Free indoor and outdoor no jumper core 576 288 144 core-core cable transfer box Product Description This product is a fiber access network node interface device trunk cables, fiber has a direct, jumper, coiled, storage, adjustment and other functions, the box of imported double-sided brushed stainless steel, the whole 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, the card access installation, ensure that the fiber, optical cable bending radius of curvature greater than anywhere 40mm, reliable cable stripping, protection, fixed grounding device, providing direct melt unit, enabling the optical fiber Straight melting operation, straight-through unit, enabling the cable is not cut through, the box can be equipped with the base operating floor, overhead, wall installed in three ways for users to choose. 1, Box mining has made of high-strength stainless steel and SMC composite materials, high-strength, anti-aging, corrosion-resistant, all-weather protection and can withstand accidental damage or malignant, the surface electrostatic spray, with strong anti-corrosion performance. Protection class work P65 2, housing all rounded corners all use special mold forming, surface treatment using drawing or electrostatic spray, beautiful appearance. 3, the box with double-layer structure, the middle is filled with high-performance insulation material with good insulation effect, can effectively prevent condensation inside. 4, box door with special seal door seal, waterproof door and three-door locking pins, safety and reliability, a good seal. 5, using 12 core welding wires integrated module. 6, install FC, SC, ST adapters for the three fiber. 7, a reliable cable fixing and grounding protection devices. 8, suitable for single and ribbon cable into the side. 9, product specifications, 144 core, 288 core, 576 core conditions: Operating temperature: -40 ℃ ∽ + 60 ℃ Relative humidity: ≤95% (+ 40 ℃ when) Atmospheric pressure: 70∽106Kpa Storage temperature: -40 ℃ ∽ + 60 ℃ moisture and rain and dust security in line with YD / T988-1998 standard main technical parameters: Insertion Loss: 1.31,1.55um LD light source. ≤0.30dB ≤0.18dB multimode singlemode return loss: 1.31,1.55um LD light source. Singlemode PC≥45dB UPC≥50dB APC≥60dB Insulation resistance: ≥2 × 104MΩ / 500VDC Withstand voltage: 3KVDC / 1min no breakdown, no arc box each surface perpendicular to the surface can withstand the pressure of greater than 980N, the door is open After the vertical pressure outermost end should be able to withstand greater than 200N functional requirements: 1. Cable fixing and protection should have cable access, fixed and protection devices. This means the introduction of the cable and fixed to the frame, to protect the cable into the cable core from damage. Metal part of the cable insulation and machine, cable metal sheaths and strengthen core fixed after the high-voltage protection should be reliable grounding connection. 2. Cable termination function should have fiber optic termination device which facilitates the cable core and pigtail splicing operation, construction, installation and maintenance. And protection of joints can be fixed without displacement straight and avoid external influence to ensure that the core coiled cable, pigtail from damage. 3. Transfer function via fiber optic line jumper connector fitting. Scheduling can be quickly and easily in the cable core sequence number and rerouting optical transmission system. 4. Protection cable pigtail cable core and core after stripping the protective device and after the introduction of fiber optic fixed termination devices. 5. Capacity and capacity per rack unit volume (determined by the number of adapters) shall be defined in product standards, the optical fiber terminating device, pigtail plate line device, the adapter card connector, pigtails and adapters, in full capacity range should be able to complete set configuration.
