DELOCK InfiniBand/fibre optic cable 75 m OS2 2x LC to 2x LC, 9 µm, Yellow/Blue

DELOCK InfiniBand/fibre optic cable 75 m OS2 2x LC to 2x LC, 9 µm, Yellow/Blue is a single‑mode fibre optic cable designed for long‑distance, high‑speed links in data centres and telecommunication environments. The 75 m length and OS2 single‑mode fibre with a 9 µm core support low attenuation transmission. Both ends feature duplex 2x LC connectors (2x LC to 2x LC) to enable full‑duplex data transfer, while the yellow and blue colour coding helps with quick identification and routing in multi‑cable installations.

Advantages

The cable uses OS2 single‑mode fibre (9/125 µm) compliant with G657.A1 for reduced bend sensitivity and stable transmission across longer distances. Duplex LC connectors with ceramic ferrules and dust protection ensure precision alignment and low insertion loss (< 0.15 dB) together with high return loss (> 55 dB). The jacket is low smoke zero halogen (LSZH), providing reduced smoke emission in case of fire and suitability for indoor installations. A small cable diameter (≈2.0 mm) and a minimum bending radius of 25 mm allow flexible routing in confined spaces.

Suitable for

• Long‑distance single‑mode links in data centres and telecom networks
• High‑speed InfiniBand interconnects and full‑duplex fibre links
• Connecting switches, media converters, transceivers and patch panels
• Indoor installations requiring LSZH jacketing and colour identification

How to use

Inspect LC connector end caps and remove protective dust covers before making connections. Route the cable following the minimum bending radius and avoid tight bends or crushing forces to maintain optical performance. Plug each duplex LC connector into the matching LC adapter or transceiver port, ensuring correct polarity for full‑duplex operation. After installation, test the link with appropriate optical test equipment to verify insertion loss and return loss meet system requirements.

Recommendations

Use this DELOCK single‑mode cable for permanent or semi‑permanent links in rack and cabinet environments where LSZH jacketing and narrow bending capability are required. Maintain connector cleanliness, avoid exceeding the minimum bending radius, and perform optical loss tests after installation to ensure reliable long‑distance transmission.
