With the development of network, optical fiber is deeply loved by people. Optical fiber communication is widely used as the media of information transmission because of its unique anti-interference, light weight, large capacity and other advantages. Using the existing transmission lines to lay optical cables is the most economical and effective

fiber to the home (FTTP), also known as fiber to the house (FTTH), refers to broadband telecommunications systems. It is based on optical fiber cable and adopts optoelectronics to transmit multiple high-end services such as telephone triple play, broadband Internet and television to families or enterprises. So do you know what are the fiber-optic home entry schemes

what are the structures of optical fiber entering the home?

there are many kinds of structures of optical fiber entering the home, of which there are mainly two kinds: one is the point-to-point topology, which uses an optical fiber from the central office to each user; The other is passive optical network (PON) using point to multipoint topology. The point to multipoint scheme can greatly reduce the number of optical transceivers and fiber consumption, and reduce the rack space required by the central office. It has cost advantages and has become the mainstream at present

what are the optical fiber entry schemes

1. The developer has installed a weak current multimedia box in the user's lobby, etc.

if enough space can be reserved in the weak current multimedia box (at least 2fe+1pots port ONU equipment can be placed), the ONU equipment can be installed in the box. During construction, the incoming leather cable is directly laid from the incoming weak current concealed pipe to the weak current multimedia box. It is suggested that the developer introduce the strong current into the weak current multimedia box, or the developer, the property and the user should inform the decoration company selected by the user in advance to introduce the strong current into the weak current multimedia box. The cable (Class V cable or white leather cable) from ONU can also be informed in advance by the developer or property with the user, and the decoration company selected by the user will uniformly consider indoor wiring

if there is no ONU installation position in the weak current multimedia box, the following suggestions can be made to the developer:

a. the specification provided by Unicom is 450mm× 350mm× For 100mm weak current multimedia box, it is recommended that the developer replace the existing weak current multimedia box, or install a new weak current multimedia box near the strong current power supply in the user's room, or install a new weak current multimedia box at the user's door to meet the installation needs of ONU equipment. It is suggested that the developer introduce strong current and concealed pipes from the user's room to the newly installed weak current multimedia box

b. if the developer does not agree with the above suggestion a, the incoming leather fiber optic cable can be directly threaded to the weak current multimedia box installed by the developer. After the cold connection of the fiber optic cable when the user needs it, it can be threaded to a suitable position in the user's room that can provide power for the ONU equipment, and the ONU equipment is exposed. Unicom can suggest developers or property owners to inform users before decoration. If users have broadband needs, the decoration company selected by users should uniformly consider indoor wiring

2. Weak current multimedia box is not installed in the developer's user room

the specification is 450mm× provided by Unicom; 350mm× For 100mm weak current multimedia box, it is recommended that the developer install the weak current multimedia box, or install the weak current multimedia box at the user's door to meet the installation needs of ONU equipment. The developer will introduce strong current and concealed pipes from the user's room to the newly installed weak current multimedia box. The cable (Class V cable or white leather cable) from ONU can be informed in advance by the developer or property with the user, and the indoor wiring can be considered by the decoration company selected by the user

conclusion: the above introduces the optical fiber home entry scheme, and I hope it will be helpful to you. For more relevant knowledge, please continue to pay attention to the information platform. More wonderful content will be presented for you in the follow-up
