Basic knowledge of optical fiber welding

for wiring and technical personnel, the optical fiber welding machine is an increasingly common skill. The emergence of fiber connection technology, because it is able to make by using the method of stationary or activity type two optical fibers together. For a variety of reasons, people need to in - place the cable Such as: establishing a specific length of the link, or repair the damaged cable or connection. Due to cable factory specifications are usually about 5 km, if need 10 km cable, it is necessary to be together two optical fiber.

fiber welding machine

machinery used in the occasions of need in quickly and easily. Although machinery in place of optical loss level is around 10%, but it can be finished in 5 minutes time in operation. But this loss levels is far better than mechanical connection. Some machinery in place of the connector, according to the advertisement, is removable devices. As a result, the mechanical connection can be used to need activity in place of the occasion.

this connection method through to melt fiber end face and optical fiber connection together. This method through the welding arc discharge will be two optical fibers, need special equipment to operate. Low dissipation caused by welding, but has higher stability. However, the technical requirements for use of expensive welding equipment. When the optical fiber to connect optical fiber core has to be correct. The happening of the loss of fiber connection usually have the following situation: the axis misalignment in the axis of optical fiber displacement will cause the loss. In universal single-mode fiber, the loss of rough calculation formula is: ( Axis misalignment values) 2 * 0. 2. ( For example, if the wavelength of light is 1310 nm, axis misalignment per mu 1 m will cause about 0. 2 dB
