Fibre optic cable BlueOptics CAB-SMF-SC-SC-20 20 m G.657.A1 SC connectors

The BlueOptics CAB-SMF-SC-SC-20 is a 20 m single-mode fibre optic patch cable engineered for reliable high-speed data transmission. Using G.657.A1 bend-insensitive single-mode fibre and SC connectors on both ends, this cable provides stable optical performance for indoor network cabling. Its 125 µm cladding diameter and standard buffered construction make it suitable for professional interconnections in rack environments, patch panels and network equipment.

Advantages

This fibre optic cable offers low insertion loss and controlled return loss thanks to factory-polished SC connectors. The G.657.A1 fibre specification improves bend performance compared with conventional single-mode fibres, reducing signal degradation in tight routing situations. The 20 m length provides flexibility for connections across server racks or between equipment in communications rooms while maintaining consistent optical characteristics.

Suitable for

• Patch connections in data centres and server rooms
• Interconnects between switches, routers and optical transceivers
• Structured cabling in office and telecom environments
• Indoor installations with limited cable routing space

Key specifications

• Fibre type: single-mode G.657.A1 (bend-insensitive)
• Connector type: SC to SC, simplex
• Length: 20 m
• Cladding diameter: 125 µm
• Typical use: indoor patching and equipment interconnects

How to use

Inspect connector endfaces for dust or contamination before installation and clean with appropriate fibre cleaning tools if necessary. Route the cable avoiding sharp bends and maintain bend radii consistent with G.657.A1 recommendations to preserve optical performance. Insert SC connectors into the corresponding adapter or transceiver until a tactile click confirms proper seating. For rack-mounted patching, manage excess length with cable organizers or Velcro ties to prevent strain on connectors.

Recommendations

Store unused cable coiled loosely and protected from mechanical stress. Use dust caps on connectors when not mated. For long-term installations, verify optical loss with a power meter or OTDR after installation to ensure connections meet system requirements.
