XQ7280A-500W is a CO2 laser etcher with CO2 laser as the heat source which is designed independently by OSCOM Technology. The etcher can etch the fiber, which is used to strip the residual pump light and reflected light in the cladding, protecting the optical devices in the optical path effectively. Compared with the cladding optical power stripper made by chemical corrosion, the fiber strength of the cladding optical power stripper made by laser etching is higher, the production process is safer and more environmentally, and there is more space for development.
