1.62mm LC Ceramic Split Sleeve
UPCERA manufactures precision zirconia ceramic split sleeves with a 1.62mm outer diameter for aligning 1.25mm LC fiber optic ferrules. Designed for optical connectors, adapters, and compact optical assemblies, these sleeves feature a longitudinal slot for controlled ferrule retention and precise alignment. Custom lengths from 2.6mm to 8.0mm are available to meet different assembly requirements.
- Precision Dimensions: Ø1.62 ±0.01mm outer diameter with a nominal inner diameter of Ø1.245mm.
- Customizable Lengths: Available in lengths from 2.6mm to 8.0mm, with a tolerance of ±0.1mm.
- Low Insertion Loss: Designed for optical connections with insertion loss ≤0.2dB under specified test conditions.
- Controlled Retention Force: Slotted structure provides a specified ferrule withdrawal force of 1–3N.
- Durable Zirconia Ceramic: Excellent wear resistance and dimensional stability for repeated ferrule mating.
Product Overview
The 1.62mm LC Ceramic Split Sleeve is a precision alignment component used to position and retain two mating LC ceramic ferrules inside a fiber optic adapter or connector assembly.
Manufactured from zirconia (ZrO₂), the sleeve combines precise dimensional control with a longitudinal split design. This structure allows slight elastic deformation during ferrule insertion, helping maintain alignment and controlled retention.
UPCERA offers a range of sleeve lengths to accommodate different connector designs, compact optical assemblies, and application-specific requirements.

Material and Manufacturing
UPCERA uses precision zirconia ceramic to manufacture alignment sleeves for fiber optic applications.
Zirconia offers high hardness, excellent wear resistance, and dimensional stability, making it suitable for repeated ferrule insertion and withdrawal.
Our ceramic manufacturing capabilities include forming, sintering, precision grinding, and dimensional inspection. Critical dimensions and tolerances are evaluated according to the approved product drawing and application requirements.
Applications
The 1.62mm LC Ceramic Split Sleeve is suitable for applications requiring precise alignment of 1.25mm ceramic ferrules, including:
- LC fiber optic adapters and connectors
- Fiber optic communication equipment
- Optical transceiver and module assemblies
- Fiber optic testing and measurement devices
- Custom optical connection assemblies
Custom Sizes and OEM Solutions
Beyond standard LC configurations, UPCERA supports customized ceramic split sleeves for specific optical assemblies.
For the 1.62mm outer diameter series, lengths between 2.6mm and 8.0mm can be evaluated based on customer requirements.
Customers may submit technical drawings specifying dimensions, tolerances, inspection criteria, and required quantities for engineering review.
For applications requiring different outer diameters, UPCERA also offers other ceramic split sleeve series.
Quality Control
Dimensional accuracy and consistent ferrule retention are important considerations in ceramic alignment sleeve manufacturing.
Depending on the agreed specifications, inspection may include outer diameter, inner diameter, length, slot geometry, visual appearance, and relevant assembly performance tests.
Optical insertion loss and ferrule withdrawal force are evaluated under agreed test conditions using compatible mating components.
