SFP+ Direct Attach Cables for EX Series Switches
Small form-factor pluggable plus transceiver (SFP+) direct attach copper cables, also
known as Twinax cables, are suitable for in-rack connections between servers and
switches. They are suitable for short distances up to 7 m, making them ideal for highly
cost-effective networking connectivity within a rack and between adjacent racks.
