## Summary description

DELOCK 85990 is a pack of four SC female-to-female fibre optic adapters in blue. Each adapter provides SC connector compatibility for joining two SC-terminated multimode or singlemode cables. Designed for panel or patchboard use, these compact adapters enable secure, low-loss optical connections and simple inline coupling for network maintenance and extension.

## Long description

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.
Usage 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.
