. In FTTH Network Construction, FTTB/fttd g can also be used to obtain bandwidth equivalent to FTTH in mature community transformation environments. the fast solution greatly reduces the FTTH entry cost and activation cycle. The value of copper cables must be recognized under the idea of optical copper complementary cabling In today's long-standing coexistence of mul
