Armored fiber optic jumper can be laid directly in the computer room and various harsh environments without the need for protective sleeves, saving space, reducing construction costs, and greatly improving the convenience of network maintenance. The biggest difference between this product and the traditional optical fiber jumper is that it is designed to produce a small flexible stainless steel ferrule to protect the optical fiber, which is easy to break and be damaged. To achieve functions such as moisture and fire prevention. At the same time, we have developed a special manufacturing process and a unique structure to ensure that the casing and the joint are firmly connected. This unique design makes the construction and wiring of armored fiber optic jumpers simple and convenient, reduces losses during construction, and improves the service life of fiber optic jumpers and improves the safety and stability of the entire system.
