Fibre optic cable EFB Elektronik O0387.20 20 m 2x SC 2x LC

The EFB Elektronik O0387.20 is a 20 m OS2 single-mode fibre optic cable fitted with two SC connectors on one end and two LC connectors on the other. With a 9 µm core diameter and support for full-duplex links, this cable is intended for high-speed point-to-point optical transmission with low attenuation and controlled dispersion. The cable assembly is suitable for structured cabling in environments such as data centres, server rooms and telecommunication racks where single-mode links are required over longer distances.

Advantages

This fibre optic cable provides reliable single-mode transmission over a 20 m distance and is equipped with industry-standard SC and LC connectors for wide compatibility with network equipment. The 9 µm core diameter (OS2) reduces modal dispersion and supports low-loss connections, while the full-duplex configuration allows simultaneous bidirectional data flow. The combination of SC and LC terminations simplifies integration between devices that use different connector types without additional adapters.

Suitable for

• Interconnecting network equipment in data centres and server rooms
• High-performance networking links between switches, routers and optical transceivers
• Rack-to-rack or equipment-to-equipment optical connections
• Telecommunications and structured cabling backbones requiring single-mode fibre

Key specifications

• Length: 20 m
• Fibre type: OS2 single-mode
• Core diameter: 9 µm
• Connectors: 2x SC to 2x LC
• Transmission mode: full duplex

How to use

Install the cable by connecting the SC and LC connectors to the corresponding ports on your network devices or optical transceivers. Ensure connectors are clean before mating to avoid signal loss; use an appropriate fibre cleaning tool or lint-free wipes and isopropyl alcohol if necessary. Route the cable avoiding tight bends and mechanical stress to maintain the specified bend radius and to prevent microbends. Secure the cable within racks or cable managers to prevent strain on the terminations and to preserve long-term link quality.

Usage recommendations

Verify compatibility of device ports and transceiver types before installation, and perform an optical loss test or continuity check after connecting to confirm acceptable signal levels. Store and handle the cable according to standard single-mode fibre practices to prevent contamination and physical damage.
