On such a hot day, you definitely don’t want to go out. You’re blowing the air-conditioning and surfing the Internet, watching high-definition IPTV, and browsing Moments, but do you know how fiber optic broadband gets to your home?

It is not easy for a thin optical fiber to enter the homes of ordinary people!

Fiber to the home is called FTTH (Fiber To The Home), which refers to the direct connection of optical fiber to the ONU in the user's home from the operator's OLT computer room.

The network between the OLT room and the ONU is called the ODN (Optical Distribution Network) optical distribution network. The optical distribution network is composed of various equipment such as optical junction boxes, optical connector boxes, optical distribution boxes, and optical cables. Provide a transmission channel between.

In ODN, optical cables are the lowest-level infrastructure for optical signal transmission, and are divided into backbone optical cables, distribution optical cables and household optical cables.

Backbone optical cable

Trunk fiber optic cable: it is the feeder fiber optic cable, which refers to the section of fiber optic cable from the end office to the optical transfer box. Generally, a general-purpose outdoor fiber optic cable is used. The number of fiber cores of the backbone fiber optic cable will be relatively large, ranging from hundreds of cores to hundreds of Cores, even thousands of cores.

The laying of backbone optical cables usually includes pipelines, direct burial and overhead methods.

Distribution cable
Distribution optical cable: refers to the section of optical cable from the optical junction box to the optical distribution box. Generally, a general-purpose outdoor optical cable is used.

The construction method of the distribution optical cable refers to the main optical cable. Between buildings in the city, we can often see neat and firm distribution optical cables bundled along existing pipes or external walls.

Home fiber optic cable

Home fiber optic cable: it is a sheathed fiber optic cable, which refers to a single-core or multi-core sheathed fiber optic cable connected to the user's home.

Generally, FTTH home optical cables use butterfly-shaped optical cables, which usually have good bending performance, resistance to lateral pressure, resistance to torsion, simple structure, convenient stripping, and on-site termination of optical fibers. This is also convenient for passing through vertical shafts in indoor environments. Laying of concealed pipes, exposed pipes, trunking or indoor nailing methods, etc., improves user satisfaction with construction.

No matter which section of the optical cable, the communication person must comply with strict acceptance standards during construction to ensure the quality of the project and provide users with higher-quality services.

In ODN, the optical cable is connected to various equipment such as OLT, optical switch box, optical connector box, optical distribution box, etc., after various steps such as fiber splitting, patching, connecting, testing, etc., the optical signal is finally sent to your home.

The optical fiber finally arrived at your home... 

Now, connect the optical modem to your home WiFi router and you can go online.

After long-distance transmission and various equipment forwarding, the optical fiber finally arrives at your home.

Fiber-to-home is not easy, but even more difficult is the group of communicators who build and maintain fiber-optic networks.

As we know above, ODN networks are mainly distributed outdoors. The communicators who construct and maintain ODN networks have to travel in the wild for a long time. Regardless of wind and sun, wind and rain, they must stick to the front line to protect the Internet for thousands of households. .

It is the scorching summer, when you are surfing the Internet while turning on the air conditioner at home, it is this group of people who will hold up a perfect summer for you under the scorching sun.
Therefore, if you are unable to access the Internet, or the Internet speed is slow, please do not worry, do not get angry, and do not complain. They will take care of it for you. They are on their way here and they must be busy. If you urge them, they are also in a hurry. I hope you can understand that they are really working hard.
