EFB Elektronik O2519.2 Fibre Optic Patch Cable, LC to LC, 2m, OS2 G.657.A2, Yellow

The EFB Elektronik O2519.2 is a high-performance 2-meter fibre optic patch cable designed for reliable single-mode data transmission. Featuring precision LC to LC connectors with APC polish, this cable is engineered to meet rigorous industry standards for structured cabling. The use of G.657.A2 fibre ensures excellent bend resistance, while the 9 µm core diameter supports high-speed network protocols. Encased in a durable, yellow LSZH jacket, this cable provides both physical protection and safety in environments where low smoke and halogen-free materials are required.

Advantages

This patch cable offers superior signal integrity thanks to its high-quality Grade B/2 connectors, which are individually tested and supplied with a measurement report to guarantee performance. The inclusion of aramid yarn provides essential tension relief, protecting the internal fibre from mechanical stress during installation. Furthermore, the LSZH jacket is flame-retardant and compliant with international safety standards, making it a secure choice for professional data centers and enterprise network infrastructures.

Suitable for

• High-speed fibre optic network installations
• Data center interconnections
• Telecommunications infrastructure
• Structured cabling systems requiring bend-insensitive fibre

This cable may not be suitable for environments requiring multimode fibre connections, as it is specifically designed for single-mode applications. It is also not intended for outdoor use where exposure to direct sunlight or harsh environmental conditions could degrade the cable jacket over time.

Key specifications

• Length: 2 meters
• Fibre type: Single-mode G.657.A2
• Core diameter: 9 µm
• Connectors: LC to LC (Male)
• Polish type: APC
• Jacket material: LSZH (Low Smoke Zero Halogen)
• Cable type: I-V(ZN) H
• Color: Yellow

To use the cable, carefully remove the protective dust caps from the LC connectors immediately before insertion. Align the connector key with the corresponding port on your transceiver or patch panel and push until it clicks into place. Ensure that the cable is not bent beyond its minimum bend radius to maintain optimal signal transmission. Always clean the connector end-faces with appropriate fibre optic cleaning tools if contamination is suspected.

What to consider before purchase

• Verify that your networking equipment supports LC connectors and single-mode fibre.
• Ensure the 2-meter length is sufficient for your specific cable routing path.
• Confirm that your system requires APC (Angled Physical Contact) polish to ensure compatibility with existing hardware.

Usage recommendations: For best results, avoid sharp bends and excessive pulling force during installation. Regularly inspect the cable for signs of physical damage and keep the connectors clean to prevent signal loss or network instability.
