Fibre optic cable Qoltec 54311, G.652D single-mode, 5 m, FC to SC, yellow

Qoltec 54311 is a 5 m single-mode fibre optic patch cable featuring G.652D fibre, terminated with an FC connector on one end and an SC connector on the other. The cable's yellow jacket identifies it as single-mode and the FC-to-SC termination provides a reliable interface for connecting equipment with different fibre port types. The 5 m length suits rack-to-rack and equipment-to-panel connections in indoor telecommunication and data centre environments requiring standard single-mode links.

Advantages

The G.652D single-mode fibre minimises signal attenuation over typical indoor distances and supports standard single-mode transmission characteristics. The FC connector provides a secure threaded coupling for stable connections, while the SC connector offers a push-pull design for easy insertion and removal. The yellow jacket ensures easy visual identification of single-mode lines and the pre-terminated assembly reduces installation time compared with field termination.

Suitable for

• Telecommunications and service provider indoor links
• Data centre interconnects between patch panels and equipment
• Connecting devices with FC and SC ports in rack environments
• Test setups and short-range optical lab connections

Key specifications

• Fibre type: single-mode G.652D
• Length: 5 m
• Connector A: FC (threaded)
• Connector B: SC (push-pull)
• Jacket colour: yellow
• Intended use: indoor patching and interconnects

How to use

Inspect connectors and dust caps before connecting to avoid contamination. Align the FC connector with the mating receptacle and tighten the threaded coupling until secure, taking care not to overtighten. Insert the SC connector into the corresponding port until it clicks into place. Route the cable to avoid sharp bends and maintain the minimum bend radius recommended for single-mode fibre to prevent increased attenuation or damage.

Usage recommendations

Store the cable with protective caps on the connectors when not in use and handle by the connector bodies rather than the fibre jacket. For best optical performance, clean connectors before mating and avoid repeated flexing near the connector ends. Use this cable for indoor, short-distance single-mode connections where FC-to-SC compatibility is required.
