■ Introduction of Optical Fiber Cable for Networks in Rural Areas(Vast Countryside)

FTTH networks are divided into urban FTTH networks and non-urban FTTH networks.

The optical network in rural areas, a non-urban network, also consists of the feeder segment, the distribution segment, and the drop segment.

The central office is connected to the optical distribution point via feeder cables, then to the access point via distribution cables, and finally to the home via drop cables.

Compared to the urban FTTH networks, the construction of networks in rural areas is distinctive in cabling due to the environmental differences.

At first, the villages with large areas are irregularly scattered, and the number of subscribers is small.

Secondly, it is challenging to deploy cable in rural areas, often hilly regions, where cabling in a straight line is impossible.

Furthermore, in the lightning-prone and rainy areas of the hilly regions, resistance to electromagnetic interference is required for optical cables.

Therefore. the following aspects should be taken into consideration in the construction of optical networks in rural areas: 

Low cost: The construction costs of networks should be as low as possible since the return on investment(ROI) in rural areas is low

Interregional differences: Conditions like temperature, humidity, and rodent control differ violently among regions,

which have influences on products and construction Utilization of existing resources: 

Existing resources in rural areas, such as poles, lines, and ducts, should be used as much as possible Simple construction: Construction in rural areas should be 

as simple as possible since the operators and constructors are less skillful.
