Triple play cable transfer box performance Xinze communication cable transfer box is connected to equipment installed outdoors, its most fundamental requirement is the ability to withstand drastic changes in climate and poor working conditions. It should have a waterproof condensation, water and dust, insect and rodent infestation, impact damage and strong features. It must be able to withstand relatively poor external environment. Thus, outside of the case of water, moisture, dust, shock damage, anti-insect pests have requirements are relatively high; its inside temperature and humidity control requirements are very high. By international standards, these projects to the highest standards of IP66. But to achieve this standard tank shell is not much. Currently cable transfer box casing domestic use are: Germany KRONE original box, box unsaturated polyester glass fiber reinforced material (SMC), a better performance in waterproof, moisture-proof, anti-impact damage aspect. Domestic reference KRONE box imitation is the iron-based metal casing (generally reach IP65 standard). For metal box, due to their poor performance in terms of water condensation, doomed to get a lot of use, and gradually be eliminated. Some imitations domestic problems caused due to the material properties of the housing there is a greater difference in the water vapor condenses and impact both the performance and the introduction of German KRONE, in addition since the sealing strip aging poor performance, waterproof, dustproof two the performance in general. Of course, cable transfer box mounted in the outer environment is better, the lower performance requirements, reducing investment would also be acceptable. ① movable optical fiber connector type chosen should meet the relevant standards set forth in the "insertion loss" and "return loss" requirement. ② high-voltage protection grounding voltage level between the metal parts and the cabinet should not be less than DC 3000V, 1min without breakdown flashover. Insulation resistance ③ high-voltage protection grounding metal between the workpiece and the housing, in the test voltage is 500V DC conditions, not less than 2'104MW. ④ high-voltage protection and grounding cable in metal to strengthen the core, ground-sectional moisture barrier and armored attached should not be less than 6mm2. 2 Capacity Xinze communication cable transfer tank capacity is the maximum number of cable transfer box can into the side of the core. The size of the volume capacity of the box, the overall cost, construction maintenance difficulty is proportional, so should not be too large. In the actual design and engineering, people on the capacity issue cable transfer me seems only requires the capacity the better, but the consequences this may bring are: Box volume increases, equipment prices increased. In fact, we often say the transfer box should refer to the capacity of its fiber distribution capacity, or trunk cables with fiber-optic cable with fiber capacity and the capacity of the branch and. Cable transfer box capacity should actually include straight-capacity trunk cables, trunk cables with fiber-optic cable capacity and branch fiber capacity with three parts. 3 Features ● IP65 stainless steel enclosure is made of high strength stainless steel, high strength, anti-aging, corrosion resistance, and can withstand accidental damage or malignant ● all corners of the box using a dedicated whole fillet mold forming, surface treatment using Drawing or electrostatic spray, beautiful appearance ● box with double-layer structure, the middle is filled with high-performance insulation material with good insulation effect, can effectively prevent condensation inside the door ● using special seal door seal, waterproof door three-point door locks and locking pin, safe, reliable, good sealing ● 12-core welding wire integrated module ● equipped with FC, SC fiber optic adapters ● Reliable cable fixing and grounding protection ● suitable for single and ribbon cable into the side SMC ● box with international aviation high strength material SMC (glass fiber reinforced unsaturated polyester plastic) molded from high temperatures, long life, anti-aging, anti-radiation; surface without any protection, with all-weather ● thick protection box, with good insulation effect, can effectively prevent condensation inside the door ● using special seal door seal, waterproof door and three-door pin lock, safe, reliable, good sealing ● 12-core fusion ● integrated module wiring for FC, SC fiber optic adapter installed ● Reliable cable fixing and grounding protection ● suitable for single and ribbon cable into the side ● Applicable standards: YD / T 988-2007 4 indicator connector loss (insert, repeat): ≤0.5db return loss: pc≥40db, UPC≥50dB, APC≥60dB fiber optic adapter plug 1000 times the amount of change ≤0.2dB 5 importance Xinze drive traffic network development, telecommunications Business in the new situation and new opportunities, facing the continuous progress of the construction of 3G networks, FTTH continues to accelerate the pace of construction, building triple play ready, telecom business development development situation is excellent, but for telecommunications companies, benefit is the development of the last word, that is to say, in this new situation, how to win the market, how to have a large number of users, grab the upper hand in the market, this is the most critical. For telecommunications companies, the first to build a solid foundation network, with a wealth of basic resources, that is, how to build a resource-rich, Xinze communications network reliable fiber optic network physical network, it is necessary to think about the telecommunications business problem, and the light transfer me to play a very important role in the construction of the entire local cable network, will help build an extension and continuation of the cable. In order to improve the utilization of fiber optic backbone, reducing the number of open dial cable connector introduced, effectively improve the safety and reliability of fiber optic cable, it recommended the establishment of the necessary cable transfer box in the trunk cable routing in the local cable network construction. Cable transfer box of the user-side cable, the box can be carried out one by one, according to the development needs of users, the transfer tank capacity of 288 core selection can be based. The trunk cable transfer box should be the nearest access to the base station (access layer node). In order to increase the flexibility of access, the cable can be part of the backbone core nodes connected to the aggregation layer. Xinze communications cable in the building there are two modes: bus structure and ring structures. Line structure is from the central office to each use only one cable transfer box large number of fiber optic cable network, which is generally used in business less scope small non-priority areas. Ring structure refers to all commonly used cable transfer me to a big number of fiber optic cable, fiber optic cable end to end in the central office terminal, network self-contained closed-loop, the core distribution with the same bus structure. In short, the optical transfer box application on the local cable network is important for the effective management of the cable core and the use of rational planning, meticulous management to improve cable core, while the construction of a fiber optic network with the flexibility and good scalability let the cable physical network to better serve the development and construction of telecommunication services. 6 assembly requirements ① door opening angle should not be less than 120 °. ② door open and close flexible and reliable. ③ protective ground at the ground should have clear signs. ④ fiber optic cable in the box no matter where laying turn, should ensure that the bending radius not less than 30mm. ⑤ When cable entry port should be set to protect the cable entry, bending radius greater than 20 times the cable diameter. 7.
