Fibre optic cable EFB Elektronik O2513.7,5 — OS2 single-mode, SC–SC connectors, 9 µm core, 7.5 m, yellow

EFB Elektronik O2513.7,5 is a 7.5 m OS2 single-mode fibre optic cable designed for stable long-distance single-mode transmission. The cable features SC–SC connectors and a 9 µm core diameter, providing low attenuation and reliable signal integrity for full-duplex optical links. It is suitable for high-speed applications such as InfiniBand, data centre interconnects and telecommunication backbones where single-mode performance and controlled dispersion are required.

Advantages

The OS2 single-mode construction and 9 µm core ensure consistent single-mode propagation with minimal modal dispersion. SC–SC connectors provide a push-pull coupling mechanism that is widely compatible with standard optical equipment and patch panels. With a 7.5 m length and yellow outer sheath, the cable offers convenient reach and easy visual identification in structured cabling environments. The full-duplex configuration supports simultaneous bi-directional transmission and is suitable for high-bandwidth links.

Suitable for

• High-speed InfiniBand links and cluster interconnects
• Data centre patching and cross-connects between racks or equipment
• Telecommunication links and long-reach single-mode connections
• Storage area network (SAN) backbones and optical uplinks

Key specifications

• Fibre type: OS2 single-mode
• Core diameter: 9 µm
• Connector type: SC to SC (straight, duplex)
• Length: 7.5 m
• Jacket colour: yellow
• Configuration: full-duplex duplex cable
• Designed for low attenuation and controlled dispersion

How to use

Connect each SC connector to the corresponding SC port on network equipment, transceivers or patch panels, ensuring proper alignment of the ferrules and secure latching. Route the cable along appropriate cable management pathways, avoiding sharp bends and excessive tension to maintain optical performance. For full-duplex links, verify Tx/Rx orientation and confirm link status on the connected devices after installation.

Recommendations

Store and handle the fibre cable following standard optical fibre care: keep connectors capped when not in use, clean endfaces with approved cleaning tools before connection, maintain minimum bend radius specified by the equipment vendor, and avoid twisting or crushing the cable. Use the cable in environments matching single-mode specifications and inspect connectors periodically to ensure low-loss connections.
