Zirconia sleeves are mostly
used in adapters for the main purpose of connecting and aligning
two inserted zirconia ferrules together. There are two kinds
of zirconia sleeves; split sleeves and solid sleeves. Different
sleeves can be manufactured in accordance to your application
needs.
Zirconia sleeves are categorized into two types used for
ferrule outer diameters of φ2.5mm and φ1.25mm. These are used
for connecting and aligning ferrules used with ST, FC, SC,
MU and LC Connectors.
Solid Sleeves (precision
sleeves) are often used for connecting optical modules.
Moreover, the solid sleeve requires a more accurate
inner diameter process than the Split Sleeve.
