Product Description
ST to SC multimode duplex fibre patch leads are used to connect older ST-terminated equipment to SC ports on switches, fibre patch panels, media converters and network hardware. Each lead provides paired transmit and receive channels in one duplex assembly, making it a practical choice for maintaining mixed-connector fibre networks across offices, comms rooms and campus environments.
Key Features
ST to SC duplex multimode fibre configuration
Available in OM1, OM2, OM3 and OM4 grades
Supports 62.5/125 and 50/125 multimode fibre requirements
LSZH outer sheath for indoor commercial installations
Short strain relief boots to help protect connector ends
100% optically tested before supply
Supplied individually bagged and labelled
Test report included with insertion loss details
Benefits
Connects legacy ST equipment to newer SC-based infrastructure
Duplex format keeps transmit and receive fibres paired together
Multiple OM grades allow the cable to match existing fibre plant
LSZH jacket supports safer indoor cable management
Factory testing gives added confidence before installation
Useful for repairs, replacements and staged network upgrades
Product Comparison
SC to SC multimode duplex - better suited when both ends of the link use SC ports, such as between SC patch panels and older network equipment.
ST to ST multimode duplex - used where both devices or panels still use ST bayonet-style connectors.
ST to SC singlemode duplex - similar connector format, but with OS1/OS2 fibre for longer-distance singlemode links rather than shorter multimode runs.
Cable Lengths and Performance
Available in a range of standard lengths and multimode grades. Distance support depends on the fibre type and network speed:
OM1: up to 275m at 1Gb, 33m at 10Gb
OM2: up to 550m at 1Gb, 82m at 10Gb
OM3: up to 300m at 10Gb, 100m at 40/100Gb
OM4: up to 400m at 10Gb, 150m at 40/100Gb
Who It's For
IT teams, network installers and maintenance engineers working with mixed ST and SC multimode fibre environments, particularly where older fibre panels or devices need to connect into newer SC-based network hardware.
FAQs
Can this connect an ST patch panel to an SC switch or media converter? Yes. It is designed for ST-to-SC multimode fibre links.
Is this cable singlemode or multimode? This product is multimode and is available in OM1, OM2, OM3 and OM4 grades.
Does it include a test certificate? Yes. The lead is optically tested and supplied with an insertion loss report.
What does LSZH mean? LSZH stands for low smoke zero halogen, a sheath type commonly used for indoor commercial cabling.
Should I choose OM3 instead of OM2? In many cases, yes. OM3 is backwards compatible with OM2 and supports higher-speed links over longer distances.

Note: Due to a low demand, OM2 Leads are now at a higher price than OM3 leads.
OM3 leads are backwards compatible with OM2 leads and will fulfil the same requirements.
