Production Modular Cord Next Loss Test Method and Requirements For Unshielded Twisted Pair Cabling


TIA/EIA-568-B.2 and TIA/EIA-568-B.2-1 defines a generic and non-destructive methodology for NEXT loss testing of modular plug cords respectively. The methodology described in the Standard contains the detailed NEXT loss calculations (which are based upon patch cable NEXT loss, test head NEXT loss, and cable and connector attenuation contributions) for the determination of the NEXT loss limits for any category 5e (TIA/EIA-588-B.2) or category 6 (TIA/EIA-568-B.2-1) patch cord and suitably designed test head.
