Fibre optic cable EFB Elektronik O0937.20 — OS2, 20 m, E-2000 (LSH) to LC, 9 µm, full duplex, yellow

EFB Elektronik O0937.20 is a 20 m single-mode fibre optic cable built for low-loss, reliable optical links. The cable uses OS2 graded single-mode fibre with a 9 µm core diameter and terminates in an E-2000 (LSH) connector on one end and an LC connector on the other, providing full duplex capability. It is intended for high-speed data transmission in backbone links, telecommunication racks and structured cabling environments where consistent signal quality and low attenuation are required.

Advantages

The cable offers stable single-mode performance with a 9 µm core optimized for long-distance and high-bandwidth optical transmission. E-2000 (LSH) to LC termination provides compatibility with equipment using these common interfaces while the full duplex configuration enables simultaneous bidirectional data flow. The 20 m length provides flexible routing between racks and equipment without additional splices, and the yellow jacket makes the cable easy to identify in multi-fibre installations.

Suitable for

• Data centre backbone and inter-rack connections
• Telecommunications equipment links
• Patch panels and optical distribution frames
• LAN/WAN links requiring single-mode OS2 performance
• High-speed optical interfaces with E-2000 or LC ports

Key specifications

• Fibre type: single-mode OS2
• Core diameter: 9 µm
• Length: 20 m
• Connector A: E-2000 (LSH)
• Connector B: LC

How to use

Install the cable by connecting the E-2000 (LSH) end to the matching socket on the transmitting or receiving device and insert the LC connector into the corresponding port on the opposite device or patch panel. Ensure connectors are clean before insertion to maintain low optical loss. Route the cable following standard bend radius guidelines and secure it with cable management hardware to avoid strain or microbending. For diagnostic checks, verify continuity and insertion loss with appropriate fibre test equipment after installation.

Recommendations

Prior to installation, inspect and, if necessary, clean connectors with approved fibre cleaning tools. Avoid tight bends and sharp kinks; maintain the manufacturer’s minimum bend radius. Use labelled cable management and strain relief to preserve connector alignment and optical performance during operation.
