Fiber optic adapter Extralink SC/UPC Singlemode Duplex, blue, SC/UPC connectors

Extralink SC/UPC Singlemode Duplex fiber optic adapter is designed to join two SC/UPC single-mode connectors in a duplex configuration. Manufactured for fiber patch panels, wall plates and fiber distribution frames, the adapter provides stable mechanical alignment for singlemode fibers and supports bidirectional links. The product is supplied in bulk packs and is finished in blue to indicate singlemode UPC polishing standard.

Advantages

The adapter features high-precision alignment sleeves that ensure low insertion loss and consistent optical performance when connecting SC/UPC singlemode patchcords. Its duplex housing secures two connector positions in a single unit, simplifying installation in panels and plates. The blue color follows industry conventions for singlemode UPC connections, making identification straightforward. The uncoated connector contacts and robust housing provide reliable mechanical stability in typical cabling environments.

Suitable for

• Joining two SC/UPC singlemode patchcords in duplex links
• Installation in fiber patch panels and distribution frames
• Mounting in wall plates and faceplates for fiber outlets
• Indoor fiber backbone and horizontal cabling where singlemode UPC is used

Key specifications

• Connector type: SC/UPC duplex
• Fiber type: Singlemode
• Configuration: Duplex (two channels)
• Color: Blue (UPC identification)
• Quantity: Supplied in bulk packs
• Contact finish: Uncoated connector contacts

How to use

Insert SC/UPC connectors into each of the adapter ports until they click into place, ensuring ferrules are clean and properly aligned. Use one side of the duplex adapter for the transmit fiber and the other for receive to achieve a bidirectional link. For panel or plate installation, secure the adapter housing into the designated cutout according to the patch panel or wall plate instructions. Perform visual inspection and, if available, optical power or loss testing to confirm correct insertion loss and link continuity.

Recommendations

Before making connections, clean fiber endfaces with appropriate fiber cleaning tools to minimize insertion loss and back reflection. Avoid excessive mechanical stress on connected patchcords and maintain proper bend radius for singlemode fiber. Store unused adapters in original packaging to prevent contamination.
