## Long description

The BlueOptics SFP3131GU2.5MK InfiniBand fibre optic cable 2.5 m LC Green is a 2.5 metre duplex patch cable engineered for high-speed data transmission in networking and data centre environments. It uses OM5 multimode fibre with a 50 µm core diameter and LC connectors on both ends to provide low-loss, high-bandwidth links suitable for modern InfiniBand interconnects and short-reach optical links.
Advantages
This OM5 LC–LC fibre cable offers improved modal bandwidth for wavelength-division applications and supports high data rates with reduced modal dispersion compared with older multimode grades. The 2.5 m length provides flexible routing in rack and cabinet deployments while minimising excess looped cable. The LC connectors ensure reliable mating with typical transceivers and patch panels used in InfiniBand and enterprise networking hardware. The green jacket makes cable identification straightforward in mixed-fibre installations.
Suitable for
InfiniBand links between switches, host channel adapters and storage nodes
Short-reach connections in data centres and server racks
High-density patch panels and transceiver patching
Applications requiring OM5 multimode performance for multimode wavelength division
Key specifications
Fibre type: OM5 multimode
Core diameter: 50 µm
Connector type: LC on both ends (duplex)
Length: 2.5 metres
Jacket colour: green
Polarity: duplex duplex A-B standard patching
How to use
Install the cable by aligning LC connectors with the transceiver or patch panel ports and pressing until the latch clicks. Route the cable through cable management channels or horizontal trays to avoid sharp bends; maintain the minimum bend radius recommended by equipment vendors. Ensure connectors are free of dust before mating by using appropriate cleaning tools or wipes designed for fibre optics. When disconnecting, depress the LC latch and pull straight out without twisting to prevent connector damage.
Usage recommendations
For reliable performance, use this OM5 LC–LC cable with compatible InfiniBand transceivers and maintain clean connector endfaces. Avoid tight bends and excessive pulling force during installation. Label both ends of the cable to simplify future maintenance and ensure correct polarity when replacing or re-routing connections.
