Instead of using ceramic as the sleeve material for multimode fiber optic adapters, the more common choice is Bronze.This is because multimode fiber optic adapters are mainly used in some low-cost, short-distance transmission and non-harsh environment applications, and bronze has the following advantages over ceramic materials:
Cost: Bronze is cheaper compared to ceramic materials, thus reducing the manufacturing cost of the adapter.
Machinability: Bronze is easier to machine and mold versus ceramic materials, allowing for easier machining, fabrication and assembly.
Durability: Bronze has a high degree of hardness and abrasion resistance, which allows it to better withstand plugging and connecting operations, increasing the service life of the adapter.
Reliability: Bronze is reliable enough for general multimode fiber optic applications without significantly affecting connection quality and performance.
It should be noted that in some special application scenarios, such as high-speed, high-precision and long-distance transmission of single-mode fiber optic systems, ceramic materials may be used to manufacture adapters, because ceramics have a better resistance to high temperatures and stability performance to meet these stringent requirements.
