Fibre optic adapter SC female to SC female, DELOCK 85990, blue, pack of 4

DELOCK 85990 is a pack of four SC female-to-female fibre optic adapters in blue designed for inline coupling and panel mounting. Each adapter allows two SC-terminated multimode or singlemode fibres to be joined with a secure mechanical interface, providing a compact solution for extending links, replacing damaged connectors, or organizing fibres on patchboards and distribution frames. The blue colour helps identify the adapters within cabling infrastructure and is compatible with standard SC connector dimensions.

Advantages

These SC female-to-female adapters offer a reliable physical coupling with low insertion loss when used with compatible SC connectors. The compact design supports space-efficient installation on panels and patchboards, and the standardized SC interface ensures wide interoperability across multimode and singlemode systems. Supplied as a set of four, the pack is practical for small maintenance tasks or staged upgrades without requiring individual purchases.

Suitable for

• Extending fibre links by connecting two SC-terminated cables
• Panel or patchboard installations in network racks
• Temporary or permanent inline coupling during maintenance
• Organizing and identifying fibre connections in data centers and telecom rooms

Key specifications

• Connector type: SC female to SC female
• Quantity: pack of four adapters
• Colour: blue
• Compatibility: SC standard connector dimensions for multimode and singlemode fibres
• Form factor: compact adapter suitable for panel or inline use

How to use

Ensure both fibre ends to be joined are clean and free of dust or debris before coupling. Insert the SC-terminated ferrule of one cable into one side of the adapter and the matching SC-terminated ferrule of the second cable into the opposite side until each connector clicks into place. For panel installations, mount the adapter in the corresponding panel cutout or on the patchboard according to the panel manufacturer’s guidance. When disconnecting, depress the SC connector latch and withdraw straight to avoid stressing the fibres.

Recommendations

Use a fibre cleaning tool or lint-free wipes with approved cleaning solution before connecting to minimize insertion loss. Match connector types (multimode to multimode or singlemode to singlemode) to maintain signal integrity, and store unused adapters or open connectors with protective dust caps when not in service.
