Direct-attach cable for 50 Gbit/s links

This HPE DAC cable connects a QSFP56 port to an SFP56 port at 50 Gbit/s over a 0.65 m passive copper assembly. It is built for short-reach links between switches, servers or storage arrays inside the same rack. The fixed-length design removes the need for separate transceivers and patch cords.

Replaces separate optics and fibre for short runs

When the connection distance stays within 0.65 m this cable eliminates two transceivers and a fibre patch lead, cutting cost, power draw and insertion loss. The jump is worth it whenever the link budget and rack layout allow a fixed copper reach instead of pluggable optics.

Suits operators building dense 50 Gbit/s breakout

Network teams who need a QSFP56-to-SFP56 breakout for 50 Gbit/s server uplinks or switch interconnects will find the length and connector match convenient. Buyers who need longer reach, active optics or a different connector combination should look at other cable types.

Questions about this item

What is the exact length of the S1J07A cable in metres?

The cable is 0.65 m long, which is 2.13 ft or 2.3 ft depending on the specification source.

Which end connects to a 50 Gbit/s QSFP56 port and which to an SFP56 port?

The first end has a QSFP56 connector; the second end has an SFP56 connector, both rated for 50 Gbit/s.

Does the passive DAC require any firmware updates or module replacements over time?

As a passive direct-attach copper cable it has no active components, so no firmware or transceiver replacements are needed.
