Q&A

Q：We have a technical query regarding the DAC cable connecting HPE/Aruba JL255A x 2 units. It is possible that these units may be changed to an Edge-Core ECS4620-28P or a newer Edge-Core switch at a later stage.

We currently possess the standard 0.5m 10G SFP+ Passive DAC Twin Cable 30AWG. However, since it is the “Standard” variant, we are unsure if this cable would work with the HPE/Aruba JL255A. Could you please confirm if this cable is compatible with the HPE/Aruba JL255A?

A：We regret to inform you that the Standard cable will not work with the HPE/Aruba JL255A. You will need to purchase additional DAC specs for HPE or Aruba compatible products.

Q：Is there a Mellanox-compatible 100G QSFP28 to 4 x 25G SFP28 DAC breakout cable available? Could you please provide the specific model of Mellanox equipment?

A：We need this information to make an informed decision.

Q：What is the difference between a DAC Cable and optical fiber?

A：The main difference lies in the transmission method and applicable scenarios. A DAC Cable uses copper wires for data transmission, while optical fiber uses light signals for transmission. Optical fiber is usually suitable for long-distance high-speed transmission, while a DAC Cable is suitable for short-distance connections, typically within 10 meters. Fiber optic transmission has lower latency and higher bandwidth but is relatively more expensive, while a DAC Cable is more affordable.
