LEONI Kerpen I-V(ZN)HH 4G 50/125µm OM3 LSOH 2.8mm Aqua Fiber Optic Cable

In modern data centers and enterprise buildings, network engineers need a backbone cable that delivers high bandwidth while meeting strict fire safety codes. The LEONI Kerpen I-V(ZN)HH 4G 50/125µm OM3 LSOH cable answers that call: four multimode fibers in a sleek 2.8 mm aqua jacket, engineered for low smoke and zero halogen emissions. It supports 10 Gigabit Ethernet up to 300 meters, making it a solid choice for LAN and SAN infrastructures where performance and safety go hand in hand.

• Minimum bending radius (installation): 42 mm

Why choose it

This cable's LSOH jacket ensures minimal toxic smoke and corrosive gas in the event of fire, which is critical for public buildings, data centers, and confined spaces. The OM3 fiber supports high-speed protocols like 10GbE, and with an EMB of 2000 MHz·km, it can handle future upgrades to 40G and 100G over short distances. The 2.8 mm diameter and tight bend radius make installation easy in dense racks and cable trays.

Ideal use cases

• Backbone cabling in data centers and server rooms
• Structured cabling in commercial buildings with strict fire regulations
• High-speed LAN and SAN connections
• Riser and plenum spaces where low smoke and zero halogen are required

Good to know

The cable is supplied in bulk lengths; connectors are not pre-installed. It is designed for indoor use only. The aqua jacket color is the industry standard for OM3 multimode fiber, allowing for quick identification in the field.
