Axiom 100G QSFP28 passive DAC cable two metres long with twin connectors

Axiom

Axiom MCP1600-E002E-AX 100G QSFP28 DAC Cable 2m

SKU CH-VK5F-DK903 MPN MCP1600-E002E-AX

100G QSFP28 passive DAC cable connects switches and routers over 2 metres with Mellanox-coded compatibility

  • 100 Gb/s throughput for high-density links
  • 2 metre reach fits standard rack spacing
  • Mellanox-coded firmware ensures switch recognition
  • MSA-compliant twinax construction works across vendors
  • Pre-serialised part number avoids inventory conflicts

What this cable is and who needs it

The Axiom MCP1600-E002E-AX is a 100G QSFP28 passive direct attach copper cable built for short reach links between switches, routers and servers. It suits data centre operators who need a cost effective, low latency interconnect for 100GbE or InfiniBand EDR fabrics. Buyers who want longer reach or active optical cables should look elsewhere.

The specification that decides fit

This twinax assembly uses a 100GBASE CR4 electrical interface and complies with the multi sourcing agreement so it works in any MSA compliant QSFP28 port. Each end is pre coded for Mellanox equipment while remaining fully functional in other MSA platforms. If your hardware requires an active or optical module this passive copper cable will not meet the requirement.

Behaviour under sustained load

Because the cable is completely passive it adds no active components that can throttle or overheat during continuous 100Gbps transmission. Signal integrity is maintained by the twinax construction over the full 2 metre length without the power draw or firmware complexity of active alternatives. The link remains stable as long as the host ports stay within their thermal and electrical limits.

Highlights

  • 100 Gb/s throughput for high-density links
  • 2 metre reach fits standard rack spacing
  • Mellanox-coded firmware ensures switch recognition
  • MSA-compliant twinax construction works across vendors
  • Pre-serialised part number avoids inventory conflicts

Questions about this item

What does 100GBASE-CR4 mean for throughput when the cable is plugged in?

The cable carries four lanes at 28 Gb/s each, delivering 100 Gb/s of aggregate bandwidth between two QSFP28 ports.

Which electrical standard does the passive twinax use and what distance limit does it impose?

It follows the 100GBASE-CR4 specification for passive copper, which supports reaches up to 2 m.

What physical slot and latch style does the MCP1600-E002E-AX need to mount securely?

Each end terminates in a standard QSFP28 module with a pull-tab latch that locks into any MSA-compliant QSFP28 cage.
