Fibre optic cable Alcasa LW-820LC5 20 m LC Green

The Alcasa LW-820LC5 20 m LC Green is an OM5 multimode fibre optic patch cable with LC connectors on both ends and a 50 µm core diameter. Designed for high-density networking environments, this 20-metre cable provides stable, low-loss connections for short- to medium-distance links. The cable jacket is coloured green to indicate OM5 specification and to simplify identification within cabling infrastructure. It is suitable for structured cabling in data centres, server rooms and telecom racks where multimode performance and LC termination are required.

Advantages

The OM5 50 µm core supports wideband multimode transmission and improved modal bandwidth compared with older multimode types, enabling higher aggregate data rates over short distances. LC connectors provide a compact duplex termination that is widely compatible with modern transceivers and patch panels. The 20 m length reduces the need for additional patching and intermediate splices in typical installation layouts, while the standardized green jacket eases visual management of multimode links.

Suitable for

• Interconnecting network switches, servers and transceivers in data centres
• Short- to medium-range multimode links in enterprise LAN and campus networks
• High-performance computing clusters and SAN interconnects that use multimode optics
• Patch panel to equipment connections in telecom racks and server rooms

Key specifications

• Fibre type: OM5 multimode
• Core diameter: 50 µm
• Connector type: LC to LC, duplex
• Length: 20 m
• Jacket colour: Green (OM5 identifier)
• Typical insertion loss: low-loss multimode performance (installation-dependent)

How to use

Connect each LC connector to the corresponding LC port on transceivers, patch panels or equipment, ensuring proper alignment of duplex orientation and polarity. Avoid excessive bending of the fibre; follow the minimum bend radius recommended for multimode fibre during routing and cable management. Secure the cable along trays or in cable managers to prevent strain on the connectors and to maintain stable attenuation characteristics over time.

Recommendations

When installing the OM5 fibre, verify connector cleanliness before mating and use appropriate dust caps when ports are not in use. Test the link after installation with suitable multimode test equipment to confirm loss and polarity. For environments requiring longer single-span distances or single-mode optics, consider selecting an appropriate fibre type and transceiver combination instead of multimode cabling.
