With the continuous advancement of global information construction, the use of fiber optical is becoming more and more popular, and the installation of "Fiber To The Home" has also become the first choice for many families to choose broadband networks. Do you know the tips about fiber optical cable installation?

 

 

Confirm the Quality of Fiber Optic Cable Before and After Installation

In order to avoid quality problems after installation and eliminate disputes that may be caused by cable damage, it is necessary to test the cable quality before installation. Pre-installation testing doesn't need to be too complicated or time-consuming. If the cable shows no signs of damage, the test can be performed using a continuity tracer. If all fibers transmit light, it is likely to be a good cable. If there is even a hint of possible damage to the cable, it must be tested or outright rejected. If you find anything abnormal during the installation, a post-installation test is recommended. The abnormal issue may result from excessive pulling of the fiber cable or something other reasons. Any issue may have influence in the quality of the cable, the sooner the problem is detected and remedied, the better it is.

 

 

Avoid Fiber Optic Cable Waste Or Exceeded Pulling

Two aspects, precise measurement and the cable control of pulling or bending, should be taken into consideration with fiber optic cable installation to avoid unnecessary disasters. Before using a fiber optic cable, you should first accurately measure the required length to maintain the minimum loss budget. When installing the fiber optic cable, please be careful of the pulling load/tensile and fiber bending radius. The glass fiber in the cable is fragile, and the most common form of damage is fiber breakage caused by excessive tension. Therefore, the tension must be kept lower than the specified limit during installation. The most important factor in fiber optic cable installation is to keep the cable's minimum bend radius. If you bend the fiber cable tighter than the minimum bend radius, it may result in increased attenuation and broken fibers. If the elements of the cable are not damaged, when the bend is relaxed, the attenuation should return to normal.

 

 

Do Not Exceed the Maximum Vertical Rise

Each vertical fiber optic cable has a maximum vertical rise, representing the maximum vertical distance the cable can be installed without intermediate support points. The maximum vertical rise is a function of the cable's weight and tensile strength. Make sure not to exceed the maximum rise when cabling.

 

 

Do Not Mix Fiber Optics and Use Paired Fiber Optic Equipment Separately

Single-mode fiber and multimode fiber are usually incompatible because of the large gap between the two in fiber core sizes. The multimode fiber has a core size of 62.5μm or 50μm, while the single-mode fiber core is only 9 μm. If you tried to use multimode fiber over a single mode fiber link, the larger core size of the multimode fiber cable would cause big attenuation loss easily. Therefore, you'd better not mix the two types of fibers. Similarly, you should not mix different accessories such as PC, APC, UPC fiber connectors together as well. In addition, you should try your best to avoid using fibers of various core sizes even if they are the same type. For example, mixing 62.5μm and 50μm multimode fibers is not recommended even if they may be compatible with each other.

 

 

A good fiber optic cable installation ensures the highly effective and smooth working of the fiber optic cables. And it can spare you a lot of energy in the future maintenance and repairs, preventing endless frustrations. Therefore, it is worthy of a good installation for fiber optic cables.
