## Summary description

Hybrid fiber adapter for connecting SC/UPC to ST/UPC duplex singlemode connectors. Manufactured by Molex PN (MPN RB08743), this inline adapter provides a duplex coupling solution for singlemode (SM) fiber links, enabling reliable mechanical alignment between SC and ST ferrules. Suitable for fiber patch panels, enclosures and point-to-point singlemode connections in telecom and data networks.

## Long description

The Hybrid Fiber Adapter SC/UPC to ST/UPC Duplex Singlemode is an inline coupling component designed to join SC/UPC and ST/UPC duplex singlemode connectors. Manufactured by Molex PN, this adapter maintains precise mechanical alignment between ferrules to ensure low insertion loss and stable optical performance in singlemode fiber links. It is intended for use in fiber patch panels, enclosures and direct point-to-point connections within telecom and datacom networks where mixed connector types need to be mated without re-termination.
Advantages
This hybrid adapter provides a compact, duplex coupling solution that preserves signal integrity by aligning SC and ST ferrules with minimal added attenuation. The SC/UPC to ST/UPC interface supports singlemode transmission and helps reduce installation time by enabling direct mating of different connector formats. The inline form factor fits into standard patch panels and enclosures and is suitable for applications requiring reliable, repeatable physical connections.
Suitable for
 Connecting SC/UPC-terminated cables to ST/UPC-terminated cables in singlemode links
 Integration in fiber patch panels and wall or rack-mounted enclosures
 Point-to-point singlemode connections in telecom and enterprise networks
 Temporary or permanent adaptation when mixed connector types are present
Key specifications
 Connector types: duplex SC/UPC to ST/UPC
 Fiber type: singlemode
 Polish: UPC (Ultra Physical Contact)
 Configuration: inline duplex hybrid adapter
 Mounting: suitable for patch panels and small enclosures (inline coupling)
 Alignment: precision sleeve for mechanical ferrule alignment
How to use
Install the hybrid adapter by inserting the SC/UPC and ST/UPC connector ends into their respective ports until they seat securely. Ensure connectors are clean and free of dust or debris prior to mating to minimize insertion loss and protect fiber endfaces. For rack or panel mounting, position the inline adapter in an appropriate coupler location within the patch panel or enclosure and secure according to the panel’s guidance. Verify optical continuity and signal levels after installation using appropriate test equipment.
Usage recommendations
For reliable performance, clean connector endfaces with approved fiber cleaning tools before mating and avoid excessive bending or strain on connected fibers. Use the adapter in singlemode networks only, and check connectors and adapter alignment if you observe increased insertion loss or intermittent signal loss.
