First, the characteristics and presentation: fiber optic wiring box for wiring connection cable and optical communication equipment through the wiring inside the adapter, light jumper leads optical signal, optical wiring function. Suitable for the protection of connecting cables and wiring pigtail, also applies to the fiber access network using optical fiber termination point. Connector plug durability life> 1000 times. The radius of curvature of the entire control to ensure the position of the fiber radius of curvature at any greater than 30mm. Were made for each line fiber clearly labeled to avoid confusion during maintenance disassembly might cause. Flame: A requirement in line with GB5169.7 experiments. Second, the electrical performance of the connector attenuation (insertion, swaps, repeat) ≤0.3dB; return loss: APC type ≥60dB, UPC type ≥50dB, PC type ≥40dB; high-voltage protection grounding device: Insulation resistance: ≥1000MΩ / 500V (DC). Withstanding Voltage: ≥3000V (DC) / 1min, no breakdown, no arc. Ground wire cross-sectional area:> 6mm2, ground to ground at the obvious signs. Third, the advantages of various joints termination convenient and flexible installation. There are drawers and fixed other specifications; modular fiber enclosures termination easier and more flexible; support for the management of a variety of fiber optic connectors, such as SC, LC, ST, MT-RJ, etc; in a 1U space for up to 48 cores terminated LC or MT-RJ (24 个 24 dual-port LC or MT-RJ) fiber optic connectors; sealed management; previous operation, quick and easy installation; the height of 1U, two built-in optical fiber coiled ring; concave or flush the hidden mosaic installation. Fourth, the introduction of the scope of application of the cable, fixed and stripping protection, fixed fiber splice connections and protection, pigtail storage, jump fiber storage and management, and the fiber cross-connect capabilities; light can be installed at the same time according to customer requirements splitters, WDM and other value-added module unit. For inter-wiring and equipment terminations, use and management of the cable.

With a fixed cable and fiber optic cable termination protection function, transfer line functions, as well as cable core and pigtails protection. Both individually assembled fiber distribution frame, but also with digital distribution unit, with audio wiring unit housed in a cabinet / rack. Constitute a comprehensive patch. The device is flexible configuration, installation is simple, easy to maintain, easy to manage, is a fiber optic cable network termination point line, or a relay point to realize row fiber optic cable splicing and jump fiber access one of the essential equipment. ODF fiber splicing wiring unit box, also known as ODF wiring box is used to introduce fiber optic, fixed and protection, cable and pigtail splice terminal, the user needs according to the actual number of matching the number of units or flanges. 1. Product Structure: fiber splicing wiring unit box housing consists of three parts, the internal components, optical fiber connector protector components. a shell: shell easy to open, easy to install. b internal components include the following components: c carriage: the internal structure of the body, for supporting internal structure; d fiber disc set: there are sequentially deposited for fiber optic connectors (and guard) and the remaining fiber, can the remaining the radius of curvature of the length of the fiber is not less than 1.6m, the remaining fiber disc release is not less than 32mm. And promising to re-splice fiber space provides easy identification number of tags and easy to operate; e fixtures: cable jacket for fixed, cable reinforcing member is fixed and fixed wiring pigtail. protection f fiber optic connectors using heat shrinkable protective tube. 2. Appearance: fiber splicing wiring unit box shape intact, no glitches, no bubbles, no cracks and voids, no warping, no impurities and other defects. All should be uniform continuous background. By electrostatic spray, the color should be uniform, no scratches and open at the end. 3. Material: fiber splicing wiring unit box, the material used in all plastic parts with anti-corrosion properties of metal components using electrostatic spray, to increase its anti-corrosion; physical materials, chemical stability, and between materials good compatibility. 3.1 shrinkable protective tube and filler materials used in hot-melt temperature of not less than 120 ℃, the thermal softening temperature higher than 90 ℃, operating temperature: -25 ℃ ~ + 40 ℃. 3.2 All materials, non-toxic, non-corrosive to human health and other devices without side effects. 4. Structural features: a used 19 "standard installation interface, suitable for a variety of rack-mounted cabinet b on the metal structure, surface electrostatic spray coating, compact structure, beautiful appearance c fully modular design, the whole front of the operation, flexible installation, construction and maintenance easy d pull-out design, integrated set of welding wire welding wire module is suitable for e f ribbon cable bundles and each tray can be installed cassette 12 FC, FC (dual-core) , SC, and ST adapters, adapter front was 30 ° angle, both to ensure the pull radius of curvature of the fiber, but also to avoid laser eye damage. g module can be removed to operate the device outside, easy h cables and pigtails have more than 2m disk storage space management products: FTTH FTTH Series: Fiber quick connector, splice, PLC optical splitter, fiber optic desktop box, fiber optic panels, fiber flange, covered wire cable, fiber optic corridor boxes, fiber points fiber box, ODF fiber distribution cable terminal box, etc. Series: fiber distribution cabinet, fiber patch panels, cable transfer box, ODF box, fused with the integration module, wispy ribbon pigtails, fiber jumpers, splice tray. , fiber optic adapter, fiber optic attenuator, such as MDF MDF Series: MDF, outdoor cabinets, security arrangements, testing row, the security unit, wiring tools DDF Digital Distribution Frame series: Imitation Siemens Digital Distribution, DDF patch panels and other cabling series: network cabinet, jumper frame, patch panels, cable management, network modules, network panels, patch cords, junction box, STB junction box, card access module.
