Triple play cable transfer box Description: An overview of the fiber optic cable transfer box used to implement the access network fiber optic trunk cables and wiring connections, allocation and scheduling, widely used in optical fiber access network lines and CATV network transmission line project. Second, the main features 1. SMC box with international aviation high-strength materials (glass fiber reinforced unsaturated polyester plastic) molded from high temperatures, long life, anti-aging, anti-radiation; surface without any protection, with all-weather protection. 2. Box thick, with good insulation effect, can effectively prevent condensation inside the door 3. Using special seal door seal, waterproof door and three-door pin lock, safe, reliable, good sealing. 4. The use of 12-core welding wire integration module. 5. for FC, SC fiber optic adapter installation. 6. Reliable cable fixing and grounding protection device. 7. suitable for a single and ribbon cable end. 8. effectively accomplish Mobile, China Unicom, telecommunications triple play. Space saving construction and construction strength. 9. nice, clear lines, good corrosion waterproof performance and long life. Three functional requirements: 1. Cable fixing and protection functions should have cable access, fixed and protection devices. The cable entry device and the rack, the cable core into the cable protection from damage. Metal parts of the machine cable insulation, metal-sheathed cable and strengthening the core fixed after connecting high-voltage protection should be reliable grounding device. 2. Cable termination function should have a fiber optic termination device that facilitates core cable and pigtail splicing operation, construction, installation and maintenance. And protect joints can be fixed without displacement straight and avoid external influence to ensure that the core coiled cable, pigtail from damage. 3. Wire transfer function via fiber jumper connector fitting. Scheduling can be quickly and easily in the cable core to change the channel number and the sequence of optical transmission systems. 4. Protection cable pigtail cable core and core after stripping the protective device and after the introduction of fixed fiber termination unit. 5. Capacity and capacity per rack unit capacity (determined by the number of adapters) to be specified in product standards, the fiber termination devices, pigtails plate line equipment, deck adapters, pigtails and adapters at full capacity within the range should be able to complete set configuration.
