Nokia has introduced 10Gbps passive optical network (PON) and point-to-point (P2P) fiber to its mobile transport solution, enabling operators to leverage existing passive optical networks used in Fiber-to-the-home (FTTH) deployments and quickly gain the capacity and coverage 5G requires.
Nokia's mobile transport solution includes a number of new enhancements to its 7360 ISAM FX access node and 7368 ISAM ONT optical network termination devices, delivering the multi-gigabit capacity needed to support the massive throughput requirements and cell densification 5G requires.
Nokia said the ISAM portfolio combines carrier-grade transport capabilities with best-in-class synchronization support required in 3G, 4G and 5G mobile transport networks, providing operators such as Du and Telefonica with access to the flexibility needed to effectively ready their networks for 5G.
The enhanced mobile transport solution is also being used as part of a Bell Labs PoC that demonstrates the flexibility of 10G symmetrical PON networks for low latency applications such as mobile fronthaul. By adding gateway functionality to a next-generation PON network, Nokia is able to convert mobile fronthaul CPRI signals to Ethernet. The proof of concept validates the readiness of PON for fronthaul and its Ethernet-based evolutions for the 5G era.

Our solution allows operators to access existing PON networks that have virtually unlimited capacity to meet their needs today, with the added flexibility to add 10G PON evolutions gradually as demand for more bandwidth and services increases. The massive throughput and cell densification strategy of 5G make it a perfect match for existing FTTH deployments.

Fiber networks and next-generation access technologies such as XGS and TWDM-PON are uniquely positioned to address the evolving mobile transport needs in the era of 5G. By leveraging FTTH networks that are already in place, and vendor technologies such as Nokia's mobile transport solution, mobile operators can quickly gain access to the capacity, scale and flexibility needed to support 'anyhaul' applications.
