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
