Cable transfer box Description: This product is fiber optic trunk cable access network node interface device, optical fiber has a direct, jumper, coiled, storage, regulation and other functions, the box with the international aviation material SMC (glass fiber reinforced unsaturated polyester plastic) molded from high temperatures, full front operation, the module rail design, easy to pull the module to take place suitable for ribbon and non-ribbon cable, adapter and connecting unit was 30 ° which is to ensure a positive curvature jumpers radius, and avoid the laser burns the human eye, snap-in installation, ensure fiber, cable bending radius of curvature greater than anywhere 40mm, reliable cable stripping, protection, fixed grounding device, providing direct melt unit, enabling the fiber Straight melting operation, the use of straight-through unit, enabling the cable is not cut through, the cabinet can be equipped with the base operating floor, overhead, wall installed in three ways for users to choose from. 1, Box with international aviation materials SMC (glass fiber reinforced unsaturated polyester plastic) molded from high temperatures, long life, anti-aging, anti-corrosion, with all-weather protection, and can withstand accidental damage or malignant, the surface electrostatic spray, with strong corrosion resistance. Protection class workers P65 2. Case thick, has good insulation effect, can effectively prevent condensation inside the 3 door using special seal door seal, waterproof door and three-door pin lock, safe and reliable, a good seal. 4, using the 12-core welding wire integration module. 5, you can install FC, SC, ST three kinds of fiber optic adapters. 6, a reliable cable fixing and ground protection device. 7, suitable for single and ribbon cable into the side. 8, product specifications, 96-pin, 144-core, 288 core, 576 core, 1152 core .1440 core conditions: Operating temperature: -40 ℃ ∽ + 60 ℃ Relative humidity: ≤95% (+ 40 ℃ when) Atmospheric pressure : 70∽106Kpa Storage temperature: -40 ℃ ∽ + 60 ℃ moisture and rain and dust theft comply YD / T988-1998 standard main technical parameters: Insertion Loss: 1.31,1.55um LD light source. Singlemode ≤0.18dB multimode ≤0.30dB return loss: 1.31,1.55um LD light source. Singlemode PC≥45dB UPC≥50dB APC≥60dB Insulation resistance: ≥2 × 104MΩ / 500VDC Withstanding Voltage: 3KVDC / 1min without breakdown, no arc box each surface perpendicular to the surface can withstand the pressure of greater than 980N, the door opens After the outermost end of the vertical pressure should be able to withstand greater than 200N 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.
