Cable TV Fiber To The Home Network Design

With the rapid advancement of Fiber To The Home, the need for high quality video access and Wi Fi indoor networking is growing. This article gives you a detailed overview of the Fiber To The Home Network design approach.

With the rapid development of technology and the increasing demands of users, the home network has become more complex and problematic, and the network design needs to evolve with the needs of the users. The following is a selection of maintenance scenarios to illustrate the various indoor networking methods for broadband interaction, in conjunction with existing maintenance installations.

In the Fiber To The Home Network design, coaxial cables and network cables are lined up in both the living room and the room, and a separate cable is lined up next to the TV in the living room for the installation of a wireless router. The user has an interactive and broadband service and needs to install interactive and broadband.

Network analysis: This scenario is generally in the new community, the number of such users is relatively small at this stage. And our transmission technology is based on DVB + IP way, at this stage, in addition to the need for coaxial cable, interactive and broadband each need a network cable, while to broadband and interactive access points need to be pre-buried 1 coaxial cable and 2 network cables.

It is ideal for this user to have a cable at home, avoiding interactive and broadband to grab the network cable resources. There are several points to note in the Wi Fi coverage:

① The router can be placed in the right place to cover the whole house with only 1 router, instead of buying a router with enhanced power or installing multiple routers.

It is recommended to purchase a dual-band gigabit router, as there were more single-band 2.4 G routers in the early days, so that you can use the 5 G channel and avoid most interference.

③If the house is large, multiple routers can be installed to ensure full wireless coverage.

Maintenance scenario 2: FTTH user with both coaxial cable and network cable in the living room and room, and 1 coaxial cable and 1 network cable for each TV access point. The user has a broadband + interactive service and a set-top box needs to be installed in both the living room and the room.

Analysis of the network: This situation often occurs in new communities, and the difficulty in installing the set-top box is the lack of network cables in the living room. The main solutions are: ① Separate the unused pair from the occupied network cable and provide it to the set-top box for interactive use;

② Use a power cat to transmit the interactive signal using the household power line; ③ Perform IP multiplexing on the coaxial cable, using baseband Eo
C or active Eo C.

( 1) Fiber To The Home Network design using a network cable splitter

The use of a cable splitter (or manual splitting) to divide the one cable from the weak box to the router (next to the TV) into two strands can solve the problem of shortage of cables for the set-top box. The downside is that the split cable cannot support broadband with a bandwidth of more than 100 M, which has a certain impact on broadband performance. However, at this stage, this model is the most economical and common practice.

(2) Fiber To The Home Network design uses a power cat to extend the interactive channel and transmit network signals using power lines. If the set-top box has a WiFi function, it can be connected directly to the power cat without a network cable. There are many types of power cats on the market today, ranging from 100 megabit to gigabit, to meet a wide range of bandwidth requirements. As the bandwidth requirement for interaction is low, and even the most common power cats can reach a bandwidth of 20 M or more, so the power cats are suitable for interaction.

① Power cats must use the same power line environment under the same electricity meter; data transmission will not take place if they are not under the same meter. If the power line is designed with a three-phase power supply, the role of the power cat is severely limited at this time;

②The power cat has high requirements for current, and the connected power supply must be independent, as long as it comes from a separate socket on the wall plug board, and not together with other electrical appliances on the plug board.

Baseband EoC is the solution used by our company in the early stage. Baseband EoC requires 10 M half-duplex configuration for the interactive port, which has a small bandwidth, and will not be used in the later stage as the ONU equipment shortlisted for tender by our provincial company no longer supports this technology.

The disadvantage is that if the set-top box is not an all-in-one unit, an additional EoC cat is required on the set-top box side. This solution is also suitable for old users who have switched from coaxial cable to FTTH, where the user only has coaxial cable in the home but not the network cable and wants to use broadband and interactive functions.

Installation and maintenance scenario 3: FTTH users, the user’s home room living room study are only row 1 network cable, not row coaxial cable. The user has applied for broadband + interactive services and needs to install a set-top box in both the living room and the study.

This situation occurs in new communities, the traditional transmission method has been unable to solve, here our company piloted the use of I-PON technology, all signals are transmitted using network cable, here there is also the problem of insufficient network cable, the solution is mainly: ( 1) the use of network cable splitter; ( 2) the use of AC + AP way.

( 1) Use a splitter cable

( 2) Use AC + AP

This method allows for full Wi Fi coverage, and the AP panel is easy to install and neat, but the material cost is relatively high. This method also supports access to other network broadband in the network, to meet the user’s multiple use of network lag when the diversion, so that the use of broadband smooth.

The scenario of installation and maintenance is very complex, only part of the above list, in fact, subject to the user’s indoor wiring conditions, user needs, line access methods, terminal equipment, cost and other factors, should be a combination of the above scenarios.

When installing, the installation and maintenance staff should use various networking methods flexibly to meet the needs of interactive and broadband services. On the other hand, in the usual installation and maintenance work, business publicity and new cell construction, the new wiring requirements should be vigorously publicised to users through various channels, and users should be given guidance on indoor wiring.
