It utilizes premium branded fibres and high-quality ceramic ferrules to ensure minimal signal loss and exceptional durability, making it a dependable choice for professional networking infrastructure.
Advantages
This patch cable offers superior signal integrity due to its high-quality construction and precision-engineered connectors. The use of a flame-retardant LSZH jacket ensures safety by minimizing smoke emission and eliminating halogen release in the event of a fire, complying with strict international safety standards. Each cable is rigorously tested using interferometer and OTDR technology to guarantee optimal performance, and it includes a measurement protocol to verify its low insertion and high return loss characteristics. The robust design supports up to 1500 mating cycles, providing long-term reliability for critical data center and enterprise applications.
Suitable for
Data center interconnections
Enterprise network backbones
Connecting optical transceivers
Patch panel port management
High-speed telecommunications infrastructure
This cable is not suitable for multimode networking environments, as it is specifically designed for singlemode OS2 applications. It should not be used in environments where the required cable length exceeds 7.5 meters without appropriate signal amplification or extension equipment.
Key specifications
Cable length: 7.5 m
Fibre type: Singlemode OS2 G.657.A1
Connector type: LC to LC
Connector polish: UPC/APC
Jacket material: LSZH (Low Smoke Zero Halogen)
Core diameter: 9 µm

How to use
To install the cable, carefully remove the protective dust caps from the LC connectors. Ensure that both the connector tips and the ports on your networking equipment are clean and free of dust or debris. Insert the LC connector into the corresponding port until you hear a distinct click, indicating a secure connection. When routing the cable, avoid sharp bends or excessive tension to maintain the integrity of the fibre optic core. The yellow jacket allows for easy identification within complex cable management systems, helping to maintain an organized and efficient network setup.
What to consider before purchase
Verify that your networking equipment supports singlemode OS2 fibre connections.
Ensure the LC connector interface is compatible with your existing patch panels or transceivers.
Confirm that the 7.5-meter length is sufficient for your specific routing path.
Check if your local building codes require LSZH-rated cabling for fire safety compliance.
Usage recommendations: For optimal performance, always keep the connector ferrules clean using specialized fibre cleaning tools. Avoid touching the connector tips with your fingers, as oils and dust can significantly degrade signal quality. Store the cable in a cool, dry place when not in use and avoid exposing it to direct sunlight or extreme temperatures.
