## Summary description

DELOCK 85991 is an SC female-to-female fibre optic connector set supplied in blue. The pack contains four SC couplers designed to join two SC simplex connectors for fibre links. Suitable for use in optical patch panels, fibre extension and repair tasks where passive coupling of SC-terminated fibres is required.

## Long description

DELOCK 85991 is a set of SC female-to-female fibre optic couplers supplied in blue and packaged as a pack of four. Each coupler provides a simple, passive interface to join two SC simplex connectors, enabling extension or repair of existing single-mode or multimode fibre links where SC-terminated connectors are used. The compact, snap-in design is suitable for mounting in optical patch panels, faceplates or chassis that accept SC-style adapters.
Advantages
The SC female-to-female couplers offer reliable physical alignment between mating ferrules to minimize insertion loss and back reflection. Their standardized SC form factor ensures compatibility with common SC simplex connectors and equipment. Supplied in a pack of four and finished in blue for easy identification, the couplers allow quick replacement or scaling of fibre connections without requiring fusion splicing or specialised tools.
Suitable for
Extending optical patch cords with SC simplex connectors
Temporary or permanent repairs of fibre runs using SC-terminated ends
Mounting in optical patch panels, faceplates or chassis with SC adapter slots
Laboratory setups and field installations requiring passive SC coupling
Key specifications
Connector type: SC female-to-female (adapter/coupler)
Quantity: pack of four couplers
Colour: blue
Compatibility: designed for SC simplex connectors
Mounting style: snap-in/adapter form factor for panel or chassis installation
Function: passive optical coupling for fibre links
How to use
Insert an SC simplex connector from one fibre cable into one side of the coupler and insert the mating SC simplex connector from the second fibre cable into the opposite side until the connectors click into place. Ensure both connectors are clean and free from dust or debris before mating to reduce insertion loss and avoid contamination-related performance issues. The coupler can be mounted into a compatible panel or housing by aligning and pressing the adapter into the designated SC slot until it secures.
Usage recommendations
Prior to connecting, clean each connector endface with appropriate fibre cleaning tools and inspect with a fibre microscope when possible. Avoid excessive bending of the fibres near the connection point and verify optical continuity and signal quality after installation. Store unused couplers in a dust-free environment to maintain endface cleanliness.
