## Summary description

The BlueOptics SFP3131BU1.5MK is a high-quality 1.5 m fibre optic cable designed for reliable data transmission. It features LC connectors and complies with G.657.A1 standards, ensuring optimal performance. With a core diameter of 125 µm, this cable is ideal for InfiniBand applications, providing excellent signal integrity and durability.

## Long description

The BlueOptics SFP3131BU1.5MK is a 1.5 m single-mode fibre optic patch cable with LC connectors, engineered for stable high-speed data transmission. Compliant with ITU-T G.657.A1 recommendations and built around a 125 µm core diameter, the cable is suitable for environments where tight bending radius and low attenuation are required. Its yellow outer jacket and industry-standard LC terminations make it compatible with a wide range of networking equipment and transceivers used in data centres and telecom racks.
Advantages
This fibre optic cable offers low insertion loss and consistent optical performance across the link. Conformance to G.657.A1 ensures improved bend resilience compared with standard single-mode fibres, reducing signal degradation in confined routing scenarios. The LC connector provides a compact form factor for high-density patching, while the 1.5 m length minimizes excess cable in rack-mounted installations. The 125 µm core specification supports reliable coupling with single-mode transceivers and maintains signal integrity for InfiniBand and other high-bandwidth applications.
Suitable for
 Interconnecting SFP/LC transceivers in switches, routers and fibre channel equipment
 Short patch runs in data centres and server cabinets
 Environments requiring tight bend radius routing and cable management
 InfiniBand links and other low-loss, single-mode optical connections
Key specifications
 Connector type: LC to LC
 Fibre type: single-mode, G.657.A1 compliant
 Core diameter: 125 µm
 Length: 1.5 m
 Outer jacket colour: yellow
 Designed for low insertion loss and improved bend performance
How to use
Handle the cable by the connector bodies and avoid touching the ferrules. Before insertion, inspect and, if necessary, clean the LC connector end faces with appropriate fibre cleaning tools to prevent contamination-related loss. Plug each LC connector firmly into the corresponding LC socket on the transceiver or patch panel until it clicks. Route the cable to avoid sharp bends and secure it with cable management accessories to maintain the recommended bend radius and prevent strain at the terminations.
Usage recommendations
Store the cable coiled without tight loops and avoid repeated sharp bends; use fibre-specific cable ties or Velcro straps. For best performance with InfiniBand or high-speed transceivers, verify connector cleanliness and test insertion loss after installation. Replace or reclean connectors if increased attenuation or intermittent link issues occur.
