Fibre optic connector FC QOLTEC 54455, multimode, 3.0 mm, pack of 200, black/silver

Qoltec 54455 fibre optic connector FC is a multimode FC-type connector designed for joining and switching optical fibers. Supplied in a pack of 200 pieces, these connectors are intended for use with multimode fiber cables featuring a 3.0 mm outer diameter. The FC connector uses a threaded body and a ceramic ferrule to provide a stable, low-attenuation optical connection suitable for telecommunication and data transmission installations.

Advantages

FC connectors feature a screw coupling that produces a precise and secure joint, reducing loss from movement or handling. The ceramic ferrule ensures accurate fiber alignment and low optical attenuation. Supplied in bulk, the pack of 200 pieces supports larger installation projects and reduces the need for frequent reordering.

Suitable for

• Multimode fiber optic cables with approximately 3.0 mm outer diameter
• Telecommunication and data transmission installations requiring stable threaded connections
• Large installation projects or maintenance tasks needing multiple connectors

When it may not be suitable

These connectors are intended for multimode fibers and may not be appropriate for single-mode applications that require different ferrule polishing or connector specifications. They are also sized for cables around 3.0 mm diameter; cables with significantly different diameters will require compatible connector types or adapters.

Key specifications

• Connector type: FC (threaded coupling)
• Fiber mode: Multimode
• Recommended cable outer diameter: ~3.0 mm
• Ferrule material: ceramic (sintered)
• Pack quantity: 200 pieces
• Product colours: black and silver

How to use

Prepare the multimode fiber by stripping and cleaving according to standard fibre preparation procedures. Insert the fiber into the connector body so the fiber end sits correctly in the ceramic ferrule, then secure the fiber according to the connector’s assembly method (crimping or adhesive, depending on the connector variant). Use the threaded coupling to mate two FC connectors, tightening to ensure a stable mechanical and optical connection. After assembly, inspect and, if necessary, clean the fiber end-face to minimise attenuation.

What to consider before purchase

• Confirm that your fiber is multimode and that the cable outer diameter is compatible (around 3.0 mm).
• Ensure your installation requires FC threaded connectors rather than other connector types (e.g., SC, ST, LC).
• Verify you have the required tools and adhesive/crimp fittings for connector assembly and fibre preparation tools (stripper, cleaver, cleaning supplies).

Usage recommendations

For reliable performance, assemble connectors in a clean environment, follow standard multimode fibre termination procedures, and inspect/clean end-faces before final mating. Store unused connectors in their original packaging to prevent contamination.
