– Longer Loop Lengths, Higher Densities & Improved Manageability
Telecom equipment maker Nokia, which recently bought Alcatel Lucent, has made three major announcements about its G.fast gear. All are aimed at making it easier and faster for telcos to deploy G.fast gear, increasing the length of the copperwires from fiber to the residence, improving serviceability and increase the number of options telcos have for network architectures. The new products and services are:
– Micro nodes that allow for higher densities and longer loop lengths from cabinets and distribution points to the residence
– Programmability and automation to the copperwire network to accelerate G.fast deployments by 50%
– Software-defined networking and network function virtualization (SDN/NFV) to improve accessibility, serviceability and turn-up time
Nokia said telcos are increasingly turning to technologies like G.fast that uses portions of their existing copperwire networks to deliver fiber-like speeds to subscribers over short distances. However, to achieve these speeds, G.fast requires that micro-nodes be installed close to residence, which can be challenging for telcos to deploy, configure and manage on a large scale. Nokia said its new G.fast micro-nodes can cut roll-out times in half by providing flexible plug-and-play solutions that can scale in line with demand and that they allow for both distribution point and cabinet deployment models.
G.fast requires vectoring to perform at its best and Nokia said that it is the global leader in vectoring technology. Vectoring and the extension of loop lengths are, it said, key to enable cabinet-based deployments.
