BlueOptics SFP3133FU2MK InfiniBand fibre optic cable 2 m LC ST

BlueOptics SFP3133FU2MK is an OM4 multimode fibre optic duplex patch cord with LC/UPC to ST/PC connectors and a 50/125 µm core/cladding design. The 2 m InfiniBand cable is intended for high-speed data transmission at 850 nm and provides full-duplex connections between patch panels, switches or optical transceivers. The jacket is LSZH and the cable is magenta-coloured, matching standard OM4 identification.

Advantages

This OM4 LC–ST duplex cable offers low attenuation (approximately 2.5 dB/km) and low insertion loss with high return loss. Connectors use zirconia ceramic ferrules from established manufacturers, rated for up to 1500 mating cycles. Cables are factory-tested with interferometer and OTDR and shipped with measurement protocols for insertion loss and return loss. The LSZH jacket reduces smoke and releases no halogens in case of fire.

Suitable for

• Data centre interconnects and InfiniBand links
• Patching between optical transceivers and patch panel ports
• High-speed short-reach links at 850 nm
• Environments requiring low-smoke, halogen-free cabling

Key specifications

• Fibre category: OM4 (laser-optimized multimode, G50/125 µm)
• Connectors: Duplex LC/UPC to ST/PC
• Length: 2 m (other lengths available on request)
• Wavelength: 850 nm
• Attenuation: ~2.5 dB/km
• Jacket: LSZH (flame-retardant, low smoke, halogen-free)
• Compliance: Telcordia GR-326-Core 4.4, IEC and RoHS standards

How to use

Inspect connectors and ports for dust before mating. Align the LC and ST connectors with their respective ports and insert until a secure connection is felt. For best performance avoid sharp bends and maintain the minimum bend radius specified by the manufacturer. When relocating or rerouting, disconnect by depressing the LC latch and pulling the ST connector sleeve as required; store with protective dust caps when not in use.

Usage recommendations

Use this OM4 LC–ST duplex cable for short-reach, high-bandwidth links within racks and between equipment in data centres. Select the appropriate length to avoid excess cable slack and follow handling guidelines to preserve low insertion loss and longevity of connectors.
