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.
Hot Melt Adhesive For Shoe
Hot melt adhesive for shoes refers to a general term for a class of hot melt adhesive products used in the field of shoe processing, which is not a single model of hot melt adhesive film products. Due to the diversity of shoe-making materials, there are many types of hot melt adhesives used in the field of shoe materials. To make a simple summary, the common types of tpu hot melt film with low temperature release film, and the types of pa and tpu hot melt omens.
So, what are the characteristics of using hot melt adhesive as a adhesive for shoe materials compared with traditional white glue and yellow glue? The characteristics of hot melt adhesive for shoes compared with traditional shoe adhesive are mainly in the following aspects:
1, more environmentally friendly than traditional adhesives, both for the production of operators, or consumers are more healthy;
2, better air permeability: especially for shoes with high air permeability requirements, the air permeability of hot melt adhesive will be better than traditional adhesives;
3, better bonding strength: from the perspective of the composite effect, the bonding strength of hot melt adhesive is better than that of traditional glue;
4, from the production point of view: hot melt adhesive is easy to continuous operation, can greatly increase the production efficiency of the enterprise.
