Fibre optic cable DELOCK 80158 OS2 25 m, 2x LC to 2x LC, 9 µm, full duplex, yellow/blue

DELOCK 80158 is a 25 m single-mode fibre optic cable with 2x LC connectors at both ends and a 9 µm core diameter designed for full-duplex optical links. The OS2 cable supports long-distance transmission and high-speed data connections between network equipment such as switches, servers, media converters and InfiniBand or fibre-optic interfaces. The cable is available in yellow and blue jacket colours and features a compact diameter and LSZH jacket for installations where low smoke and halogen-free materials are required.

Advantages

The construction uses 9/125 µm single-mode fibre optimized for OS2 performance, delivering low insertion loss and high return loss for stable signal quality over longer distances. LC duplex connectors with ceramic ferrules provide reliable mating and dust protection. The cable's small bending radius and approx. 2.0 mm diameter make it suitable for dense rack and conduit routing while the LS0H/LSZH jacket reduces smoke and toxic gas emission in case of fire. Operating temperature range and full-duplex capability allow use in standard data centre and telecom environments.

Suitable for

• Interconnection of switches, routers and media converters in data centres
• Server-to-server and server-to-switch links in rack environments
• Long-distance patching and backbone single-mode links
• Connections to InfiniBand or fibre-optic network interfaces

How to use

Inspect connector end-faces for dust or debris before insertion and use dust caps when connectors are not in use. Route the cable following the minimum bending radius to avoid microbending losses and secure it with appropriate cable management to prevent strain on the connectors. Insert the LC connectors into compatible LC ports on network devices until they click into place; ensure duplex orientation matches the transmit/receive pairs of the devices. For removal, depress the latch and pull straight out to avoid damaging the connector.

Recommendations

For optimal performance, keep connector end-faces clean using approved fibre cleaning tools, avoid tight bends below the specified 25 mm radius, and protect the cable from mechanical stress and extreme temperatures. Use this OS2 25 m LC–LC cable for single-mode backbone and interconnect links where low insertion loss and LSZH jacket properties are required.
