## Summary description

QOLTEC 54321 is a 20 m single-mode fibre optic cable using G.652D fibre with SC connector on one end and FC connector on the other. The yellow jacket denotes single-mode fibre; the cable suits network interconnects, patching between equipment with SC and FC ports, and longer-distance optical links in data centres and telecom racks.

## Long description

QOLTEC 54321 is a 20 m single-mode fibre optic cable assembled with G.652D optical fibre and fitted with an SC connector on one end and an FC connector on the other. The cable jacket is yellow to indicate single-mode operation. It is designed for signal transmission between devices with SC and FC ports and for longer-distance optical links in data centres, telecom racks and indoor network installations.
Advantages
The single-mode G.652D fibre minimises attenuation and chromatic dispersion over long distances, delivering stable optical performance for single-wavelength transmissions. Having SC and FC connectors on opposite ends enables direct connection between equipment types without additional adapters. The 20 m length provides flexibility for rack-to-rack or room-to-room links while the yellow outer jacket offers clear visual identification of single-mode cabling in mixed cable environments.
Suitable for
Interconnecting network equipment with SC and FC optical ports
Patch cabling in data centres and server rooms
Telecom rack links and indoor backbone connections
Laboratory and testbench optical measurements requiring fixed-length leads
Key specifications
Fibre type: single-mode, ITU-T G.652D
Length: 20 metres
Connector A: SC (single-mode)
Connector B: FC (single-mode)
Jacket colour: yellow (single-mode identification)
Application environment: indoor, data centre, telecom racks
How to use
Inspect connector endfaces for dust or contamination before use and clean with appropriate optical cleaning tools if necessary. Align the SC and FC connectors with the corresponding ports and insert until a secure mechanical connection is achieved; the FC connector requires a threaded or bayonet-style mating depending on the port. Route the cable to avoid sharp bends and excessive tension, maintaining a bend radius consistent with the fibre specification, and secure it with cable management to prevent stress on connectors.
Usage recommendations
For reliable optical performance, handle the fibre connectors by the boot or housing, avoid touching endfaces, and store unused cables with protective caps fitted. Use this single-mode G.652D cable where low loss and low dispersion are required; for multimode systems select appropriate multimode cables instead.
