Conector de fibra ótica SC fêmea–fêmea DELOCK 85991, azul, pack de 4

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.

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.
