Single Model erbium-doped fiber with high doping concentration, absorption as high as 55 dB / m (1530nm), is used for the production of non-polarized laser and optical fiber amplifier, Short fiber length and the high conversion efficiency of the pump makes the fiber for some special applications.
Photosensitive Erbium-doped fiber is an ideal fiber which is used for distributed Bragg feedback and distributed Bragg reflection. This photosensitive fiber can be used to direct writing fiber Bragg grating without loading Hydrogen. The fiber can support a very short fiber length and improve high pump conversion efficiency. At present, we can complete customize.
Medium doping concentration and short fiber length
High conversion efficiency of the pump signal
Can provide a perfect match of the non-Doped Fiber
