Modern hybrid fibre coaxial (HFC) cable access networks are very different to their original home television delivery-focussed incarnation, observes Alberto Campos, distinguished technologist at CableLabs, in Louisville, Colorado. ‘Broadcast TV demand has been decreasing,’ he told Fibre Systems. ‘Online or on-demand viewing and broadband internet have been increasing and are the biggest residential items.’ Our appetite for data seems insatiable, with internet connection speeds accelerating at approximately 45 per cent annually, he says.
To meet the challenges associated with escalating data rates and the ongoing need for higher bandwidth in the data centre, CommScope has introduced SYSTIMAX cabling and connectivity products based on its LazrSPEED 550 WideBand multimode fibre (WBMMF).
CommScope demonstrated the capabilities of the new fibre alongside Finisar’s new short-wavelength division multiplexing (SWDM) transceivers at OFC 2015. The emerging WBMMF standard enables up to four times more bandwidth at longer distances than standard multimode fibre.
