## Long description

Qoltec 54159 mounting kit provides an LC/UPC singlemode fiber optic connector designed for terminating and connecting 0.9 mm singlemode optical fibers. The kit is intended to facilitate a reliable optical connection using LC/UPC interface geometry for network and telecommunication links.
Advantages
The assembly offers compatibility with LC/UPC ports and supports singlemode fiber to ensure low insertion loss and stable signal transmission. Its form factor suits compact installations and standard fiber patch panels. The kit simplifies the process of creating a precise optical joint for 0.9 mm singlemode fibers.
Suitable for
Installing or repairing singlemode fiber links with LC/UPC terminations
FTTx, backbone and telecom connections requiring LC interfaces
Field or workshop termination of 0.9 mm singlemode optical fibers
When it may not be suitable
This mounting kit is not suitable for multimode fibers or for fibers with diameters other than ~0.9 mm. It also does not replace factory-terminated pre-polished connectors when extreme factory-grade optical performance or guaranteed connector endface geometry is required.
Key specifications
Connector type: LC/UPC
Fiber mode: Singlemode
Compatible fiber diameter: approx. 0.9 mm
How to use
Prepare the singlemode fiber by stripping and cleaning the coating and cladding to the required length, then insert the fiber into the connector assembly according to the kit instructions. Secure and polish or terminate the fiber end as specified for LC/UPC connectors, and test the optical connection with appropriate measurement equipment to verify insertion loss and return loss.
What to consider before purchase
Confirm your fiber is singlemode and approximately 0.9 mm in diameter
Ensure your system uses LC/UPC connectors
Consider whether factory-terminated connectors are preferable for your application
Usage recommendations
Use proper fiber preparation tools, dust-free environment and optical test equipment after termination to ensure low loss. Follow safety guidelines for handling optical fibers and disposal of fiber scraps.
