FAQs

Q: What type of cable is the R0Z26A?
A: It is a passive direct attach copper (DAC) cable with QSFP28 connectors on both ends, supporting 100GBASE-CR at 100 Gbps over a 5 metre length.

Q: Where would I use a 5m DAC rather than an optical transceiver?
A: A DAC suits short-range links such as cross-rack connections within a data centre. It is a lower-cost, low-power alternative to a pair of optical transceivers with fibre.

Q: Which devices is this cable compatible with?
A: It is intended for HPE Aruba Networking devices with QSFP28 ports, and can also link switches, routers and servers that offer QSFP28 interfaces.

Q: Can this cable be used to split a port into four 25G connections?
A: No. This is a straight QSFP28 to QSFP28 cable for a single 100G link. Splitting a port into four 25G connections requires a separate breakout cable and a port that supports it.

Q: Is this an active or passive cable?
A: It is a passive copper DAC, so it has no active optical or electronic conversion in the cable, which helps keep power draw and latency low.
