Optical fiber welding type, what are the way how to choose?

Optical fiber welding type, what are the way how to choose? What is the knowledge of the optical fiber optical fiber welding welding method is engaged in the telecommunications or any optical fiber LAN and network engineering technology company is critical. In simple terms, the use of optical fiber welding is to connect the two optical fiber cable. In addition to the optical fiber fusion welding machine and mechanical connection. Optical fiber welding normally with low loss and high return loss as optimization scheme, cable line is a single long fiber or don't have to type fiber combination of circuit, such as a four 12 48 fiber optic cable core cable. Go back to cut and buried them. The above said to the optical fiber fusion with optical fiber fusion welding machine and mechanical joint of the two methods. If you are just start welding fiber, you can analyze the long-term development in this field, you will choose as a technology is most suitable for your standard, the way is more economic and cost-effective? Two broad categories: mechanical connection and welding mechanical connection: mechanical joint just alignment device, keep the two optical fiber end position precision alignment, so that the light from a single fiber transfer to another. ( Loss of typical values 0. 3 dB) Welding: on the welding machine precise zeroed in on the two fiber ends with some type of heat or electric arc them 'fused' or 'welding' together. The connection of loss is very low. ( Loss of typical values 0. 1 dB) Which approach is better? You can choose a more economical way; Mechanical splicing has lower initial investment, how many core spend how many money; Optical fiber welding machine welding way upfront investment is high, but the loss is low, the late can be used. Many telecom and cable companies for their ChangDuanTu network structures are preferred welding for welding machine.
