• Connectors: LC duplex to LC duplex, UPC polish
• Length: 3 meters (9.8 ft)
• Jacket: LSZH (Low Smoke Zero Halogen), yellow
• Insertion loss: ≤ 0.3 dB; return loss: ≥ 50 dB
• Attenuation: 0.35 dB/km @ 1310 nm, 0.25 dB/km @ 1550 nm
• Bend radius: ≥ 30 mm
• Operating temperature: -20°C to 70°C
• Compliance: RoHS, TIA/EIA-568-C.3, IEC 60794-2

Why choose it

The LSZH jacket emits low smoke and no halogen in case of fire, protecting both equipment and personnel in enclosed spaces. Precise LC connectors and tight tolerances deliver consistent performance for 1G/10G/25G/40G Ethernet and Fibre Channel applications.

Ideal use cases

• Data center interconnects between switches and patch panels
• Telecom central offices and server rooms
• Enterprise backbone links requiring low attenuation
• Any environment where LSZH is mandated for safety

Good to know

Each cable is individually tested to ensure compliance with insertion loss and return loss specifications. The duplex clip allows easy polarity reversal. The yellow jacket provides high visibility and quick identification of single-mode fiber.
