Networking firm Ciena is deepening its presence in India, working more closely with local telecom operators and big data centre players as Al demand rises. Ciena says India's data centre capacity may soon outgrow networks built for mobile traffic, so entirely new networks will be needed. Around $70-100 billion is already in the pipeline, with a similar sum promised for later. The company also says it is the first to launch optical networking gear capable of 1.6 Tbps, and it wants fibre to be easier to deploy.
