Features of OPLC
It features high reliability in data transmission, low cost, and convenient connections. Its advantages include a small outer diameter, lightweight, and minimal space occupation; it integrates optical cables and power lines, avoiding secondary wiring and reducing engineering costs; the product has good bending and side pressure resistance; it solves communication problems in the power grid. Optical fiber composite power cables will play an important role in the future of smart homes, office automation, digital substations, and industrial control networks in data transmission.
Advantages of OPLC
OPLC integrates the functions of optical fiber communication and power transmission. Compared with single-function transmission cables, it OPLC has high reliability in data transmission, low cost, and convenient connections. Its advantages include a small outer diameter, lightweight, and minimal space occupation; it integrates optical cables and power lines, avoiding secondary wiring and reducing engineering costs; it has good bending and side pressure resistance; it solves communication problems in the power grid. Optical fiber composite power cables OPLC will hold an important position in future smart homes, office automation, digital substations, and industrial control networks for data transmission. Specifically, OPLC can be summarized into five advantages:
1. Integrates optical fiber and power distribution cables, avoiding secondary wiring, effectively reducing costs for construction, network installation, etc. Compared to traditional FTTH, using OPLC as the smart grid user access solution saves a significant amount of metals, pipes, plastics, and other resources, effectively reducing costs for access to communities and users, making it the most cost-effective "last mile" access solution currently available.
2. Suitable for multiple types of services, highly adaptable, and with strong scalability, the product has a wide range of applications. By using OPLC along with appropriate devices and components, mainstream XPON (EPON and GPON) technology can be constructed, enabling various services over a single transmission line, such as IPTV, internet access, multimedia telephony, voice communication, and smart home electricity meters.
3. Possesses strong mechanical properties, such as impact resistance and excellent pressure resistance, with strong environmental adaptability. The company fully considered the complexity of the product's operating environment during its development, and domestic mainstream OPLC products underwent tensile, compression, and impact tests according to GB/T7424 standards E1, E3, and E4, all meeting or exceeding the standards' requirements.
4. Eco-friendly and with excellent safety performance. Considering that OPLC is used for user access, the product design incorporates halogen-free flame retardant and fire-resistant characteristics, using environmentally friendly materials, and for safety considerations, flame-retardant and fire-resistant materials are utilized.
5. The optical unit is compatible with the long-term operating temperature of power cables. Considering the long lifespan of OPLC after installation, the compatibility of the optical unit with the long-term operating temperature of power cables is a very important issue. According to the method F1 in GB/T7424, all optical performance indicators meet the requirements of YD/T629, and all electrical performance indicators comply with the requirements of GB/T12706.1, GB/T5023, and JB/8734.
