## Long description

The Kabelmeister LDM4-LC-300 InfiniBand fibre optic cable 30 m LC/UPC OM4 is a multimode optical patch cable engineered for high-speed, low-latency data transmission. With a 30 metre length and LC/UPC connectors on both ends, this OM4 cable uses a 50 µm core diameter to support full duplex communication and maintain signal integrity over extended runs. Designed for structured cabling in data centres and high-performance computing clusters, the cable provides consistent optical performance for demanding networking applications.
Advantages
The OM4 multimode construction of this Kabelmeister cable offers higher bandwidth and improved modal dispersion control compared with lower-grade multimode fibres, enabling longer transmission distances at higher data rates. LC/UPC connectors provide precise ferrule alignment and low insertion loss, suitable for dense port deployments. A 30 m length balances reach and manageability in rack-to-rack or equipment-to-equipment connections while maintaining full duplex capability for simultaneous bidirectional traffic.
Suitable for
 Data centre uplinks and cross-connects
 High-performance computing (HPC) clusters using InfiniBand
 Server-to-switch and switch-to-switch connections
 Storage area networks (SAN) and backup infrastructure
 Low-latency, high-bandwidth networking environments
Key specifications
 Type: Multimode OM4 fibre optic cable
 Length: 30 m
 Connector type: LC/UPC to LC/UPC
 Core diameter: 50 µm
 Transmission mode: Full duplex
 Typical applications: InfiniBand links, 10/25/40/100+ Gbps multimode networks
How to use
Install the Kabelmeister LDM4-LC-300 by firmly inserting each LC/UPC connector into the corresponding LC ports on networking equipment, ensuring correct orientation and secure latching. Route the cable to avoid tight bends and mechanical stress; respect the manufacturer's minimum bend radius for multimode fibre to prevent signal degradation. For structured cabling, label both ends and secure the cable with appropriate cable management to keep pathways organized and reduce strain. Verify connectivity with optical loss test equipment or the network device diagnostics after installation.
Usage recommendations
Store and handle the cable in a clean environment to avoid contamination of LC/UPC ferrules; use dust caps until final connection. For optimal performance in InfiniBand or high-speed Ethernet setups, use OM4-rated transceivers and maintain proper port cleanliness. Replace the cable if visible damage or persistent signal loss is detected.
