Product information

Description

The BlueOptics SFP3131FU2.5MK is a 2.5 meter InfiniBand fibre optic patch cord with duplex LC/UPC to LC/UPC connectors and OM4 (G50/125 µm) laser-optimized multimode fibre. Designed for data center and enterprise networking, the cable supports full-duplex 850 nm transmission with low attenuation and high return‑loss characteristics. The LSZH (low smoke zero halogen) jacket reduces smoke and prevents halogen release in the event of fire, making it suitable for confined or densely cabled environments.

Advantages

This OM4 LC–LC duplex patch cord offers low insertion loss (approx. 2.5 dB/km) and high return loss, with connector polish options that allow further optimization. Connectors use zirconia ceramic ferrules for reliable alignment and a long mating life of up to 1500 cycles. Cables are manufactured with branded multimode glass from established vendors and undergo interferometer and OTDR testing; each shipped cable includes a measurement protocol for input loss and return loss. The LSZH jacket improves fire safety compared with PVC jackets.

Suitable for

  • InfiniBand links in data centers and HPC clusters
  • Short-range multimode connections (server to switch, patch panel to transceiver)
  • High-density optical patch panels and cable management systems
  • Environments requiring low-smoke, halogen-free cabling

Key specifications

  • Length: 2.5 m
  • Fibre type: OM4 (G50/125 µm), laser-optimized multimode fiber
  • Connectors: Duplex LC/UPC to LC/UPC
  • Polish: UPC (polish optimized for low back reflection); APC option available for higher return loss where applicable
  • Wavelength: 850 nm multimode transmission
  • Attenuation: approx. 2.5 dB/km
  • Jacket: LSZH (low smoke zero halogen), flame-retardant
  • Durability: zirconia ceramic ferrule, up to 1500 mating cycles
  • Testing: interferometer and OTDR test measurements supplied with each cable

How to use

Verify that both ends of the duplex LC patch cord are clean and free of dust before installation. Align the LC connectors with the corresponding LC ports on transceivers, switches or patch panels and insert until a click confirms a secure connection. Ensure the correct polarity for duplex links (A to B) and route the cable through cable management to avoid tight bends; maintain the manufacturer’s minimum bend radius. After installation, verify link performance using appropriate diagnostic tools and compare measured insertion loss to the supplied measurement protocol.

Usage recommendations

Store and handle the fibre patch cord using protective caps on unused connectors. Clean connector endfaces with approved fibre cleaning tools before mating. Use LSZH cabling in enclosed spaces or where fire safety regulations recommend low-smoke, halogen-free materials. For distances or applications beyond multimode OM4 specifications, consider singlemode fibre or transceiver options appropriate for required reach.
