Product Features
Technical Overview
This cable implements the 100GBASE-CR4 Ethernet standard using the QSFP28 form factor, supporting four lanes of 25 Gb/s to achieve an aggregate data rate of 100 Gbit/s. The twinaxial cable construction provides excellent signal integrity for short-reach connections up to 2 meters, making it ideal for top-of-rack switching, server-to-switch links, and intra-rack connectivity.
The QSFP28 connectors feature a hot-pluggable design that allows for easy installation and maintenance without powering down connected equipment. This passive DAC solution eliminates the need for separate optical transceivers and fiber patch cables, reducing both initial deployment costs and ongoing maintenance requirements.

FAQ
What type of cable is the Axiom SF-NDAAFF100G-002M-AX?
This is a 100GBASE-CR4 QSFP28 passive direct attach copper (DAC) cable. It uses twinaxial copper construction with QSFP28 connectors on both ends to provide a complete 100 Gbit/s connection solution between compatible network devices without requiring separate transceivers.
What is the maximum data transfer rate supported by this DAC cable?
The cable supports data transfer rates up to 100 Gbit/s (100 gigabits per second). It implements the 100GBASE-CR4 Ethernet standard using four lanes of 25 Gb/s each through the QSFP28 interface, making it suitable for high-bandwidth networking applications.
What devices are compatible with this QSFP28 DAC cable?
This cable is designed to work with network devices, routers, and switches that feature compatible QSFP28 ports. The Amphenol-compatible connector design ensures broad compatibility with equipment from various manufacturers that support the 100GBASE-CR4 standard over passive DAC connections.
What does 'passive' mean for this DAC cable?
Passive means the cable contains no active electronics or signal conditioning components. It relies on the electrical properties of the twinaxial copper construction to transmit signals up to 2 meters. This eliminates power requirements, reduces potential failure points, and typically results in lower latency compared to active cables.
