Fibre optic cable Alcasa LW-U815LC3 15 m 2x LC

The Alcasa LW-U815LC3 15 m OM3 fibre optic cable with 2x LC connectors on both ends is designed for high-speed, short-to-medium distance network links. With a 50 μm multimode core and OM3 performance, the cable supports full duplex data transmission and is appropriate for structured cabling in data centres, server rooms and telecom racks. The cable jacket and connector design provide consistent optical performance and low insertion loss for reliable signal integrity.

Advantages

This 15 m fibre optic cable provides OM3-class bandwidth for high-speed multimode applications and enables reduced modal dispersion over typical link distances. Dual LC connectors at each end allow easy connection to LC duplex ports widely used on SFP+/SFP28 and QSFP modules and active equipment. The 50 μm core diameter ensures compatibility with multimode transceivers and simplifies installation in patch panels and network switches. Constructed for stable optical characteristics, the cable offers low attenuation and minimal return loss in common enterprise and data centre environments.

Suitable for

• Data centre patching between switches, servers and optical modules
• Server room backbone and horizontal cabling
• Connecting SFP+/SFP28/QSFP transceivers and LC duplex ports
• High-speed multimode links for storage and virtualization environments

Key specifications

• Length: 15 m
• Fiber type: OM3 multimode
• Core diameter: 50 μm
• Connector type: LC duplex on both ends (2x LC)
• Mode: Full duplex
• Typical use: Short-to-medium distance multimode links

How to use

Route the cable through the cable management system or along the intended path ensuring gentle bends and avoiding tight radii to prevent increased attenuation. Insert the LC duplex connectors into matching LC ports until they click to secure the connection. For full duplex operation, ensure transmit and receive pairs are correctly aligned between devices. When making changes, always power down or follow hot-swap procedures recommended by the connected equipment to avoid damage to transceivers.

Usage recommendations

Store and handle the cable in a clean environment to avoid contamination of connector endfaces. Clean connector endfaces before mating using approved fiber cleaning tools. Maintain bend radius greater than the manufacturer’s minimum (typically several times the cable diameter) and avoid crushing or excessive pulling. Use proper strain relief and routing in racks or patch panels to preserve optical performance.
