In this edition of Telecom Engine’s Audiocast series, David Thompson, product marketing director for ZyXEL, talks about how about new technologies are enhancing the viability of copper in the telco’s last mile network.
Thompson addresses the following questions in this Audiocast:
• While the telecom industry is in agreement that FTTH may be the ultimate future, the near-term reality is that the largest service providers are typically deploying some kind of hybrid FTTN architecture in Brownfield areas and installing FTTH in Greenfield markets. Are you finding that to be the case with your customer base?
• To assist the service provider's ability to extend the rate and reach of copper, copper bonding seems to one method to extend higher speed services to customers. How important is bonding to extending the life of existing copper?
• While ADSL2+ has made continued progress with all of the major DSL operators, large carriers such as Chungwa Telecom are making continued progress on the VDSL2 front. What is the current state of VDSL2 and overall customer deployments?
• Looking beyond VDSL2, there has been a lot of talk about Ericsson's ability to reach 500 Mbps on existing copper via vectored DSL. Although it is early in the game, what kinds of benefits could vectoring and other techniques at DSM bring to the table?
• Outside of providing residential broadband services, copper has become in recent years a viable option to fill in what Vertical Systems Group calls the speed and fiber gap for Ethernet services. Are you seeing similar opportunities to leverage Ethernet over Copper to extend to remote sites and SMBs that lack the capital to pay for multiple T1s?
