INFRALAN A-DQ(ZN)B2Y OM4 4G Outdoor Fiber Optic Cable, 4 Fibers, 50/125µm, Black, 5.8mm, 2000N A4M4F1

For outdoor backbone installations where high bandwidth and mechanical robustness are non-negotiable, this INFRALAN fiber optic cable delivers OM4 multimode performance in a compact 5.8 mm black polyethylene jacket. It contains 4 fibers in a loose tube construction, ready for direct burial or duct deployment in campus, industrial, or telecom networks.

• Cable designator: A-DQ(ZN)B2Y
• Outer jacket: Polyethylene (PE), black
• Cable diameter: 5.8 mm
• Max. tensile strength during installation: 2000 N
• CPR fire class: Fca
• Bandwidth: 4700 MHz·km @ 850 nm, 500 MHz·km @ 1300 nm
• Attenuation: ≤ 2.3 dB/km @ 850 nm, ≤ 0.6 dB/km @ 1300 nm
• Operating temperature: -20 °C to +70 °C
• Installation temperature: -5 °C to +50 °C
• UV resistant
• Non-metallic strain relief (glass yarns)

Why choose it

The OM4 grade supports 10G, 40G, and 100G Ethernet up to 550 m at 850 nm, making it future-proof for high-speed outdoor links. The 2000 N installation tensile rating and rugged PE jacket allow pulling through ducts or direct burial without compromising the fibers. The Fca CPR classification means no fire performance determined, suitable for outdoor use where fire regulations are less stringent.

Ideal use cases

• Campus backbone connections between buildings
• Industrial Ethernet and fieldbus networks
• Telecom outdoor distribution
• FTTA (fiber to the antenna) applications

Good to know

The loose tube design protects fibers from moisture and mechanical stress, and the non-metallic construction eliminates grounding and lightning concerns. The cable is UV resistant for long-term outdoor exposure. Always follow the specified installation temperature range to avoid jacket cracking.
