KeepFly Fiber OM4 LC to LC Patch Cable 30m – 40G/100G MMF Duplex, LSZH Aqua

Overview

Designed for data centers, SANs, and enterprise networks, the KeepFly Fiber OM4 LC to LC Patch Cable 30m blends speed with reliability. The duplex 50/125 μm multimode link delivers strong signal integrity in demanding environments, making it a solid option for high-speed 40G and 100G applications. A zirconia ceramic fiber core helps minimize insertion loss while preserving high return loss, and the aqua LSZH jacket adds a visible, fire-safe layer for shared spaces.

Performance you can trust

• Low insertion loss (≤ 0.3 dB) and high return loss (≥ 30 dB) support clean, stable transmissions.
• Multimode duplex 50/125 μm fibers enable robust data transmission across short and mid-range links.
• Maximum transmission distances at 850 nm: up to 550 m for 1 Gb, 300 m for 10 Gb and 40 Gb, and 200 m for 100 Gb, with a bandwidth of 2000 MHz-km.

Secure, flexible installation

• Embossed A/B position names on the duplex clip and jacket tag rings simplify path identification during installation and troubleshooting.
• The cable is bendable with a 7.5 mm minimum bend radius, making it easier to route in dense SAN cabinets or compact racks.

Safety, compatibility, and use cases

• LSZH aqua jacket provides fire safety with low smoke emission for indoor deployments and shared spaces.
• Backward compatible with common Ethernet and Fibre Channel standards, and compatible with 40G/100G transceivers and NICs for flexible deployments.
• Ideal for data-center backbones, server racks, and high-density installations where multiple elbows or tight footprints are present.

What to expect in deployments

Length options range from compact 0.2 m up to 200 m, with 30 m serving as a practical mid-length for rack-to-rack links. The combination of low loss, solid reliability, and clear identification aids helps teams organize complex networks without sacrificing performance. While results depend on the broader network design and equipment, this patch cable is built to support high-speed links with consistent signal quality across typical data-center scenarios.
