Nokia has announced its smallest Optical Line Terminal (OLT) deployed with the Quillion chipset. The Lightspan DF-16GM OLT can simultaneously provide services from 1 to 25 Gb/s making it the fastest mini-OLT on the market. Designed for deployment in street cabinets and available today, the device is targeted at fiber network providers looking to extend their networks beyond dense urban environments.
The majority of fiber deployments have so far focused on high density, high volume urban areas where the business case is strongest. However, fiber network providers are now extending networks to business parks and rural areas with low density populations, as well as using them to connect small cells within their cellular networks.
The Lightspan DF-16GM addresses the market for these new use-cases which require high-capacity solutions in a small form-factor and that can be easily installed in distributed environments such as street cabinets and base stations.
Emir Halilovic, Principal Analyst at Global Data, said: “Cabinet-based OLTs give operators a lot more flexibility in network design and the demand for small size fiber solutions has increased significantly over the last few years. 10Gb/s plus capacity and low latency is needed to take advantage of new opportunities such as in the enterprise market, 5G transport, and edge cloud computing space. For instance, a CSP could run a line to a cabinet in an industrial park and then use the mini OLT to connect multiple SMEs on the park”
As the only mini OLT on the market to incorporate GPON, XGS-PON and 25G PON, the multipon Lightspan DF-16GM is fastest in its class and it also uses half the energy of its predecessor and 25% lower than prescribed by the EU Code of Conduct.
Sandy Motley, President, Fixed Networks at Nokia, said: “Fiber deployments are accelerating and extending to rural areas and new segments such as enterprise and mobile transport. We are thrilled to be able offer the Lightspan DF-16GM to operators who require high capacity, low density, small format fiber solutions which can be installed in street cabinets and enables them to address these new opportunities.”
