Fiber to the home (FTTH) architecture overview

Not all FTTH networks are built the same. Since construction and outside plant account for the majority of total network costs, getting the architecture right has a major impact on the business case.
 
The network architecture can also impact time-to-market, labor/training requirements, future upgradeability, network performance, and ultimately customer satisfaction. This paper provides an overview of two fundamental FTTH architecture categories—centralized and cascaded—that determines where in the network the fiber is split.

UK government commits £200 million to rural fibre broadband

UK chancellor of the exchequer, Philip Hammond, confirmed in the 2018 budget report that £200 million will be allocated to fund full fibre broadband connections in harder-to-reach and rural areas across the UK. This will allow for testing of new approaches to fibre rollout in rural areas, with the Borderlands, Cornwall, and Welsh valleys said to be amongst the first areas to benefit.

New CommScope long haul antenna product lines upgrade microwave antenna range

CommScope has upgraded its microwave antenna portfolio with the introduction of two new long-haul antenna product lines – USX and HX – into its Sentinel and ValuLine ranges. These are designed to ultimately replace the company’s existing long-haul antennas, providing next generation performance for cellular, broadcast, telecom and private networks.

OM4+: A case of the emperor's new clothes?

Over the last year, you may have heard proponents espouse the benefits of OM4+ multimode fibre. For instance, they claim it is better for single-wavelength applications, and it’s comparable to OM5 for multiwavelength application support. While OM4+ may have some useful attributes, which vary from company to company, that variation is a clue to the fact that in all cases it is proprietary, meaning it is not standardised. Essentially, the public is being asked to take OM4+ proponents at their word. As New York Yankees legend Yogi Berra once said, ‘It’s like déjà vu all over again’.

Cable companies consider coherent optics

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.

CommScope launches LazrSPEED 550 WideBand multimode fibre

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.
