Direct Attached Cables (DACs)

25.11.2020

Siemon PVC jacketed Direct Attached Cables (DACs) are being discontinued and replaced with a dual rated LS0H/CM jacket for all global applications, eliminating the need for separate cable types. LSOH cable jacketing is a typical requirement for Europe, Africa, Middle East, Latin America and Asia. CM is a UL fire resistance rating defined by the NEC for general-purpose communications use. These assemblies are not suitable for use in risers or plenum environments.

CONSIDERATIONS

  • The changeover will occur for each DAC part number as the existing PVC stock is depleted.
  • New part numbers for the LS0H/CM DACs end with the suffix “L”.
  • There are no differences in performance or appearance except the cable legend.
  • Siemon electrical performance test reports are available upon request.
  • Please contact your Siemon salesperson if qualification samples are required.
