The mini OLT, which is currently available and sports the company’s Quillion chipset, is designed for street cabinet deployment in support of rural and fiber to the business part applications or in mobile network base stations.

Nokia has unveiled the Lightspan DF-16GM optical line terminal (OLT) for 25G PON requirements. The mini OLT, which is currently available and sports the company’s Quillion chipset, is designed for street cabinet deployment in support of rural and fiber to the business part applications or in mobile network base stations.

The Lightspan DF-16GM is the only mini OLT available that can support GPON, XGS-PON and 25G PON, Nokia asserts. The system also is the fastest in its class and requires half the energy of its predecessor and 25% less energy than prescribed by the EU Code of Conduct, Nokia adds.

“Fiber deployments are accelerating and extending to rural areas and new segments such as enterprise and mobile transport,” said Sandy Motley, president, Fixed Networks at Nokia. “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.”

“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,” commented Emir Halilovic, principal analyst at Global Data, via a Nokia press release. “10-Gbps-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.”
