## Long description

The EFB Elektronik O2531.3 is a high-performance OS2 single-mode fibre optic patch cable engineered for stable and efficient data transmission in professional networking environments. With a length of 3 meters and a standard 125 µm core diameter, this cable provides a reliable link between passive interfaces and active device ports. The assembly features high-quality SC and LC connectors, ensuring compatibility with a wide range of telecommunications equipment and structured cabling systems.
Advantages
This patch cable utilizes Low Smoke Zero Halogen (LSZH) jacket material, which enhances safety by reducing toxic emissions in the event of fire. Its single-mode OS2 design is optimized for long-distance, high-speed data transmission with minimal signal attenuation. The robust construction ensures durability and consistent performance, making it a dependable choice for maintaining high-integrity connections in demanding IT infrastructures.
Suitable for
High-speed telecommunications networks
Data center interconnections
Structured cabling installations
Connecting active network devices to passive interfaces
This cable is not suitable for multi-mode fiber optic systems, as it is specifically designed for single-mode OS2 applications. It should not be used in environments where the required cable length exceeds 3 meters or where different connector types are required without the use of appropriate adapters.
Key specifications
Fibre type: OS2 single-mode
Length: 3 m
Connector 1: SC
Connector 2: LC
Core diameter: 125 µm
Jacket material: LSZH (Low Smoke Zero Halogen)
Color: Yellow
To use this patch cable, carefully remove the protective dust caps from the SC and LC connectors. Insert the connectors into the corresponding ports on your networking equipment until a secure click is heard. Ensure that the cable is not bent beyond its minimum bend radius to prevent signal loss or physical damage to the fiber core. Keep the connector tips clean and free from dust or debris to maintain optimal transmission quality.
What to consider before purchase
Verify that your networking equipment supports SC and LC interface types.
Ensure that your system requires single-mode OS2 fiber rather than multi-mode.
Confirm that the 3-meter length is sufficient for your specific installation path.
For optimal performance, always inspect the fiber optic connectors for cleanliness before installation and avoid excessive tension or sharp bends during cable routing.
