Product Features
Technical Overview
This QSFP+ DAC cable operates at the 40GBASE-CR4 standard, delivering full 40 Gbit/s bandwidth across four lanes of copper twinaxial conductors. The passive design means no signal processing electronics are embedded in the cable assembly, resulting in lower power consumption and reduced heat generation compared to active optical cables or active DAC solutions.
The cable features industry-standard QSFP+ male connectors that support hot-pluggable installation in compatible network switches, routers, and servers. The twinaxial cable construction provides excellent electromagnetic interference (EMI) shielding and signal integrity for distances up to 13.1 ft (4m), making it ideal for within-rack and adjacent-rack connections in data centers.

FAQ
What is the maximum data transfer rate of this DAC cable?
This Axiom DAC cable supports the 40GBASE-CR4 standard, delivering a maximum data transfer rate of 40 Gbit/s. This bandwidth is achieved across four lanes of copper twinaxial conductors, providing sufficient throughput for high-speed network applications including data center interconnects, server-to-switch connections, and network aggregation links.
What network equipment is this cable compatible with?
This DAC cable is specifically engineered and tested for compatibility with Juniper network equipment. It features standard QSFP+ male connectors that interface with Juniper switches, routers, and servers supporting QSFP+ ports. The cable's passive design and electrical characteristics are optimized for reliable performance in Juniper-based network infrastructure.
What does 'passive' mean for this DAC cable?
A passive DAC cable contains no signal processing electronics or retiming circuitry within the cable assembly. This design results in lower power consumption, reduced heat generation, and typically lower cost compared to active DAC cables or active optical cables. Passive DAC cables are ideal for short-reach applications up to their specified maximum distance, which for this cable is 13.1 ft (4m) while maintaining 40 Gbit/s performance.
What is the cable length and type?
This DAC cable measures 13.1 ft (4m) in length and utilizes twinaxial (twinax) construction. Twinaxial cable consists of two inner conductors surrounded by a dielectric insulator, metallic shielding, and an outer jacket. This design provides excellent electromagnetic interference protection and signal integrity for high-speed data transmission over copper, making it suitable for data center environments where reliable 40 Gbit/s connectivity is required.
