Optical Cable Splice Closure Heat Shrinkable Tube's Protection of Optical Fiber

- Mar 26, 2018 -


   The traditional fiber optic cable connection is used by optical fiber fusion splicer convergence which exists great limitations and the construction is also very complicated. Later, it was discovered that the connection loss when using optical cable splice closure heat shrinkable tube to maintain the optical fiber is small. This connection method is also called thermal fusion which the field of optical fiber connection operations are selected this approach over the years;  optical fiber connection, the docking of two optical fiber, is a fixed convergence method.
 
   The disadvantages of the hot melt method are: the equipment is expensive, the demand for electricity is connected, the training of operation demand, the maintenance cost is high, and the operation place is limited. This connection method can still be applied to the field construction section continuously in FTTH construction, but the power and convenience of construction in a narrow indoor environment are greatly reduced.
 
    In the FTTH construction process, fiber optic mechanical connection skills have once been valued by everyone. Optical fiber mechanical connection, as the name implies, there is no need for special instruments. Mechanical crimping and clamping methods are used in the process. According to the principle of V-groove guides, connecting two cut optical fibers together. No electricity is needed, and the manufacturing is small; the optical fiber mechanical connection method also becomes 'cold continuing ', this approach has two key points: 1, the flatness of the optical fiber cutting end; 2, the fiber clamping and fixing reliability.
 
   The final definition of the optical cable is as follows: After a cable arrives at a certain node, all the cores are processed, and the optical cable is no longer extended. Directly-melted fiber is directly welded to another optical fiber cable. Most of the traditional nodes are optical fiber cable connector boxes.
 
   Jumper is the method of selecting fiber optic cable and pigtail welding. After processing, the terminal joints can be flexibly equipped. The traditional nodes are mostly optical cable distribution boxes and optical fiber distribution frames.
 
   Fiber optics are also referred toon as fiber-joint maintenance heat-shrink tubing in the heat shrink tubing professi, consisting of a bright heat-shrinkable tube, a hot-melt tube, and a stainless steel needle (or ceramic rod/quartz rod). The bright outer layer facilitates the detection of proper connection of the optical fiber joints, enables the optical fiber to be assembled simply and safely, shortens the optical transmission characteristics of the optical fiber, and provides strength and protection to the optical fiber joint. The simple operation and reliable function can prevent optical fiber from damaging.


   The use of fiber optic splices for maintenance of heat-shrinkable tubing has the following characteristics:
 
1. The degree of transparency is good, and the fiber bonding situation is clear at a glance;
 
2, Fast shorten and high construction power;
 
3, Soft and high strength;
 
4, The simple use and reliable function;
 
5, The use of temperature: -45 °C ~ 105 °C;
 
6, Environmental protection standards: RoHS.
