Optical patch cable duplex OEM LC–SC 50/125 µm OM3 15 m

Duplex optical patch cable OEM LC–SC 50/125 µm OM3 15 m is a multimode fibre assembly designed for short-range high-speed networks. It features an LC connector on one end and an SC connector on the other, using 50/125 µm OM3 fibre optimized for 10Gb/s and higher multimode links. With a 15 metre length, this cable is suitable for interconnecting patch panels, network switches, transceivers and other active equipment in data centres, server rooms and campus LANs while maintaining low insertion loss and stable performance.

Advantages

This duplex LC–SC patch cable provides a standardized multimode OM3 fibre geometry that supports high bandwidth and low modal dispersion for short-reach applications. The mixed connector pair allows flexible termination to devices with LC and SC ports without additional adapters. A 15 m length offers convenient routing across racks and cabinets, reducing the need for intermediate splices. The cable is intended to deliver repeatable, low-loss connections appropriate for patching and equipment moves, additions and changes in professional network environments.

Suitable for

• 10 Gigabit Ethernet links and other multimode short-range connections
• Patching between LC and SC ports on switches, transceivers and patch panels
• Data centre and server room fibre management
• Campus LAN backbone segments and telecom equipment interconnects

When it may not be suitable

This cable uses OM3 multimode fibre with a 50/125 µm core/cladding profile, which is optimized for short-reach multimode applications; it is not intended for singlemode long-haul transmission. If your network requires long-distance links or singlemode transceiver compatibility, a singlemode fibre cable would be more appropriate. Also, environments that require armoured or outdoor-rated cabling should use purpose-built assemblies with the required mechanical protection and environmental ratings.

Key specifications

• Fibre type: Multimode OM3, 50/125 µm
• Configuration: Duplex
• Connector A: LC
• Connector B: SC
• Length: 15 m
• Typical application: Short-range high-speed links (e.g., 10Gb/s)
• Polish/connector style: Standard multimode polished connectors

How to use

Route the duplex patch cable between the equipment ports, ensuring the LC connector mates with LC receptacles and the SC connector with SC receptacles. Avoid tight bends; maintain the manufacturer's recommended minimum bend radius for multimode fibre to prevent increased attenuation. Use proper cable management in racks and patch panels to prevent strain on connectors and to keep bend radii compliant. Inspect connector endfaces for contamination and clean with fibre-optic cleaning tools if necessary before making connections. Verify link performance with appropriate testing equipment after installation.

What to consider before purchase

• Confirm that connected devices have matching LC and SC ports or that adapters are available
• Verify that OM3 multimode fibre meets the distance and bandwidth requirements for your application
• Check whether a different jacket type (armoured, LSZH, outdoor) is required for your environment
• Ensure 15 m length is suitable for rack and rack-to-rack routing without excess slack

Usage recommendations

For reliable performance, avoid sharp bends, protect connectors from dust when not in use, and perform endface cleaning before mating. Label both ends for easier identification in patching environments and verify link loss with a certified tester after installation.
