SDD has announced the availability of Cisco's Long-Reach Ethernet (LRE), an innovative broadband access and service delivery technology for scalable deployment of high speed Ethernet services on existing voice grade copper plants.
"LRE technology enables the simultaneous delivery of voice, video and data services at 5-15Mbps over existing telephone wire at distances up to 1372m (5000ft)," says Quintus Theron, Cisco product manager at SDD. Theron describes how LRE allows customers to utilise the benefits of Ethernet in places where they previously could not due to distance limitations or older wiring infrastructures such as those found in multi-unit buildings (MxUs) such as apartment and office buildings and enterprise environments which include education, healthcare and industrial campuses.
There has long been a question over the distance capabilities of Ethernet, which can now be properly resolved. In addition, LRE provides the performance, simplicity and ease-of-deployment associated with Ethernet. As a result, LRE is an access solution that enables enterprises, building operators and service providers to deploy high speed data services.
"LRE eliminates the need for costly infrastructure upgrades by enabling high speed access using existing telephone wire, which makes it a simple and economically viable option," states Theron.
Cisco's LRE can deliver broadband service on the same wire pair as Telkom regulated telephone service, digital telephone traffic and ISDN. In addition, Cisco LRE is compatible with asymmetric digital subscriber line (ADSL), allowing service providers to offer LRE to buildings where broadband services already exist. Theron then explains how these features dramatically reduce the capital and deployment costs for service providers and system integrators, creating a low cost, easy to deploy solution.
"LRE technology delivers the performance required to support simultaneous voice, video and data services, high speed Internet access, video-on-demand and IP telephony over distances of up to 5000ft, affording new revenue opportunities to service providers and MxU owners," concludes Theron.
SDD is a fully operational Cisco Solutions Provider.
