Gembird CFO-MDOM4-LC/LC-30M InfiniBand glasvezelkabel LC/UPC 30m OM4

The Gembird CFO-MDOM4-LC/LC-30M InfiniBand fibre optic cable LC/UPC 30m OM4 is a 30-metre duplex multimode fibre assembly intended for high-speed data transmission in networked environments. It uses OM4 multimode fibre with a 50 µm core diameter and LC/UPC connectors on both ends, providing a stable optical link suitable for InfiniBand and other high-bandwidth interconnects in data centres, server rooms and structured cabling installations.

Advantages

This fibre optic cable provides low attenuation and high modal bandwidth associated with OM4 multimode fibre, enabling longer reach and improved performance compared with lower-grade multimode types. The LC/UPC connectors deliver repeatable low-reflection mating and a compact duplex form factor that saves panel space. The 30 m length offers flexibility for mid-range interconnections between racks, patch panels and networking equipment while maintaining full duplex communication for simultaneous bidirectional data flow.

Key specifications

How to use

Inspect both LC/UPC connectors and equipment ports for dust or damage before installation; clean connectors with appropriate fibre cleaning tools if necessary. Route the cable avoiding tight bends and mechanical stress, keeping the bend radius within manufacturer recommendations for multimode fibre. Plug each LC connector into the corresponding duplex ports on the devices or patch panels, ensuring correct polarity for transmit and receive channels. After connection, verify signal integrity and link status using the equipment’s diagnostics or an optical tester.

Recommendations

Store and handle the cable in a dry environment, protect connectors with dust caps when not in use, and avoid routing near strong electromagnetic interference sources. For permanent installations, use cable management and strain relief to prevent excessive pull and bending; perform end-to-end testing after installation to confirm performance meets system requirements.
