## Summary description

The Alcasa LW-U820LC4 is a 20 m OM4 fibre optic cable featuring 2x LC connectors on both ends. With a core diameter of 50 µm, it supports full duplex communication, ensuring high-speed data transfer and reliable connections. Ideal for data centers and high-performance networks, this cable provides excellent signal quality and minimal loss, making it a perfect choice for demanding applications.

## Long description

The Alcasa LW-U820LC4 20 m OM4 fibre optic cable with 2x LC connectors on each end is designed for high-speed, full-duplex optical links. With a 50 µm core diameter and violet jacket colour, this cable supports multimode transmission suitable for modern data centre and enterprise networks where low attenuation and stable signal quality are required over medium distances. The 20 m length provides flexibility for rack-to-rack or equipment-to-equipment connections while the LC duplex connectors enable compact port density and reliable mating.
Advantages
This OM4 fibre cable offers low insertion loss and modal bandwidth suitable for 10 Gbps and higher multimode applications over typical data centre distances. The duplex LC connector arrangement ensures correct polarity for full-duplex communication and straightforward installation. The violet jacket makes the cable easy to identify among other network cabling, and the 20 m length reduces the need for additional patching hardware in many layouts.
Suitable for
 Data centre horizontal and rack-to-rack connections
 High-performance enterprise networks and server interconnects
 Multimode fibre links for 10 Gbps and short-reach 40/100 Gbps applications where OM4 is specified
 Patch panels and high-density LC port deployments
Key specifications
 Length: 20 m
 Fibre type: OM4 multimode
 Core diameter: 50 µm
 Connectors: 2x LC duplex on each end (full duplex)
 Jacket colour: violet
How to use
Route the Alcasa LW-U820LC4 cable through cable management channels or racks to reach the intended network equipment. Power down or follow hot-plug procedures per equipment vendor guidance if required, then insert each LC connector into corresponding LC ports ensuring correct polarity for transmit and receive pairs. Secure the cable along trays or tie points to avoid strain on connectors and maintain bend radii recommended for multimode fibre. Test the link with suitable fibre testers or network equipment diagnostics to verify optical power levels and signal integrity after installation.
Usage recommendations
Avoid sharp bends and excessive tensile stress; maintain manufacturer-recommended minimum bend radius for OM4 multimode fibre. Use dust caps when connectors are not mated and perform visual inspection or cleaning prior to insertion to reduce insertion loss. For critical links, validate performance with optical loss and end-to-end testing after deployment.
