Fibre optic cable BlueOptics CAB-SMF-ST-LC-1 1 m G.657.A1 LC ST

The BlueOptics CAB-SMF-ST-LC-1 1 m G.657.A1 LC ST is a single-mode fibre optic patch cable intended for short runs in network installations and data centers. The cable uses G.657.A1 fibre, providing improved bend performance and low attenuation for high-speed data transmission. The assembly pairs an LC connector on one end with an ST connector on the other, allowing compatibility between devices with differing port types while maintaining single-mode optical performance.

Advantages

This 1 metre BlueOptics cable offers low insertion loss and consistent optical performance thanks to the single-mode G.657.A1 fibre and 125 µm core construction. The mixed-connector configuration (LC to ST) supports flexible connections between equipment with different interface formats. Compact LC termination and robust ST coupling provide stable mating in rack-mounted systems and fibre panels, while the G.657.A1 profile reduces sensitivity to tight bends often encountered in confined routing paths.

Suitable for

• Connecting single-mode transceivers and network equipment with LC and ST ports
• Short interconnects in server rooms, telecom closets and patch panels
• Environments requiring bend-tolerant single-mode fibre routing

Key specifications

• Fibre type: single-mode G.657.A1
• Cable length: 1 m
• Core/cladding diameter: 125 µm cladding
• Connector A: LC (single-mode)
• Connector B: ST (single-mode)
• Polish type: typically UPC or equivalent for single-mode optical performance

How to use

Ensure both endpoints are powered down or protected from electrostatic discharge before connecting. Align the LC connector with the corresponding LC receptacle and insert until it clicks; insert the ST connector by aligning the bayonet sleeve and twisting to lock. Avoid bending the cable below the manufacturer’s minimum bend radius and keep connectors clean of dust and debris to maintain low insertion loss and optimal signal quality.

Recommendations

Store spare cables coiled without tight loops, use dust caps when connectors are not in use, and inspect or clean connector end faces with proper fibre-cleaning tools before installation to reduce return loss and extend service life.
