Cabo de fibra ótica Helos 20 m OM4 LC/ST

The Helos 20m OM4 LC/ST fibre optic cable provides a 20-metre duplex link with LC connector on one end and ST connector on the other, designed for multimode networks. With a 50 µm core diameter and OM4 specification, the cable supports high-bandwidth, low-loss short- to medium-range transmissions suitable for modern data centre and enterprise environments. Its construction targets consistent signal integrity for applications that require reliable full-duplex communication.

Advantages

The OM4 multimode grade increases modal bandwidth and extends usable distance compared with lower multimode specifications, enabling higher data rates over the 20 m span. The LC connector offers a compact form factor for high-density patch panels while the ST connector provides a bayonet-style coupling commonly used in existing network infrastructures. The cable assembly is pre-terminated and tested to ensure proper optical continuity and reduced installation time.

Suitable for

• Short- to medium-range data centre interconnects
• Server-to-switch and switch-to-switch links in enterprise LANs
• High-speed multimode applications such as 10GbE and 40GbE (within OM4 range)
• Patch panel and backbone connections where mixed connector types are required

Key specifications

• Length: 20 metres
• Fiber type: Multimode OM4
• Core diameter: 50 µm
• Connector A: LC (duplex)
• Connector B: ST
• Mode: Full duplex
• Typical applications: Data centre patching, LAN backbone, equipment interconnects

How to use

Inspect both connectors and the cable for visible damage before installation. Route the cable following standard fibre handling practices: avoid sharp bends, keep bend radius within manufacturer guidelines, and secure with appropriate cable management to prevent strain. Insert the LC connector into the LC receptacle and the ST connector into the ST bayonet socket until it seats firmly. Verify link status and optical power levels with suitable test equipment after connection.

Recommendations

Store and handle the OM4 fibre cable in a dry, dust-free environment and use dust caps on unused connectors. For optimal performance, clean connector endfaces before mating and perform optical loss or continuity testing after installation. Choose routing paths that minimize mechanical stress and maintain the recommended bend radius for multimode fibres.
