Pigtail type laser to fiber coupler 
 Products: 
 Pigtail type laser to fiber coupler is often required when the following is recommended: 
 Permanent laser to fiber coupling or semi-permanent laser to fiber coupling (does not require frequent replacement of fiber). 
 Requires a high coupling efficiency, stable output. System requires a low echo polarization reflection system needs to maintain a high capacity. In pigtail laser to fiber coupler, fiber and focusing lens directly through contact with a permanent adhesive, then this combination of lens fiber + placed in the flange angle adjustable by two screws to locate. Because the fiber and the lens is connected between the permanent, so that the optical fiber coupler or a lens can not be transposed. Pigtail type laser to fiber coupler can be divided into-contact (LPSC-01: inside the fiber end face and the lens in direct contact) and non-contact type (LPSC-03: Fiber and a certain interval between the lens). Contact type coupler echo reflection is typically-25dB. in non-contact type of coupler, the fiber end face is ground to a certain internal point of view to reduce the echo reflection, the company can provide-40dB or-60dB echo reflected from non-contact laser to fiber coupler.
