1. Open and strip the optical cable and fix the optical cable into the connection box. When fixing the multi-beam tube-type cable, due to the layering of the fiber, the bundles should be placed in order to avoid twisting. Pass the fiber optic cable into the connection box. When fixing the wire, be sure to press it tightly. There must be no looseness. Otherwise, it may cause the cable to roll the core. Be careful not to injure the tube bundle, take about 1 meter of stripping length, and wipe off the grease with toilet paper.
2. Pass the fiber through the heat shrink tubing. Separate the bundles of tubes and fibers of different colors and pass through the heat shrink tubing. The cable that strips the smear is fragile and uses a heat-shrinkable sleeve to protect the fiber optic connector.
3. Turn on the welding machine power supply and select the appropriate welding method. There are two kinds of power supply for the fusion splicer: DC and AC. It should be properly switched according to the type of supply current. The fusion splicer should be placed in the fusion environment for at least 15 minutes before each use of the fusion splicer. Set the welding parameters, pre-discharge time, time, main discharge time, main discharge time, etc. according to the type of fiber. If there is no special case, the automatic welding program is generally selected. Remove dust and fiber debris from the fusion splicer in time during use and after use.
4. Make the fiber end face. The quality of the fiber end face will directly affect the quality of the connection, so be sure to make a qualified end face before welding.
5, clean the bare fiber to tear the cotton into a flat piece, stick a little alcohol, pinch the fiber that has been stripped, wipe the fiber along the axial direction, the force should be moderate, each time you want to use different parts and layers of cotton, so That is to improve cotton utilization.
6. For the cutting of bare fiber, first clean the cutting knife and adjust the position of the cutting knife. The cutting knife should be placed stably. When cutting, the movement should be natural, stable, not heavy, not light. Avoid bad end faces such as broken fibers, bevels, burrs and cracks.
7. Place the optical fiber and place the optical fiber in the V-shaped groove of the optical fiber fusion splicer. Carefully press the optical fiber pressure plate and the optical fiber clamp. Set the position of the optical fiber in the pressure plate according to the length of the optical fiber cutting. Close the windshield and press the fusion key to complete the operation. Splicing, the estimated loss value is displayed on the fiber fusion splicer display.
8. Remove the fiber and heat it with a fusion machine. Check for gas or water drops, and if so, redo.
9, disc fiber and fixed. The scientific disk method can make the fiber layout reasonable, the additional loss is small, and the time and the harsh environment can be tested to avoid the fiber breakage caused by the backlog. In the case of disc fiber, the larger the radius of the disc fiber, the larger the arc, the smaller the loss of the entire line. Therefore, it is necessary to maintain a certain radius to avoid unnecessary loss when the laser is transmitted in the core. The tenth step is to seal the connection box. The field connection box must be sealed. If the connection box enters the water, the fiber attenuation may increase due to the long-term immersion of the fiber and the fiber fusion point in the water.
Water Treatment
Water treatment is any process that improves the quality of water to make it appropriate for a specific end-use. The end use may be drinking, industrial water supply, irrigation, river flow maintenance, water recreation or many other uses, including being safely returned to the environment. Water treatment removes Pvc Resin contaminants and undesirable components, Shmp Powder or reduces their concentration so that the water becomes fit for its desired end-use. This treatment is crucial to human health and allows humans to benefit from both drinking and irrigation use.
Water is the most crucial compound for life on Earth, Stpp Detergent Grade and having drinkable water is a key worldwide concern for the twenty-first century. All living things require clean, uncontaminated water as a basic requirement. Water covers more than 71 percent of the earth`s surface, but only around 1% of it is drinkable according to Ethylene-Vinyl Acetate international standards due to various contaminations . Waste water discharge from industries, agricultural pollution, Sodium Metahexaphosphate municipal wastewater, environmental and global changes are the main sources of water contamination. Even trace levels of heavy metals, dyes, and microbes are hazardous to human health, aquatic systems, and the environment.
