TIA developing bulletin to address noise caused by flexing cables

TSB-5008 will discuss the characterization, detection and mitigation of flex-induced impulse noise.

The Telecommunications Industry Association’s (TIA) TR-42.7 Engineering Committee on Telecommunications Copper Cabling Systems recently issued a call for interest as part of its work to develop a Telecommunications Systems Bulletin (TSB) that will address cable impulse noise. TSB-5008 has the working title “Internally Generated Cable Impulse Noise Characterization, Detection and Mitigation.” TR-42.7 is developing the document, TIA explains, “because application developers have noted that certain cabling systems exhibit internally generated impulse noise when flexed.”

The TIA further explained that TSB-5008 “will describe the impulse events associated with flexing cables; will include example test results showing the pulse amplitudes, bandwidth, variability and time delay of the observed behavior; and will describe testing methodologies to characterize the impulse noise of a cabling system. These are provided together with guidance to end users to avoid potential transient bit errors due to this effect.”

By issuing the call for interest, TR-42.7 is actively seeking participating in the TSB’s development. The association noted, “The stakeholders may include, but not be limited to: cable manufacturers, IT professionals, datacom equipment designers, datacom equipment manufacturers.”

Anyone interested in participating in this or any other standard-development activities of TR-42 can get more information by emailing Germaine Palangdao at standards@tiaonline.org.
