1、fttb+lan宽带小区的几种布线设计方法Several routing design methods for fttb+lan broadband cellAbstract: in recent years, the broadband is becoming more and more hot, and many telecom and non telecom operators compete fiercely on the last mile. Broadband networks are developing at an unprecedented speed, and the fo

6、inly Ethernet access, xDSL, HFC three kinds of mainstream technology, the following are introduced using FTTB+LAN to solve the routing scheme based on broadband residential Ethernet technology.According to the actual situation of various residential quarters, residential buildings within the distric
7、t can be broadly divided into the following circumstances:1., the construction situation can be divided into: planning area, in the construction of residential areas, has been built.2., according to the residential structure classification can be divided into: multi-storey buildings, small high-rise
8、 buildings, high-rise buildings.3., according to the district structure classification, can be divided into monomer building and building group.According to the actual situation of residential construction, the network wiring can be divided into two major categories: planning, building, district wir
9、ing and built in District improvement cabling, and the latter is more common.Types of multi-storey small high-riseThe number of layers is 689 to 1215I. solutions for high-rise buildings (small high-rise buildings with available weak shafts)The high-rise building has the weak shaft which can be used,
10、 and has the connected basement, this kind of situation is better to solve.The user (such as transfer box into the family for information socket): if the real estate construction in a pipe can be embedded directly into consideration, if the building has been built by the user adapter box (TP) in the
11、 user at the user application, to be home again. If the weak vertical shaft can obviously use the existing pipe groove to enter the household, it is possible to consider that the transfer box is installed in the weak vertical shaft, and when the user opens, the utility model is passed through the ex
12、isting pipe groove of the weak current well;Horizontal cable: horizontal cable vertical section of the laying, can use the original weak line groove,Indeed due to the actual situation and can not use the original line slot, to consider the installation of special (for broadband network) slot, slot s
13、ize to set according to the actual needs, the level of horizontal section (floor) cable laying, in this case, you can use a small slot, can also be used PVC tube. The installation method uses the PVC pipe to do the user transfer box in the shaft (or the door of the household). The level of cable lay
14、ing, can be placed in a line between sub layer, five kinds of cables all up (or down) a direction to the terminal; can also be placed in a line between sub layer, five kinds of cables all up and down along the two direction to the terminal.Floor sub wiring (floor, chassis): floor sub wiring is the i
15、ntersection of main optical fiber cable and horizontal five type cable. It is the place for installing exchange equipment, maintenance and maintenance in the future. When confirming the number and location of the chassis, the length of the horizontal cable should be considered and the wiring standar
16、ds should be met.The main cable: cable can be used single-mode or multi-mode optical fiber cable; outdoor cable cable selection all go indoor use of the indoor cable, some or all go outside; usually a high-rise building has several sub wiring, the wiring between several sub trunk cable is all from the center room directly placed over, or from the the top floor of the first wiring wiring between the child
