Description

technical field [0001] The invention belongs to the technical field of optical communication, and more specifically relates to an optical module. Background technique [0002] Some devices in the optical module, such as chips, liquid crystals, etc., need to work within a certain temperature range, otherwise the performance of the optical module will be reduced, and even the device will be burned. Therefore, temperature control is required. On the other hand, some devices in the optical module, such as MEMS (Micro-Electro-Mechanical System, MEMS for short) optical mirror, optical path, etc., are very sensitive to external vibrations and need to be damped. [0003] In order to avoid the impact of external vibration on the optical path, a vibration damping device is usually installed between the optical path base plate and the module box. In order to ensure that the temperature sensitive devices on the optical path base plate work within a certain temperature range, it needs to...
