## Summary description

The BlueOptics SFP3333EU0.5MK is a 0.5 m InfiniBand fibre optic cable featuring ST connectors and OM3 fibre type. It supports full duplex communication with a core diameter of 50 µm, making it ideal for high-speed data transfer in networking applications.

## Long description

The BlueOptics SFP3333EU0.5MK is a 0.5 m InfiniBand fibre optic patch cord with duplex ST/PC to ST/PC connectors and OM3 (50/125 µm) multimode construction in aqua jacket. Designed for 850 nm transmission, this ST–ST OM3 duplex cable supports full-duplex high-speed data transfer between patch panels, optical transceivers and other network equipment. The cable features a flame-retardant LSZH outer jacket and is manufactured using branded multimode fiber and precision zirconia ferrules for consistent optical performance.
Advantages
This 0.5 m OM3 ST–ST duplex fibre offers low attenuation (3.5 dB/km nominal) and optimized return loss through high-quality polishing options. Connectors use ceramic zirconia ferrules and brand-name components for up to 1500 mating cycles. Each cable is tested with interferometer and OTDR methods and supplied with measured insertion loss and return loss values. The LSZH jacket reduces smoke and avoids halogen emissions in case of fire, meeting common industry safety norms.
Suitable for
Interconnecting InfiniBand or Ethernet transceivers and modules within racks or between nearby equipment
Patch panel to patch panel connections in data centres and server rooms
Short-reach multimode links requiring OM3 performance at 850 nm
Environments where low-smoke, zero-halogen cabling is required
Key specifications
Length: 0.5 m
Connector type: ST/PC to ST/PC duplex
Fiber type: OM3 multimode (50/125 µm)
Operating wavelength: 850 nm
Attenuation: approx. 3.5 dB/km
Jacket material: LSZH (low smoke zero halogen)
Color: Aqua
Typical connector durability: up to 1500 mating cycles
Tested with interferometer and OTDR; measurement protocol included
How to use
Install the BlueOptics SFP3333EU0.5MK by aligning and inserting each ST connector into the corresponding ST/PC port on the transceiver or patch panel until it clicks or seats firmly. Ensure connectors are clean before mating to avoid contamination and insertion loss. Route the duplex cable with gentle bends only, respecting the manufacturer’s minimum bend radius to avoid microbending losses. For best results, verify link performance using appropriate optical test equipment after installation.
Usage recommendations
Clean connector endfaces with approved fibre cleaning tools before each connection. Avoid tight bends and mechanical strain; secure the cable to prevent tugging. Choose OM3 duplex patch cords of suitable length to minimise excess slack in rack and cabinet installations. Keep the supplied measurement protocol for record-keeping and troubleshooting.
