Lower cost solutions will dominate in the intense competition on the basis of meeting performance and reliability requirements.
The traditional optical module applied to an access network and a transmission network adopts air-tight packaging and can be applied to a complex external environment, the working environment of the optical module applied to a data center is relatively good, and the optical module is sealed by glue or only used for simple dust prevention. Hermetic packages mainly use TO packages or parallel sealing processes, while non-hermetic packages mainly use glue seals. Because the airtight packaging process is complex, the cost is very high, if the sealing performance of the glue can be improved, the product sealed by the glue can be applied to the severe application environments of the access network and the transmission network by improving the sealing performance of the glue, the cost of the optical module can be greatly reduced, and the competitiveness of the product is improved.
A common glue sealing structure is formed by connecting a pipe shell with a concave table and a plane cover plate together through glue to form sealing, the contact width of the glue and the pipe shell is narrow, the problem of local sealing tightness caused by sealing defects is easily caused, and meanwhile, due to the limitation of space, the contact width of the glue and the pipe shell cannot be designed to be wide.
Because the traditional sealing mode is not tight in sealing and is easy to cause sealing defects and air leakage, the optical module manufactured by the traditional sealing scheme can only be applied to a data center, has great reliability when being applied to complex application environments such as an access network, a transmission network and the like, cannot bear the environment with high moisture outside, and is greatly limited in application.
In addition, in order to ensure the sealing performance of the traditional cover plate design, the gap between the cover plate and the inner groove on the tube shell is usually designed to be as small as possible, and is usually designed to be smaller than 100um, the cover plate is difficult to align to the inner groove on the tube shell at one time when the cover plate is assembled, and once the glue is not aligned, the glue is unevenly distributed, so that the sealing is influenced.
