## Summary description

The BlueOptics SFP3133EU20MK is a 20 m OM3 fibre optic cable featuring LC and ST connectors. It has a core diameter of 50 µm and supports full duplex communication, making it ideal for high-speed data transmission in networking applications.

## Long description

The BlueOptics SFP3133EU20MK 20 m LC ST OM3 fibre optic cable is a duplex multimode patch cord designed for high-speed data transmission. It uses laser-optimized multimode fibre (OM3, 50/125 µm) with LC/UPC to ST/PC connectors, an aqua LSZH jacket and is specified for 850 nm optical signals. The cable is suitable for connecting patch panels, transceivers and other active equipment requiring reliable full-duplex fibre links over short to medium distances.
Advantages
This OM3 duplex fibre cord provides low attenuation (approximately 3.5 dB/km) and high return loss, with the option to further optimize return loss through connector polish selection. The cable uses branded multimode fibres and precision connectors with zirconia ceramic ferrules for stable, repeatable mating and up to 1500 mating cycles. Production testing includes interferometer and OTDR measurements, and each unit is shipped with an input loss and return loss measurement protocol. The LSZH jacket reduces smoke and eliminates halogen release in case of fire, meeting a range of industrial safety standards.
Suitable for
 Connecting optical transceivers and network switches in data centres and server rooms
 Patch panel to equipment connections in LAN and enterprise networks
 Short- to medium-range multimode links at 850 nm (10 GbE and similar applications)
 Environments requiring low-smoke, halogen-free cabling (LSZH)
Key specifications
 Fibre type: OM3 multimode (50/125 µm, laser-optimized)
 Length: 20 metres
 Connector types: Duplex LC/UPC to ST/PC
 Wavelength: 850 nm transmission optimized
 Attenuation: ~3.5 dB/km (typical)
 Jacket: LSZH (low-smoke, zero-halogen), aqua colour
 Duplex full-duplex operation
 Connector ferrule: zirconia ceramic, high mating cycle durability
How to use
Inspect connector endfaces before installation and clean them with an appropriate fibre cleaning tool if necessary. Route the duplex cable avoiding sharp bends and excessive tensile stress; respect the manufacturer’s minimum bend radius. Plug the LC connector into the LC port and the ST connector into the ST port or transceiver, ensuring proper alignment and secure latching. Verify the link using optical diagnostic tools or the equipment’s link/activity indicators and consult the supplied measurement protocol for expected input loss and return loss values.
Usage recommendations
For best performance, keep connectors capped when not in use, perform routine endface inspections, and avoid running the cable near strong electromagnetic interference sources. Use the cable within its specified bend radius and replace any connector with visible damage. For permanent or outdoor installations, select appropriate protective routing or additional armouring as required.
