Outline of knowledge of fiber optic composite low voltage cables

1. Background: OPLC (optical fiber composite low-voltage cable) to achieve power fiber to the home, the use of low-voltage cable lines laid to thousands of homes, making full use of the power grid "last mile" resources. Fiber-optic composite low-voltage cable integration of grid resources, network infrastructure to achieve "common sharing", the practice of "triple play" strategy, you can solve the power lines, network lines, telephone lines, cable TV lines and other lines of multiple construction, to avoid duplication of construction caused by Interference with the normal life of the community and duplication of investment. 2. structural composition and model specifications: OPLC from the structure can be simply understood as a combination of fiber optic cables and cables. Divided into optical unit part and power transmission unit two parts. Its model specification method also consists of these two components, the insulation core and the sheath of the representation of the same as conventional power cables. In the insulated core and optical unit specifications separated by "+" sign, insulated core specifications, including the number of cores, nominal cross-sectional area.3. Optical unit part of the introduction: the structure of the optical unit can be circular or butterfly or other structures. One of the round optical unit structure mainly has two types of stranded and center tube. The specifications of the optical unit, including the number of optical fiber cores and fiber categories.4. Process and testing requirements of the conductive core part of the same requirements with the power cable, such as 20 ℃ when the conductor DC resistance, insulation thickness, armored steel tape specifications, the thickness of the outer sheath, the finished cable voltage test and other requirements with the same specifications of power cables are the same. Part of the requirements of the optical unit, mainly to assess its transmission performance, optical time domain tester (OTDR) to measure the kilometer attenuation constant of the optical fiber (attenuation constant is a section of optical fiber or cable in the (specified as 1 km) under normal circumstances, the average attenuation, expressed as dB/km).-5, on the BBC Electronic Products Network platform related to the introduction and sales of products brief: BBC Electronic Products Network - a professional agent / production / sales of a variety of {connectors | wiring harness | wire and cable products }; if you have a related [connectors | wiring harness | wire and cable products] purchasing / sourcing needs or would like to buy / to understand which connectors | wiring harness | wire and cable product solutions that we can provide, please contact our Division below!
