Product information

Description

The BlueOptics SFP2121BU20MK InfiniBand fibre optic cable 20 m LC Yellow is a single-mode OS2 patch cable designed for high-speed data transmission in networking and data centre environments. With LC connectors and a 20 metre length, this yellow cable provides a cost-effective and reliable link between InfiniBand devices, switches, transceivers and patch panels. The cable construction uses a 125 µm core diameter fibre suitable for long-distance, low-loss signal propagation typical of single-mode installations.

Advantages

This InfiniBand fibre optic cable combines single-mode OS2 performance with LC connector compatibility to support low attenuation and high bandwidth over its 20 m length. The yellow jacket provides industry-standard colour coding for single-mode runs, making identification and cabling management easier. The LC connector endfaces are designed to ensure stable mating with transceivers and adaptors, reducing insertion loss and return loss in typical data centre layouts.

Suitable for

  • Connecting InfiniBand host channel adapters to switches and switches to switches in HPC clusters
  • Patch connections in data centre racks and network cabinets
  • Linking transceivers and optical modules that use LC interfaces
  • Single-mode backbone and long-reach point-to-point connections up to moderate distances

Key specifications

  • Fibre type: Single-mode OS2
  • Length: 20 metres
  • Connector type: LC to LC
  • Fibre core diameter: 125 µm
  • Jacket colour: Yellow (single-mode identification)

How to use

Route the cable between equipment while avoiding sharp bends and tight cable ties; maintain the manufacturer’s recommended minimum bend radius. Clean connector endfaces before insertion using appropriate fibre cleaning tools to minimise insertion loss. Insert LC connectors into compatible ports or adaptors until they click into place, and label both ends if required for easier identification in patch panels. When removing the cable, depress the release tab on the LC connector and gently withdraw to avoid damaging the ferrule.

Usage recommendations

For optimal performance in data centres and HPC environments, use this OS2 single-mode cable with compatible InfiniBand transceivers and maintain a dust-free environment for connector endfaces. Avoid tight bundling with power cables and follow standard fibre handling practices to preserve signal integrity.
