First, the concept of fiber enclosures FTTH optical network client wiring devices, mainly for welding into the side optical transmission terminals, splitting, wiring output function, which can effectively carry out the termination of the cable, protection and management, optical transmission network in the process of necessary equipment. Second, the product features 2.1 products are fire-retardant ABS plastic box polycarbonate material mixed live by making high-temperature plastic molding, plastic in steel name, product shape, smooth lines, strong impact, protection of up to IP55 level. 2,2 This product is a multi-purpose wiring devices, both when using the optical splitter boxes can also be when the optical splitter box to use, convenient and flexible operation. 2.3 uses a unique anti-theft lock design, box opening and closing flexible, good protective properties. 2.4 uses a unique hinge structure, the construction can easily remove the lid, and put on to use in welding wire work. 2.5 using the turn plate structure, can be high-density configuration port and spectroscopic facilities. Third, the use way splitter box using 3.1: spectroscopic mode when not at work, using 24 SC-type connector adapter is used as the input and output ends of the cable into each side of the plug 24 SC optical connectivity boxes complete allocation. 3.2 optical splitter box using the way: When you need to use a cassette optical splitter boxes, the boxes Time Division 1 minute 16 minutes or 1 minute 32 placed in the box at the end of the fiber system fixed disk, you can used as optical splitter box. 3.3 optical splitter box using the way: When you need to use the Blade optical splitter can be inserted chip optical splitter 1 minute 8 1 or 2 replica of the front of the cartridge is inserted in the fixed, both can use as an optical splitter box. 1 or 2 is inserted in front of a replica of the cartridge fixed, can be used as a light splitter box. 3.4 optical splitter box using three methods: When both need to use the cartridge, plug-chip optical splitters, optical splitter cassette can be placed in the lower and the Blade optical splitter placed in the upper use. Fourth, the installation and use 4.1 Installation: Open the box, remove the cover from the accessory bag to the plastic expansion nail three sets of holes in the wall lay the specified location, put bolts from the bottom front of the box with three tighten the screws. 4.2 laying fiber optic cable: a pigtail cable stripping outdoors after about 50mm thermal fusion; b hot hot melt after welding pipe welding placed on a replica of the opposite slot; c steel core outdoor fiber optic cable in the bottom of the box to strengthen the core fixed fixed position, the waterproof lock lock; d will place the child in the middle of pirated adapter adapter card position after pigtail splice outdoor cable, plug the card in the adapter; when e user covered wire cable with fast connector link, pull covered wire fiber optic cable plugs into the black, the covered wire cable penetration box, the box reserved for a certain length covered wire cable tray in the box lug fiber chassis, fitted with quick connectors can be. f hole into the cable with fiber optic cabling is not plug sealed to prevent dust from entering the cartridge body. Fifth, the environmental conditions: 1, the working temperature: -40 ° ~ + 60 ° C; 2, relative humidity: 93% (at + 40 ° C); 3, atmospheric pressure: 62kpa ~ 101kpa (approximately 0 to 5000 m above sea level) 4, the insertion loss: ≤ 0.35dB; 5, Callback loss: ≥ 50dB; 6, plug Durability:> 1000 7 Insulation resistance: ≥1000MΩ / 500v (DC) 8, pressure:> 3000v (DC) / 1min no breakdown, no arc.
