Transmission Distance and Rate Requirements: Determine the required transmission distance and data rate based on the actual application scenario. For long-distance, high-speed transmission needs, such as inter-city communication trunk lines, single-mode fiber optic cables should be selected. For short-distance, lower-speed applications, such as surveillance networks within residential communities, multi-mode fiber optic cables may be more suitable.
Environmental Factors: Consider specific environmental conditions at the installation site, including temperature, humidity, soil composition, and presence of strong electromagnetic interference. In cold regions, select fiber optic cables with excellent low-temperature resistance. In environments with strong electromagnetic interference, choose cables with strong electromagnetic interference resistance.
Mechanical Performance Requirements: Select fiber optic cables with appropriate mechanical properties based on the installation method and potential external forces. Direct-buried cables require strong resistance to compression, tension, and rodent damage; aerial cables must withstand forces like wind and gravity; conduit cables need compatibility with the conduit and sufficient flexibility for bending during installation.
Fiber Core Count: Determine the fiber core count based on actual requirements. If multiple signals need to be transmitted simultaneously or space is required for future expansion, select fiber optic cables with a higher core count. Common outdoor fiber optic cable core counts include 4-core, 6-core, 8-core, 12-core, 24-core, and other specifications.
