CE ST - SC Connector Multimode Duplex Fibre Patch Leads

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.
