Cavo in fibra ottica EFB Elektronik O0939.25 E-2000 (LSH) SC G.657.A1 25 m giallo

The EFB Elektronik O0939.25 is a 25 m fibre optic patchcord with an E-2000 (LSH) connector on one end and an SC connector on the other. It uses G.657.A1 single-mode fibre with a 9 µm core diameter and is supplied in yellow for clear identification in structured cabling installations. The cable is intended as the short link between passive interfaces and active device ports in data and telecommunication networks.

Advantages

This patchcord combines an E-2000 (LSH) precision connector and a standard SC connector to provide a reliable single-mode connection. The G.657.A1 fibre type offers improved bend performance compared with standard single-mode fibres, while the 9 µm core ensures compatibility with common single-mode equipment. The 25 m length allows for flexible routing within racks, cabinets and patch panels.

Suitable for

• Interconnecting optical equipment in LAN and telecom racks
• Patch panels and distribution frames
• Connections between active devices and passive interfaces
• Environments requiring improved bend performance (G.657.A1)

How to use

Route the fibre patchcord between the active device port and the passive interface or patch panel, ensuring connectors are clean and dust-free before insertion. Align and insert the E-2000 (LSH) and SC connectors into their respective ports until they click or seat securely. Avoid sharp bends and protect the cable from crushing; follow standard handling and safety practices for single-mode fibre to maintain optical performance.

Recommendations

Clean connector endfaces with appropriate fibre cleaning tools before each connection, use cable management to maintain minimum bend radius for G.657.A1 fibre, and store unused ends with protective caps to prevent contamination.
