TIA Developing TSB for Shared Pathways, Shared Sheaths

Dec. 15, 2023
The TIA’s TR-42.7 Copper Cabling Systems Engineering Committee will update TSB-190, which addresses alien crosstalk and other technical issues.

The Telecommunications Industry Association (TIA) issued a call for interest for the development of Telecommunications Systems Bulletin TSB-190-A, a document that is initially titled “Guidelines on Shared Pathways and Shared Sheaths.” The document will be an update to the original TSB-190, which was most recently reaffirmed in 2018. The TIA is actively seeking participation in the revision process. The association said interested parties may include installers and end-users of cabling systems as well as members of the Institute of Electrical and Electronics Engineers (IEEE).

TSB-190-A will provide guidance and support data related to the following scenarios.

  • Multiple applications operating over different cable categories or constructions sharing the same pathways
  • Alien crosstalk interference between Category 6A UTP cables manufactured by different manufacturers
  • Alien crosstalk between Category 6A UTP cables and other category cables
  • Multiple applications running within the same sheath

Anyone interested in finding out more or participating in the revision process can reach Cheryl Thibideau at [email protected].
