Fibre optic cable Telegärtner LC/LC 9/125 3m

The Telegärtner LC/LC 9/125 3m fibre optic cable is a singlemode duplex patch cable designed for reliable high-speed optical connections. With a 9 µm core diameter and a 3 meter length, the cable provides low-loss transmission suitable for point-to-point links and rack-to-rack connections. The LC/LC connectors on both ends are compact and compatible with standard LC duplex ports. The cable’s yellow jacket provides industry-standard colour coding for singlemode links, simplifying installation and cable management in data centers and telecommunication environments.

Advantages

The cable offers low insertion loss and stable optical performance across singlemode wavelengths, enabling consistent data throughput. The LC duplex connectors ensure secure mating and compact port density, while the 3 m length balances reach and reduced excess slack for tidy installations. The standardized 9/125 µm core/cladding geometry ensures compatibility with singlemode transceivers and passive components commonly used in InfiniBand and Ethernet networks.

Suitable for

• Point-to-point connections between switches, transceivers and patch panels
• High-speed InfiniBand links and singlemode Ethernet connections
• Data centre rack-to-rack or equipment-to-equipment cabling
• Telecommunications and network backbone segments requiring singlemode fibre

Key specifications

• Core/cladding: 9/125 µm singlemode fibre
• Connector type: LC to LC duplex
• Length: 3 m
• Polish/type: industry-standard singlemode polish (UPC/PC typical for LC singlemode)
• Jacket colour: yellow (singlemode identification)
• Duplex/full-duplex support: yes
• Typical applications: InfiniBand, singlemode Ethernet, telecommunication backbones

How to use

Inspect connector endfaces before installation and clean if necessary using appropriate fibre cleaning tools to avoid signal loss. Insert the LC connectors into corresponding LC duplex ports until they click into place, ensuring correct polarity for transmit and receive alignment. Route the cable with gentle bends keeping bend radius above the manufacturer’s minimum to prevent microbending losses. For best performance, avoid tight loops and secure the cable with cable management accessories to reduce strain on connectors.

Usage recommendations

Use the cable for singlemode optical links where a 3 m patch length is sufficient. Maintain clean endfaces and follow proper polarity when connecting transceivers or patch panels. Store and route the cable to avoid kinks and sharp bends; replace the cable if connector endfaces are damaged or if optical performance degrades.
