The Addition of 28 AWG Patch Cords
ANSI/TIA-568.2-D will also bolster the utilization of 28 AWG patch cords in specific applications. Beforehand, the standard's position was that the cables shouldn't be utilized since they didn't meet requirements. Rather, the standard had suggested four balanced twisted-pair cables: 22 AWG to 26 AWG.
This is uplifting news for high-density applications where congestion, airflow, and sharp bend radius are significant contemplations. Their tight diameter permits these 28 AWG patch cords to be utilized in spots where 22 AWG to 26 AWG might be troublesome or difficult to use. li>
When it comes to utilizing 28 AWG patch cords with Power over Ethernet (PoE), the standard will likely incorporate an addendum sooner or later that maps out exceptions that should be made. For instance, the short response to: "Would I be able to utilize 28 AWG patch cords for PoE?" is "yes." But, there are a few impediments for applications that request more than 30W. To avoid any risk, Belden suggests keeping 28 AWG PoE patch cords in groups of 12 or less to limit temperature rise. li>
