LetLinkSo 40G QSFP+ to QSFP+ Passive DAC Patch Cable is professionally designed for short-range high-speed network interconnection in modern data centers and enterprise environments.

Adopting the standard 40GBASE-CR4, 40GbE QDR and 100Ω twinax architecture, this QSFP+ passive cable delivers stable 40Gbps data transmission with passive design, bringing ultra-low latency and extremely low power consumption, which is an ideal high-efficiency alternative to traditional optical module solutions.

We attach great importance to safety and environmental protection: All materials of the product comply with RoHS environmental directives, and the cable passes UL CL2 75℃ safety certification. Adopting eco-friendly PVC jacket, silver-plated solid copper conductors and PE dielectric, it is non-toxic and fully meets the safety standards of global data centers, equipment rooms and cabinets.
To eliminate user selection troubles, we clearly mark the total length and effective cable length, making cabinet wiring more accurate and reasonable.
Compliant with MSA multi-source agreement, this QSFP+ cable fiber supports hot-swappable plug-and-play, and is universally compatible with mainstream brand devices including Cisco, Ubiquiti UniFi, Meraki, Mikrotik, Intel, Fortinet, Netgear and TP-Link. The dual-shielded structure (AL-Mylar + braided shielding) effectively resists signal interference and crosstalk, ensuring stable signal transmission in high-density wiring environments.

With high-purity copper core and durable structure, this qsfp patch cable is wear-resistant and reliable for long-term use. It is widely applied to switches, servers, NAS, firewalls, NICs and other equipment with QSFP+ ports, covering data centers, enterprise server rooms, storage networks and other scenarios, providing stable, economical and professional high-speed connection solutions.
