BOX packaging seals optical chips in a metal enclosure with inert gas, ensuring long-term stability for high-performance transceivers. TO-CAN packaging, originating from the semiconductor industry, provides a compact and cost-effective solution, ideal for small optical modules. Hermetic packaging, or sealing, is primarily used in electronic packaging (in particular in glass-to-metal seals) to protect sensitive components like electrical parts, optoelectronic chips, and semiconductors in vacuum-tight housings. Based on specific transmission distance, chip heat dissipation, cost requirements, channel count, etc. The integrated circuit package shell provides a sealed, stable, and efficient heat dissipation operating environment for the chip through glass-metal and ceramic-metal packaging, protecting the device from humidity, temperature changes, and other physical and chemical environmental conditions.
