Fibre optic cable BlueOptics CAB-SMF-SC-SC-3-BO 3 m G.657.A1 SC SC

The BlueOptics CAB-SMF-SC-SC-3-BO is a 3 m single-mode fibre optic patch cable designed for high-speed data transmission. It uses G.657.A1 bend-insensitive single-mode fibre with a 125 µm core diameter and SC connectors on both ends, supporting full duplex communication. The cable is intended for connecting patch panel ports, optical transceivers, and other single-mode fibre links in data centres and network installations.

Advantages

This SC–SC single-mode cable offers low attenuation and high return loss characteristics typical of G.657.A1 fibres, enabling stable signal quality over short and medium link distances. The use of SC connectors on both ends ensures secure, standardized mating with equipment that accepts SC interfaces. The 3 m length provides a practical balance between reach and cable management in patching closets and rack environments.

Suitable for

• Patch panel to patch panel connections in data centres
• Connecting optical transceivers to patch panels or switches
• Short- to mid-range single-mode fibre links in telecom and enterprise networks
• Environments requiring bend-insensitive G.657.A1 fibre for routed or confined cable paths

Key specifications

• Length: 3 m
• Fibre type: Single-mode G.657.A1 (bend-insensitive)
• Core/cladding diameter: 125 µm
• Connector type: SC to SC (both ends)
• Transmission mode: Full duplex
• Sheath type: Low-smoke, zero-halogen (LSZH) where applicable

How to use

Inspect connector endfaces for dust or contamination before installation and clean with appropriate fibre optic cleaning tools if necessary. Insert each SC connector into the corresponding SC port until a positive latch is felt. Ensure proper routing and strain relief to avoid tight bends; G.657.A1 fibre is bend-insensitive but still requires reasonable bend radii for optimal performance. For testing, verify input loss and return loss using optical power meters or OTDR as part of commissioning procedures.

Recommendations

Store and deploy the cable avoiding sharp bends and mechanical stress. Use dust caps on connectors when not in use. Clean connector endfaces before mating and follow standard fibre handling practices to maintain low insertion loss and high return loss characteristics.
