How does home broadband fiber enter the home? How is the network cable selection, networking?

The question involves broadband access technology, integrated cabling, network topology and equipment selection in four areas, I will try to succinctly and popularly explained one by one.

Home broadband access

As the traditional DSLAM (Digital Subscriber Line Access Multiplexer) technology has been unable to adapt to the current large bandwidth, high stability of broadband demand, at present, China generally use PON (Passive Optical Network) technology for home broadband access, because of its use of optical fiber instead of cable (home) access, and thus in the network bandwidth, transmission distance and anti-jamming and other aspects. Has gained a qualitative leap.

Integrated wiring

The so-called integrated wiring system refers to a certain standard, specification and arrangement of various systems within the building communication lines, generally including network, telephone and monitoring systems.

Integrated cabling for home networks mainly consider the physical line (cable, fiber optic) selection, due to the current gigabit broadband has been the trend, generally applicable to 100M network in the category V, super Category 5 cable has been unable to meet the long-term needs of the family, in the family pre-built network lines should be preferred category VI (CAT.6) or higher models of cable, of course, if there is a special need for it can also be pre-placed fiber optic.

In addition to the above, the company has also developed a new product line, which is a new type of fiber optic cable.

In addition, in the family network integrated wiring, should give full consideration to the needs of network use, in the study, bedroom and other scenes to choose the established location to install the network cable information box, in order to facilitate the later network use.

Network Topology Selection

Network topology generally refers to the physical layout composed of transmission media and network devices. For home broadband, that is, from the family internal network connection structure, the general family are to choose the star structure, this structure has a simple control, easy to troubleshoot the characteristics of the family broadband network is very suitable for.

Equipment Selection

The family commonly used network equipment is mainly switches and routers, general wireless router configuration is simple and easy to use, the current wireless router also tends to be intelligent, a key to networking, synchronous configuration, beamforming, multi-frequency and multi-user MIMO technology applications have completely broken the traditional cognition of the people.

Simply put, as long as you are sure that the bandwidth is compatible with your wireless router's ports and wireless transfer rate, you can choose your own wireless router based on your preferences.

OK, the above access to home broadband technology, network networking and other aspects of the introduction, may still be insufficient and one-sided, welcome to leave a message in the comments section and add!

I hope that the author's point of view will help you!

Home broadband home optical fiber connected to the optical cat, the optical cat connected to the home intranet. There are a variety of ways to organize the home intranet: single wireless router networking, multi-wireless router networking, AC + AP networking, mesh router networking, as well as power cat networking, etc., and the realization of the premise of the home intranet is a reasonable deployment of the network cable, the following specific say.

Deployment of network cables

The network cables belong to the pre-embedded project, which is also the key to the subsequent family networking, so it is necessary to do a reasonable planning. Due to the small space of the weak box, it is not recommended to be used as a home network convergence node, and it is recommended to set the home network convergence node in the living room.

Living room wiring : Weak box to the living room to pull at least 2 network cables, one of which is used to connect the IPTV TV or IPTV switch, one of which is used to connect to the main wireless router in the living room.

Room wiring: each bedroom, study to the living room to pull at least two cables, one of which is used to connect the room's wireless router, or other wired devices, the other spare or used to connect the room's IPTV TV.

Selection of network cable

At present, the commonly used network cable is ultra category 5, category 6 network cable, in line with the oxygen-free copper AWG24, AWG23 standards, remember not to use that kind of copper-clad aluminum network cable, short life, not pull-resistant. If the family is newly decorated, it is recommended to use category 6 network cable directly.

Appearance, the outer skin of the Super 5 cable is labeled with the words "CAT.5e", Category 6 cable is labeled with the words "CAT.6", and the fiber core has a "cross-bone", which is the most obvious. "This is the most obvious difference.

Networking

A single router may not be able to achieve whole-house coverage of wireless WiFi signals, we can try to use multi-node networking.

The lowest cost: multi-wireless router networking , the wireless router in the living room as the main router, the other wireless routers configured to use as a wireless AP, through the LAN port to connect to the LAN port of the main router, turn off its DHCP service, set an IP address with the same network segment as the main router.

AC+AP networking: each room to place a wireless AP, through the AC manager to achieve the management of all APs, this networking method, you can realize the wireless roaming function. tp-link, UNBT, H3C and other vendors provide suitable for the home AC+AP networking program.

mesh router networking : If the pre-built network cable is not reasonable or not pre-built network cable, then you can consider mesh router networking, mesh router has multiple nodes composed of three nodes can be connected to each other, the stability of the better, if you use the wireless backhaul, as far as possible, the use of triple-band mesh router.

In short, the family network, the first thing to do is to do a good job of planning, such as where to place the wireless AP, where to place the TV, NAS, etc., reasonable pre-buried network cable, try to use qualified class VI cable. The cable is pre-buried, according to the budget to choose the right way to organize the network.

I'm digital field creator twenty-five, happy to answer your questions

You asked this is three questions, allow me to answer them one by one

The first question, home broadband fiber optic is how to enter the home?

At present, the current basically used PON passive fiber optic network technology for home broadband access, which uses a separate optical fiber to replace the previous cable access, to achieve a good network transmission effect, in the network bandwidth, transmission distance and anti-interference and other aspects of the network can also have a good performance. In the actual performance, it is the operator to the home line dumped into the user's home fiber optic home box location, and then according to the home needs to install broadband.

The second question, how to choose the network cable

At present, the Super 5 cable basically can not meet the demand, if the new choice of cable, it is recommended to directly choose the national standard Class VI cable, and it is best to choose the brand.

The third problem, networking mode selection

Before the more popular networking there are four, respectively, bridge networking, power cat (signal amplifier), mesh networking and ac + ap networking, in the choice of networking mode, you need to consider your actual needs. The first step is to consider the actual use of their own needs, it is recommended to use ac + ap networking, or mesh networking, mesh networking, it is recommended to choose a cost-effective router, such as 360 routers, ASUS, Netgear, TPlink, etc., and need to use their own bandwidth to choose.

Fiber to the home has a very professional term called FTTH (Fiber To The Home), in addition to FTTN, FTTE, FTTR, FTTC, FTTB, FTTZ, FTTO, FTTO, FTTD, FTTP and so on. FTTx is in fact very good to understand, that is, the optical fiber to the realization of a certain place, x is the destination of the fiber optic line.

In the past, in the era of telephone line dial-up Internet access, fiber optic cables to the top of the local telecom office room, the telecom office room to the user's home is connected using telephone lines. After years of conversion, now China's home broadband market has basically converted to fiber-to-the-home, telecom operators and cable operators have generally laid 4 to 12-core fiber-optic cables to the community or commercial buildings room.

The distance from the server room to the user is generally less than 1km, and this distance is generally connected by a single-core fiber optic cable. Ordinary leather cable for the standard figure of eight structure, two sides are parallel to the reinforcement core, the middle of the fiber core.

The current fiber-to-the-home access

The current fiber-to-the-home access includes passive optical network access (PON) and active optical network access (AON). Here you may be difficult to understand the passive fiber optic network and active fiber optic network, passive fiber optic network does not require power to complete the signal processing, like a mirror does not require electricity to reflect the image, while the active fiber optic network is that in the signal transmission process, routers, switches, active optical devices need to be powered by electricity to manage the distribution of user signals. Active fiber optic networks can transmit longer distances, but passive fiber optic networks do not require power costs will be lower, so fiber to the home is still mainly PON passive fiber optic network access.

With passive optical networks, telecom carriers deploy fiber optic line terminals (OLT, Optical Line Terminal) in the central server room, and the passive optical splitter (Splitter) will be as close as possible to the user's optical network unit (ONU, Optical Network Unit).

The distance between the OLT, ONU is the distance from the telecom carrier's central server room to the user's optical network. The distance between the OLT and ONU is the distance from the operator's central equipment room to the user, which is usually several kilometers, while the passive optical splitter Splitter is only a few dozen meters to a few hundred meters away from the ONU. This one-point-to-multipoint relationship streamlines the number and size of equipment in the central room, and also reduces the number of central room wiring.

In the extremely high density of households in the community Splitter if placed directly in the floor of the distribution box, it will lead to maintenance, management is very difficult, want to increase the laying of fiber optic cable has also become very difficult. For example, a 3,000-home neighborhood, would have needed to use nearly 200 cores of fiber optic cable, but generally only 4-12 cores.

So there are OLTs and Splitter placed in the cell room at the same time, while the telecom operator's central server room and the cell room between the only low-core fiber optic cables to meet the needs of the entire community, and can be accessed according to the increase in the number of users to gradually expand capacity.

Of course, you can also use active fiber optic network access, telecom operators can use low-core fiber optic cables from the central server room to the cell room, but the difference is that the cell room uses a point-to-point network. This access method is easier to achieve two-way stable peer-to-peer rate broadband access compared to passive fiber network access.

User networking after fiber to the home

In the past, in addition to computer networking, there is basically no other networking equipment, so many users in order to save money directly using a cable connected to the computer and optical cat, through the computer side of the dial-up Internet.

Now it's different, now every family has a lot of devices that use WiFi to access the Internet, such as TVs, cell phones, pads, smartwatches, and so on, so nowadays it's common for families to have more than one wireless router to provide WiFi Internet access for multiple devices.

Some large homes have a 1~2 wireless router that can't solve the problem of whole-house coverage, and it's hard to achieve unified management of multiple ordinary wireless routers, and there's no way to achieve seamless roaming of WiFi signals, so the AC+AP networking approach is used.

These are my personal opinions and I welcome your criticism.

This question is very high, almost covering how broadband fiber into the home and into the home is how to network, to achieve the current home of the wired + WIFI network environment, which is very popular.

Fiber to the home

Cable selection

Networking

For the popularity of this issue, you get it?

Your attention and comments are my greatest motivation to move forward, thank you very much.

Three questions,

First, how the fiber into the home, fiber into the home in general new building contractors have been dumped into the user's home to the location of the fiber optic home box, old neighborhoods or factories to go to broadband operators outside the line of personnel dump line into the home to look at the site environment can be a dark line can be open line.

Second, the choice of network cable, 100 megabytes can choose the national standard ultra-five oxygen-free copper cable, feel uneasy about the choice of national standard class VI line, the best brand, such as TCL Loglan, or Amp, if greater than 100 megabytes of broadband, it is recommended to choose the national standard class VI line. If it is a fiber-optic home, you want to put the routing and optical cat separately also need to throw a fiber-optic line to the location of the routing, other rooms or locations need to be connected to the network needs to be thrown to the location of the routing line, so that you can, the main network line to choose a good after the selection of the corresponding category V or VI RJ45 crystal head, such as fixed-line and other business but also to throw the telephone line, as long as it is a national standard telephone line, some of the special environments also need to shield the cable or the cable, or a special environment. Special environments also need to shield the network cable or anti-rodent bite, depending on your actual environment to choose.

Third, the way the network, home, if you choose a relatively stable router, such as Huawei Q2 sub-mother router, Asus, Netgear, low-end brands TPlink, Tenda, Mercury, Lei Ke, it is recommended that you choose a good point, pay attention to the standby amount of the router, if it is a unit or enterprise, the need for professional network engineers to configure the construction, the general connection is made by the main router (firewall)-main Switching - sub-switching - AC controller AP device - terminal equipment, to complete, specifically you still do not understand where you can ask me by private letter

If the district, in the construction of the building when the fiber has been deployed to complete the late only need to operators of the installation of the splitter box from the building to the user's home to pull the optical fiber into the can be. In the user's home is basically a network cable.

As broadband speeds are now faster and faster, many are more than 100M transmission rate, so the choice of network cable, it is recommended to choose Category 6 and above the high specifications of the cable. The topology in the main home network is to a certain point of convergence to the surrounding radiation network cable, the vast majority of families are to the weak box as the center point. The network cable is then routed from the weak box to the rest of the space.

Although wireless Internet access is now common, the cable connection is more reliable, more stable, and lower latency. It is recommended to have at least two cables in each space, both for backup and for the potential addition of smart devices in the future.

Through the carrier's olt, the network cable to choose a gigabit, the router is also a gigabit can be used to maximize the speed of the network

Fiber to the home, usually the operator installers will install fiber optic cats.

Fiber optic cats behind the simple program is to connect the router, and then is connected to the network cable to connect the computer.

The high-end solution is to connect the switch behind the fiber optic cat, and then connect multiple routers from the switch to achieve whole-house coverage.

Of course, masters use ac+ap to achieve seamless wifi roaming. Here involves the relevant complex settings, network whites are not connected to use.

Telecom fiber optic access to the optical cat, the optical cat below the Category 6 twisted pair to the router or computer can be
