Cable Specifications
EX Series switches support SFP+ passive direct attach cables. The passive Twinax cable
is a straight cable with no active electronic components. EX Series switches support 1 m,
3 m, 5 m, and 7 m long SFP+ passive direct attach cables.
Table 21 on page 47 describes the support for SFP+ passive direct attach cable lengths
on EX Series switches for Junos OS releases.
