Example Embodiment

[0024] Example 1

[0025] A method of FTTX network planning based on Passive Optical Network (PON), the steps are:

[0026] 1) Determine the user density in the planned area 1: First, according to the land use and function planning of urban construction, divide the long-term development target number of users N in the planned area by the geographical area S of the planned area to obtain the user density ρ in the planned area.

[0027] 2) Determine the optimal economic radius d2 of the optical line terminal (OLT) in the planned area: Under a certain user density and price system of related resources, there are optical line terminals when the optical fiber access network based on the passive optical network (PON) is networked (OLT) The best economic coverage radius, and corresponding to the minimum investment per user, the planning and design of the access network can refer to the best economic radius d of the planned area for network coverage.

[0028] Put the user density ρ in the...

Abstract

The invention discloses a FTTX network planning method based on passive optical network, comprising the following steps: A determining the planning area subscriber density: the subscriber density of the planning area being equal to the subscriber long-term development target of the planning area; B determining the economy radius of the planning area; C dividing the coverage area: obtaining the coverage area by performing the gridding treatment of the prior planning area; D setting the light line terminal node: selecting the gridding center of the light line terminal coverage area as the FTTX network light line terminal node position based on the passive optical network; E determining the economic radius of the optical splitting zone: the radius of the optical splitting zone being equal to the economic radius; F dividing the optical splitting zone: performing the gridding treatment of the prior planning area; G setting the optical splitting point: selecting the gridding center of the optical splitting zone as the FTTX network light line terminal node position based on the passive optical network. The method is easily realized and operated and suitable for planning and building the optical fiber broadband access network of telecom operator, therefore the broadband speed increasing object of the consumer is realized.

Description

technical field [0001] The invention relates to the technical field of telecommunication optical fiber broadband access network planning and design, and more specifically relates to a passive optical network (PON)-based FTTX network planning method, which can be widely used in the planning and construction of telecom operators' optical fiber broadband access networks. Background technique [0002] With the deepening of mobile communication's role in substituting fixed-line narrowband voice, broadband services have gradually become the profit growth point and strategic investment focus of fixed-line operators. In 2007, the number of broadband access users in my country exceeded 50 million, and it is still growing rapidly. Emerging services such as IP TV, video on demand, online games, and multimedia interaction are testing the existing bandwidth, and the copper-based ADSL access method encounters a development bottleneck. Many domestic operators have started the large-scale ...
