  • Publication number: 20240134135
    Abstract: This is a type of pluggable optoelectronic transceiver that operates while immersed in cooling fluid for data transmission. The pluggable optoelectronic transceiver consists of an optical module, fluid separating colloid, and colloid separating cover. The fluid separating colloid serves to keep the cooling fluid separate from the optical module, while the colloid separating cover further ensures separation between the fluid separating colloid and the optical module. This design prevents the cooling fluid and the fluid separating colloid from infiltrating the optical module and affecting its operation.
