Proposed Number of Services to Coexist in the Cable Bundle With VDSL2 Service
The authors propose a suitable number of different services to coexist in the same cable bundle with VDSL2 service (Very high bit-rate Digital Subscriber Line 2). The situation for quad cables and twisted pairs is considered for real-case and bad-case assumptions. NEXT (Near-End CRosstalk), FEXT (Far-End CRosstalk), and background AWGN (Additive White Gaussian Noise) were taken into consideration. The real-case assumption was proven to be a good choice for limiting the noise that may affect VDSL2 service, by determining the services and their numbers to be used in the same cable bundle.
