1 Application Optical Fiber Enclosure
1.1 Application：Protection of optical cable connectors.
1.2 Structure：Fiber optic splice box consists of four parts: housing, internal components, sealing elements and fiber optic splice protection parts.
1.2.1 Box shell: the shell can be installed on the grounding lead device, for the cable connector box and the cable in the metal components out of the ground, can be installed according to the needs of the valve mouth.
1.2.2 Internal components of box
a)Support Bracket：It is the main body of the internal components and is used to support the internal structure；
b)Fiber placement fusion splicing device：For sequential storage of fiber optic connectors (and their protective parts) and residual fiber, the length of the residual fiber can be placed greater than 1.6 m, and the radius of curvature of the residual fiber tray is greater than 37.5 mm. And there is a space for re-connection to provide easy identification of the fiber number mark and convenient operation, the structure of the device our company generally adopts the lifting type, can also use the rotation type and unfolding type, etc.
c)electrical connection device: used to connect, ground or disconnect the metal components of the fiber optic cable.
1.2 Box sealing element: The sealing element is used for the sealing of the cable connector box itself and between the cable connector box and the cable sheath.
1.3 Fiber optic splice protection parts: fiber optic splice protection using heat-shrinkable protection tubes, protective clips.
2 Performance Optical Fiber Enclosure
2.1 Use environment: Ambient temperature－40℃～+65℃； Atmospheric pressure：70 kPa～106kPa
2.2 Storage temperature: -25℃～+55℃。
2.3 Material: The material used for all parts of our cable connector box is engineering plastic, which has stable physical and chemical properties and is compatible with all kinds of materials and can be compatible with the cable sheath material.
2.4 Appearance: No burrs, bubbles, cracks and hollows, warps and impurities on the surface of the optical cable connector box. All the base color is uniform and continuous.
2.5 Fiber optic splice protection: fiber optic splice can be protected in the splice box, the protected fiber optic splice can be protected from moisture, and does not increase the attenuation of the fiber optic splice before protection, its mechanical properties and environmental performance can meet the requirements specified in IEC 1073-1.
2.6 Optical performance: The remaining optical fibers in the fiber optic splice box are coiled in the fiber placement device, and there is no attenuation change in the fiber splice during the installation and operation of the fiber optic splice box.
2.7 Sealing performance: After the cable connector box is encapsulated according to the specified operation procedures, the inflation pressure inside the cable connector box is 100kPa±5kPa, and then it is immersed in a container of water at room temperature for 15min without bubbles escaping, or 24h with no change in the air pressure gauge.
2.8 Re-encapsulation performance: the fiber optic cable splice box according to the specified operating procedures repeated three times after encapsulation for testing. Inflation pressure inside the fiber optic cable connector box is 100kPa±5kPa, soak in a container of water at room temperature and observe steadily for 15min without bubbles escaping, or observe steadily for 24h with no change in air pressure gauge indication.
2.9 Mechanical performance: After the tests of tensile, flattening, impact, bending, twisting and axial compression, there is no change in the box body and parts of the box, no change in sealing performance, no cracks in the shell and its components, no damage and obvious deformation.
2.10 Environmental performance: After the tests of temperature cycling, continuous high temperature, vibration, water vapor penetration, solar radiation, chemical corrosion, etc., there is no change in the body and parts of the optical cable connector box, no change in sealing performance, no cracks in the shell and its components, no damage and no obvious deformation.
2.11 Electrical Performance
2.11.1 Insulation resistance: the insulation resistance between the metal components in the fiber optic cable connector box and between the metal components and the ground is not less than 2×104MΩ.
2.11.2 Withstand voltage strength: fiber optic cable connector box between the metal components, metal components and the ground in the 15kV DC effect, 1min without breakdown, no flying arc phenomenon.
3. Overview of installation operations：
Open the box with power tools and find all the encapsulation accessories: plastic sealing collar, plastic sealing plug, box sealing strip, sealing tape and box body.
First, choose not to use the fiber optic cable port, wrap 4 full turns of sealing tape around the plastic sealing plug and cut it off, as shown in Figure 1 on the ports towards the bottom of the box.
Step 2: Fiber optic cable stripping and fixing，Put on two suitable size plastic sealing collars at the fiber optic cable connector, wrap with sealing tape to 35MM diameter and put into the fiber optic cable port slot.
Step 3: manually place the box seal and shape according to Figure 1 style (note that the interface location in the middle of the end, and require the same side into the middle of the cable port inside the lay section).
Step 4: According to the positioning holes, box on the box cover and lock the screws with tools (required locking torque of 13N or more) as shown in Figure 2.
2. Overhead installation (installation accessories optional): install 2 sets of overhead special parts on the same side of the connector box fasteners at the appropriate location, lock with M8 304 stainless steel bolts, the other end of the overhead special parts installed on the overhead wire, and fixed with M5 fasteners.
3. Pipe wall mounting (optional installation accessories): take out two M5 nuts from the accessory package and install them on the special pipe mounting holes on the shell and install two sets of mounting brackets on the mounting holes at the double end of the same side of the connector box, lock them with M5 bolts, install the other end of the mounting brackets on the pipe wall and fix them on the pipe wall with M6 stainless steel expansion screws.
