Nokia Validates Coherent Optical Module Performance Using VIAVI ONT

Viavi Solutions Inc. today announced that Nokia has validated its coherent optical modules using the VIAVI ONT 800G FLEX DCO Module, which tests pluggable (CFP2) Digital Coherent Optics (DCO) modules. Nokia utilized this test capability as a beta customer, providing valuable feedback, and ultimately purchased the first ONT 800G FLEX DCO Module upon release. Communications service providers (CSPs) are striving to gain more efficiencies from their transport networks as they deploy faster technologies at the edge including 5G, Gigabit-to-the-Home and hyperscale. Coherent transport grows the traffic-carrying capacity for each wavelength that is deployed, regardless of the distance. This means increased overall network capacity with less hardware to deploy and manage, reduced energy consumption, and lower cost per bit transported. Pluggable coherent optics, a key component in coherent systems, play an increasingly important role for telecom operations, particularly in disaggregated ecosystems.
