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.
