What are trunk optical cables, distribution optical cables and household optical cables?

In the ODN, optical cable [https://www.dmiscable.com/] is the lowest level of optical signal transmission infrastructure, which is divided into trunk optical cable, distribution optical cable and household optical cable. So what is the trunk optical cable, distribution optical cable and household optical cable? What's the difference between the three? Let's take a look.

First, trunk optical cable

Trunk optical cable: is the feeder optical cable, refers to the section of optical cable between the end office and the optical transfer box, generally choose general outdoor type optical cable, trunk optical cable core number will be more, less than hundreds of cores, more than hundreds of cores, or even thousands of cores.

The laying of backbone optical cable usually includes pipeline, direct buried and overhead methods.

Two, distribution cable

Distribution cable: refers to the cable between the optical handover box and the optical distribution box, and generally uses a general outdoor type cable.

Distribution optical cable construction method refer to trunk optical cable. From building to building in the city, we can often see neat and strong distribution cables tied along existing pipes or outer walls.

Third, household optical cable

Home optical cable [https://www.dmiscable.com/]: that is, leather cable cable, which refers to the single core or multi-core leather cable cable connected to the user's home.

Generally, FTTH household optical cables use butterfly optical cables, which usually have good bending performance, anti-side pressure, anti-distortion, simple structure, convenient stripping, and on-site optical fiber termination function, which is also easy to lay in indoor environment through vertical shafts, hidden pipes, open pipes, cable grooving or indoor napping methods, improving user satisfaction with construction.

No matter which section of optical cable, the communication personnel must comply with strict acceptance standards during construction to ensure the quality of the project and provide users with higher quality services. In the ODN, the optical cable is connected to various devices such as OLT, optical crossover box, optical connector box, and optical distribution box, and after various steps such as fiber splitting, jumper, cutting, and testing, the optical signal is finally sent to the user's home.
