The optical fiber distribution frame is an important supporting device in the optical transmission system. It is used for fiber optic cable termination, optical connector adjustment, redundant pigtail storage and cable protection. It has a safe operation and flexible use for optical fiber communication networks. Important role.
The role of the fiber distribution frame
The optical fiber distribution frame serves as the connection of the terminal equipment of the optical cable line and has the following basic functions:
Fusion function
When the optical cable is welded, it is necessary to lead the pigtail welding, and the optical fiber disk can coil the excess pigtail to protect the fusion joint.
Fixed function
After the cable enters the rack, the jacket and the reinforcing core can be connected and fixed.
Provisioning function
The connector attached to the tail cable is inserted into the adapter, and the other connector of the adapter is used for optical path docking. The adapter and the connector can be flexibly inserted and removed for free configuration test.
Distribution of patch panels
The optical fiber distribution frame is mainly divided into 12 optical fiber distribution frames, 24 optical fiber distribution frames, 48 ​​optical fiber distribution frames, 72 optical fiber distribution frames, 96 optical fiber distribution frames, and 144 optical fiber distribution frames.
12-port fiber distribution frame
24-port fiber distribution frame
48-port fiber distribution frame
72-port optical distribution frame
Large capacity optical distribution frame
In summary, the optical fiber distribution frame mainly plays the role of welding, fixing, and deployment in the optical network transmission. The optical fiber distribution frame can be divided into 12 ports, 24 ports, 48 ​​ports, 72 ports, 96 ports, etc. In the weak current project, the number of cores of the fiber fusion needs to be determined first, and then the appropriate fiber distribution frame is selected.
Starch Glue For Paper Tube
The starch glue for paper tube is a starch adhesive made by oxidation of corn starch. It is nontoxic,tasteless, formaldehyde free, easy to operate and convenient to transport.
Product features:
1. High adhesive strength, low adhesive consumption, fast drying, no delamination.
2. Use our glue to make paper tube with good hardness, no brittleness, no bubble, no
crack.
3. The viscosity is stable and has good flexibility, water and moisture resist ance.
4. The ratio of powder and water is 1:2-1:3, and the cost is only 50% of the white emulsion.
Scope of application:
1. Suitable for spiral paper tube mechanical equipment.
2. It can be used for adhesive production of paper barrel, paper corner protector and paper can.
Materials :glue powder,caustic soda,Borax
1.add 25kg water(normal tempreture) into the blender,
2.Then add the glue powder(25kg),and stirring it for 5 minutes to dissolve fully.
3.Take another container,add 10kg of water,will be caustic soda, borax pour into the water,stir well,dissolve fully.
4.The caustic soda and borax solution put into the glue powder solution slowly,stirring evenly,dissolve fully,the
can be used after wait 15 minutes.
Storage considerations:
1.Storage a few days later will be a normal phenomenon of precipitation,you just need stir it again.2.In the process of storage need to cover seal,because the colloid moisture will volatilize,sometimes the glue
powder solution will become solid or Like jelly,at this time ,you can ease with a small amount of water of 0.5-1 kg of caustic soda.
