English
TO packaging originally referred to a transistor shaped packaging, which has evolved into a coaxial packaging laser device in the laser tube (LD) packaging industry.
The commonly used LD packages are TO46 and TO56, with tube seat diameters of 4.6mm and 5.6mm for TO46 and TO56 packages, respectively; The limited external dimensions of these two packaging forms determine that they are mainly used for low-power laser packaging due to their heat dissipation capability; Among them, TO56 packaged laser tubes are the most widely used in the optical communication industry.
