    • Is this a passive or active cable?
  • It is a passive cable, meaning it does not require additional power for signal boosting.
    • What is the data transfer rate of this cable?
  • It supports 40Gbps (Gigabits per second) transmission speed.
    • Which Cisco devices are compatible with this cable?
  • It is compatible with Cisco Nexus, Catalyst, and ASR series switches and routers that support 40G QSFP+ ports.
    • Can this cable be used for stacking switches?
  • No, this cable is intended for data connectivity, not stacking. Cisco stacking cables are different.
    • What is the difference between a DAC and an optical transceiver?
  • A DAC (Direct Attach Copper) cable is a cost-effective, low-power alternative to optical transceivers but is limited to shorter distances.
