FAQs

Q: Is this cable active or passive?
A: It is a passive twinax CX4 cable with no active components, offering near-zero latency and zero power consumption.

Q: What devices are compatible?
A: Any switch, server NIC, or HBA with CX4 (SFF-8470) ports that supports 10GBASE-CX4 per IEEE 802.3ak.

Q: How is this different from SFP+ DAC cables?
A: CX4 uses SFF-8470 connectors and 10GBASE-CX4 ports, while SFP+ DAC uses SFP+ cages. They are not interchangeable.

Q: Can it be used for InfiniBand?
A: Some environments use CX4-format cables for legacy InfiniBand 4x links, but verify your device and protocol compatibility before deployment.
