Product Highlights

SC/UPC to ST/UPC Mixed-Connector Configuration

This SKU changes the connector family from SC to ST while keeping UPC polish at both ends. It should be selected when the two endpoints require different connector bodies but the same UPC polish.

Match Each End to the Correct Interface

The cable itself does not define a transmit direction, but each physical connector still needs to match its endpoint: SC/UPC on the SC side and ST/UPC on the ST side.
