Dell E Dell Networking 200GbE QSFP28 DD Passive Direct Attach Cable No FEC 2 Meter Customer Kit
This is a Dell Networking 200GbE QSFP28-DD passive Direct Attach Copper (DAC) cable, 2 metres in length, configured with no FEC (Forward Error Correction). QSFP28-DD (Double Density) DAC cables are used to link switches and servers at very high speeds -- 200 gigabits per second in this case -- over short distances such as within or between adjacent racks, avoiding the cost of optical transceivers and fibre for connections that don't need to span a whole data hall. Being passive means the cable carries no active signal-conditioning electronics of its own, which keeps cost and power draw low but limits its practical reach to a few metres, matching this cable's 2-metre length. The 'No FEC' designation means the link relies on the connected switch ports' own native signal integrity rather than an additional forward-error-correction layer, a configuration choice made to match the specific switch platforms it's being deployed between. It ships as a Dell customer-installable kit.
