Are ceramic ferrules easy to make
As ceramics contract or shrink during the sintering process which requires extremely high heat, the shaping of the ceramic ferrules to within tolerances of less than one micron is not easy. Ceramic ferrules and sleeves are often used in optical connectors, attenuators, fiber stubs, and other optoelectronics requiring low signal loss. Ceramics are hard, inorganic materials similar to pottery but much more sophisticated. Its manufacturing requirements are very high, and parameters such as dimensional accuracy, roundness, and surface roughness need to meet standards to ensure the performance and reliability of.
