Product information

Description

The BlueOptics SFP3131FU20MK is a 20 m OM4 duplex fibre optic patch cord with LC/UPC connectors on both ends, designed for InfiniBand and other high-speed multimode links. The cable uses 50/125 µm laser-optimized multimode fiber (LOMMF) optimized for 850 nm transmission, housed in a flame-retardant LSZH jacket and coloured magenta for easy identification. It supports full-duplex communication and is supplied with measured insertion loss and return loss values to ensure reliable performance.

Advantages

This OM4 LC-LC duplex cable offers low attenuation (typical 2.5 dB/km), low insertion loss and high return loss for stable, high-bandwidth links. Connectors incorporate zirconia ceramic ferrules rated for up to 1500 mating cycles and are manufactured by reputable OEMs. The LSZH jacket reduces smoke and avoids halogen emission in case of fire, while production testing with interferometer and OTDR provides documented quality control and a measurement protocol with each unit.

Suitable for

  • InfiniBand interconnects and high-speed multimode links
  • Patch panel to transceiver or transceiver-to-transceiver connections
  • Data centre horizontal and rack-to-rack links requiring OM4 performance
  • Short-reach multimode applications at 850 nm

Key specifications

  • Fiber type: OM4 laser-optimized multimode fiber (50/125 µm)
  • Length: 20 m
  • Connector type: Duplex LC/UPC to LC/UPC
  • Polarization: Full duplex (duplex patch cord)
  • Typical attenuation: 2.5 dB/km at 850 nm
  • Jacket: LSZH (low smoke zero halogen), magenta colour
  • Operational wavelength: 850 nm
  • Connector durability: up to 1500 mating cycles (zirconia ferrule)

How to use

Uncoil the BlueOptics LC-LC OM4 duplex cable gently to avoid kinks and lay it along the intended routing path. Align and insert each LC connector into the corresponding LC port on patch panels or optical transceivers until a positive click is felt. Ensure transmit (TX) and receive (RX) orientation is correct for full-duplex operation. Avoid tight bends below the specified minimum bend radius and secure the cable using appropriate cable management to prevent mechanical stress. Retain the supplied measurement protocol for reference and verification during installation or troubleshooting.

Usage recommendations

Store and handle the cable in a clean environment to keep connector endfaces free of dust and contamination. Use a fibre inspection tool or cleaning cassette before mating connectors. Maintain bend radius guidelines and avoid repeated tight bending to preserve low insertion loss. For critical links, refer to the supplied OTDR/interferometer measurements and perform post-installation testing to verify link performance.
