[0002] With the rapid development of fiber optic technology, especially the development of PON technology, the usage of fiber optic modems (ONUs) for clients is increasing, while operators have higher and higher cost requirements for ONUs. Currently, many users of fiber optic modems have changed from directly using optical modules to directly making devices on the boards of fiber optic modems to control costs. This is the origin of BOSA On BOARD. The BOSA used in traditional BOB optical devices is generally a pigtail-type connector with fiber coiling inside and an SC flange plate added to facilitate optical path connection at external customers. However, the cost of the pigtail-type is higher than that of the plug-in type during production, and it requires fiber coiling, which is inconvenient to use and prone to inconveniences such as pigtail breakage during use.

When the optical device body 11 is assembled, the bottom of the optical device body 11 can be placed through the through hole 13, and then the outer side of the optical device body 11 is placed on the top of the lower positioning plate 12. When the outer side of the optical device body 11 moves downward, the two clamping blocks 15 will be squeezed to move away from each other.
