OPLC (optical fiber composite low-voltage cable) realizes power fiber-to-the-home, and utilizes the low-voltage cable line laid to thousands of households to make full use of the "last mile" resource of the power grid. The optical fiber composite low-voltage cable integrates the power grid resources to realize the “co-construction and sharing†of the network infrastructure, and implements the national “three-network integration†strategy, which can solve multiple constructions of multiple lines such as wires, network cables, telephone lines, and cable TV lines, and avoid Repeated construction caused interference with the normal life and repeated investment of the community. OPLC is another fiber optic composite cable after OPGW and OPPC. Integrating optical fiber, transmission copper wire and copper signal line can solve the problems of broadband access, equipment power consumption, emergency signal transmission, etc. Through PON technology, data, voice, video service transmission and meter data transparent transmission can be realized. Realize remote meter reading, notification and payment of electricity based on Internet of Things technology. Customers can make IP phones, surf the Internet, order video programs, watch HDTVs, and establish smart homes that interact with the power grid. OPLC has the characteristics of high reliability data transmission, low price, convenient connection, etc. The advantages are small outer diameter, light weight and small space occupation; The optical cable and the power line are integrated to avoid secondary wiring and reduce engineering costs; the product has good bending and side pressure resistance performance; and solves the communication problem of the power network. Optical fiber composite power cable plays an important role in future home intelligence, office automation, digital substation, and industrial control network data transmission. Advantages of fiber composite low voltage cable OPLC combines the functions of optical fiber communication and power transmission. Compared with single-function transmission cable, it has high reliability data transmission, low price and convenient connection. It has the advantages of small outer diameter, light weight and small space. The optical cable and the power line are integrated to avoid secondary wiring and reduce engineering cost; and have good bending and side pressure resistance; Solve the communication problem of the power network. Optical fiber composite power cable OPLC has an important position in the future of home intelligence, office automation, digital substation, industrial control network data transmission. Specifically, OPLC can summarize the following five advantages: 1. Combine optical fiber and power transmission and distribution cables to avoid secondary wiring, which can effectively reduce construction and network construction costs. Compared with the traditional FTTH, OPLC is used as the smart grid user access solution, which saves a lot of resources such as metal, pipeline and plastic, which can effectively reduce the cost of entering the community and users. It is the most cost-effective "last one." Kilometer" access plan. 2, applicable to a variety of business types, adaptability, scalability, product adaptation. Using OPLC, with the corresponding equipment and devices, to build mainstream XPON (EPON and GPON) technology, can achieve a variety of services on a transmission line, such as IPTV, Internet access, multimedia phones, voice communications, home smart meters And other business. 3, with strong mechanical properties, such as impact resistance and good resistance to pressure measurement, environmental adaptability. When the company develops this product, it fully considers the complexity of the product's use environment. Domestic mainstream OPLC products are tested according to E1, E3 and E4 in GB/T7424 for tensile, flattening and impact tests, which are consistent with and superior to the standard. Claim. 4. Excellent green and safe performance. To take into account OPLC for user access, OPLC product design incorporates halogen-free flame retardant, fire-resistant and other characteristics, using green materials, based on safety considerations, using flame retardant, refractory materials. 5. The optical unit is compatible with the long-term operating temperature of the power cable. Considering that after OPLC is laid, the service life is long and the compatibility of the light unit with the long-term operating temperature of the power cable is a very important issue. According to the method F1 of GB/T7424, the optical performance indexes meet the requirements of YD/T629, and the performance of various electrical appliances meets the requirements of GB/T12706.1, GB/T5023 and JB/8734.
