EFB-Elektronik duplex jumper LC-E2000 9/125µ OS2 LSZH geel 2,0mm 1m O0364.1

For data centre technicians and network engineers who need a reliable fibre link between LC and E2000 interfaces, this 1-metre duplex jumper connects switches, patch panels, or media converters in high-density fibre environments. The single-mode OS2 fibre supports long-distance transmission with low attenuation, while the yellow LSZH jacket is halogen-free for safer use in enclosed spaces.

Key specifications

• Fibre type: Single-mode OS2
• Core/cladding diameter: 9/125 µm
• Connectors: LC duplex to E2000 duplex, UPC polish
• Cable length: 1 m
• Cable diameter: 2.0 mm
• Jacket material: LSZH
• Cable colour: Yellow
• Insertion loss: ≤ 0.3 dB
• Return loss: ≥ 50 dB
• Operating temperature: -20°C to +70°C

Why choose it

The E2000 connector features an integrated protective shutter, keeping the ferrule clean when unmated and reducing the risk of contamination. Combined with low insertion loss and a bend-insensitive OS2 fibre, this jumper maintains stable performance in dense patching areas.

Ideal use cases

• Connecting LC-based equipment to E2000 patch panels
• Telecom central offices and data centres
• Long-distance backbone links where OS2 fibre is specified

Good to know

The LSZH jacket emits low smoke and no halogen gases in a fire, making it suitable for enclosed spaces with strict safety requirements. The 2.0 mm diameter keeps the cable flexible while still protecting the fibres.
