Nowadays, more and more people live in apartment buildings, dormitories and other multi-dwelling units (MDU), and with the increasing demand for high-bandwidth applications such as high-definition televisions, fiber to the home (FTTH) has become an irreversible trend, UnitekFiber will talk about how to lay a fiber to the home (FTTH) network in a multi-dwelling unit (MDU)?
The factors to be considered when laying fiber-to-the-home (FTTH) network in a multi-dwelling unit (MDU)
Before laying, we should first design a reasonable optical fiber network architecture for the multi-dwelling unit (MDU). The following factors should be considered when designing:
1. How old is a multi-dwelling unit (MDU)?
This factor is very important. If a multi-dwelling unit (MDU) is newly built, its structure is more suitable for modern network access, and it is easier to design a fiber-to-the-home (FTTH) network; if the multi-dwelling unit (MDU) already has in a certain age, its network access infrastructure may be outdated, and some are not even suitable for access to fiber optic networks. Then there will be many restrictions when laying fiber to the home (FTTH) network, and even consume a lot of manpower and material resources.
2. Types of multi-dwelling units (MDU)
The type of multi-dwelling unit (MDU) is another factor that needs to be considered, that is, different types of multi-dwelling units (MDU) are suitable for different fiber to the home (FTTH) structures. In general, there are three types of multi-dwelling units (MDU):
The low-rise multi-dwelling unit (MDU) has 3 floors and a maximum of 12 households. The fiber access point is usually outside the building, which is suitable for each household to use a separate fiber.
The middle-level multi-dwelling unit (MDU) has a maximum of 10 floors, and the number of households is between 12 and 128. The fiber access point is set inside the building, and multiple users can share a fiber interface.
The high-rise multi-dwelling unit (MDU) usually exceeds 10 floors, and the number of households is more than 128. The network architecture of FTTx terminal business is usually distributed vertically, and the network wiring is spread over multiple floors and areas of the high-rise multi-dwelling unit (MDU) to ensure Every household can enjoy an efficient and reliable fiber-to-the-home (FTTH) network.
3. Types of Optical Network Terminal (ONT)
In a fiber to the home (FTTH) network, the type and location of the optical network terminal (ONT) play an important role in the maintenance and operation of the network. There are two types of optical network terminals (ONT): single-dwelling unit optical network terminals (ONT) and multi-dwelling unit optical network terminals (ONT); among them, single-dwelling unit optical network terminals (ONT) can be used in single-dwelling units and It can be used in multi-dwelling units, and multi-dwelling unit optical network terminals (ONT) are only used in multi-dwelling units.
In general, the cost of installing a single-dwelling unit optical network terminal (ONT) will be higher because the related equipment is exclusive to a single household. The multi-dwelling unit optical network terminal (ONT) is that the residents of a unit building share related equipment, but if the number of end users is large, since the end users are connected through copper cables and the optical network terminal (ONT), the number of copper cables required at this time is also Many, the cost will increase. In addition, we should also consider network speed and security. The broadband speed and security provided by single-unit optical network terminals (ONT) will undoubtedly be higher. The following are examples of installing two types of optical network terminals (ONT) in a mid-to-high-rise multi-dwelling unit (MDU):
In this example, a multi-dwelling unit optical network terminal (ONT) is installed in the middle of the building, and multiple users share an optical network terminal (ONT), which has the feature of cost saving.
In this example, a single-dwelling unit optical network terminal (ONT) is installed in the building, and each resident has an exclusive use of an optical fiber, which requires a large number of optical fibers. This method is usually used in newly built multi-dwelling units (MDU).
High-rise multi-dwelling unit (MDU) fiber access solution
Due to the large number of residents in high-rise multi-dwelling units (MDU), a variety of optical fiber hardware equipment such as optical fiber cables, optical fiber distribution frames, and optical cable terminal boxes need to be used when laying fiber-to-the-premises (FTTP) networks. In order to better explain how to lay the optical fiber access network in the high-rise multi-dwelling unit (MDU), the following is an intuitive expression in the form of a legend:
Thanks for your review, we hope it can help you to know the installation of MDU in FTTH solution.We are producing optical fiber indoor/outdoor cables, optical patch panels, fiber cable assembles etc. At the same time, it also produces optical transceiver modules, which can provide With different package types, transmission distance and transmission rate, it also has the characteristics of stable performance and strong compatibility.
