V2 Technologies 100GbE QSFP28 DAC Cable .5m Blue Pull Tab 2 in 1 accessory

SKU CH-G9MA-9DZH1

A 0.5 metre passive copper twinax cable delivers a 100 GbE link between QSFP28 ports with a blue pull tab for easy handling

  • Cost-effective 100G link between QSFP28 switch ports
  • Passive copper design minimises power and EMI consumption
  • IEEE 802.3, SFF-8665 and QSFP28 MSA compliant
  • Blue pull tab simplifies insertion and removal in dense racks
  • 5 m length with 30AWG twinax for short-reach rack connections

What it is and who it's for

This V2 Technologies accessory is a 100GbE QSFP28 direct-attach copper cable with a blue pull tab. It suits network engineers who need a short, passive link between compatible switch ports inside a rack or across adjacent racks. The half-metre length keeps cable management tidy in dense environments.

The spec that decides fit

The cable uses a 30AWG twinax assembly rated for 28.3125G bps per channel and terminates in a hot-pluggable 38-pin QSFP28 footprint. It follows IEEE 802.3, SFF-8665 and QSFP28 MSA standards, so it will only work where both ends present QSFP-100G ports that accept passive copper at this gauge.

Thermals noise and power draw

Passive construction means no active components draw extra power beyond the single 3.3V supply, keeping consumption at the lowest level for this speed. EMI is minimised by the compliant design, and the operating temperature range spans 0 to 70°C without a fan. No audible noise is produced in normal use.
