Triple play cable transfer box Description: An overview of the fiber optic cable transfer box used to implement access network fiber optic trunk cables and wiring connections, allocation and scheduling, are widely used in fiber access network lines and CATV network transmission line project. Second, the main features 1. Box using high strength SMC international aviation 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. The casing is 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 and reliable, a good seal. 4. The use of 12-core welding wire integration module. 5. suitable for FC, SC fiber optic adapter installation. 6. Reliable cable fixing and ground protection device. 7. suitable for a single and ribbon cable end. 8. Effective done Mobile, China Unicom, telecommunications triple-play. Space saving construction and construction strength. 9. nice, clear lines, good corrosion waterproof performance, long service life. Three functional requirements: 1. Cable fixing and protection functions should have cable access, fixed and protection devices. The device is introduced and fixed to the cable on the frame, the protection of the cable core into the cable from damage. Metal part of the cable insulation and machine, cable metal sheath and strengthen the core fixed after connecting high-voltage protection should be reliable grounding device. 2. Cable termination function should have the fiber optic termination device that facilitates the cable core and pigtail splicing operation, construction, installation and maintenance. Can be fixed and protect joints straight without displacement, to avoid external influence to ensure that the core coiled cable, pigtail from damage. 3. Transfer line functionality through fiber optic 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 fixed after the introduction of fiber optic termination device. 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 dish antenna device, the adapter card connector, pigtails and adapters, in full capacity range should be able to complete set configuration.
