Reliance Jio deploys multi-terabit converged packet-optical tech with 200 Gb/s speeds to support data explosion

Ciena bagged a big ticket contract from Reliance Jio, the country’s newest 4G service provider, to deploy multi-terabit converged packet-optical technology for the latter’s pan-India 4G network across the country. The deployment will help Reliance Jio “unleash the digital revolution in India,” according to an official statement.

Operating at speeds up to 200 Gb/s, this deployment gives Jio a high-speed, highly resilient mesh network with an unprecedented scale to support its surging subscriber base and subsequent data explosion. Jio is India’s newest mobile network operator, with a pan-India 4G network. Jio has set up the world’s largest greenfield all-IP, video-ready network. Jio commenced operations in September 2016 and has added more than 100 million subscribers in just 170 days. Jio is a wholly-owned subsidiary of Reliance Industries.

“With Ciena, we are not only able to provide robust scalability to offer new levels of data consumption, which is already 8 to 10 times above market levels, but also a supreme level of confidence in our network’s reliability and level of service that stands out in our marketplace. Ciena’s coherent technological offerings and proven control plane technology is helping to make us the fastest growing 4G network in the world,” Jyotindra Thacker, President at Reliance Jio.

Jio deployed Ciena’s 6500 and 5430 Packet-Optical Platforms, powered by WaveLogic coherent technology to provide ultra-high-bandwidth services across its entire network. This core network connects all major cities of India and is already carrying more than 85 percent of the total data traffic carried through Indian telecom networks, and the deployed network is ready for subscriber additions for months to come. This scale makes it one of the world’s largest multi-terabit networks.

With Ciena-enabled OneConnect restoration, unexpected fiber route failures are restored by autonomously choosing a divergent path that provides higher uptime and unmatched customer experience compared to traditional network architectures.

“In fast-growing markets like India, there’s a pent-up demand for more bandwidth not only for personal use but also to sustain business growth and development. Jio understands the necessity in today’s digital environment to provide high-bandwidth services anytime, anywhere. Ciena seeks to continue our momentum across these markets in developing long-lasting customer relationships to enrich the lives of residents in these areas,” Steve Alexander, Senior Vice President and Chief Technology Officer, Ciena.

If Jio can’t handle 100 million users with 1GB data per day how on the earth they will be able to handle 200 million users (since they are adding more users plus MNP) with 1GB and more data (top ups extra ) per day plans Data speeds at my place went from 8-10 Mbps from Sept 5 to 200kbps on LTE band 5. Where are extra towers if needed or network team or small cells etc Even in Delhi there data speeds are pathetic forget about other areas. What next they are going to do which they never bothered To… Read more »

Multiple SIM usage will be stopped to a large extent from April 1 & that’ll make a huge difference. Jio apps like Jio TV & Jio cinema usage will decline sharply too, that’ll release a lot of bandwidth as well.


All users (barring few Jio staffs) are currently on 1GB daily quota including Jio apps and hence no unlimited means they can use only 1GB then how it will increase speeds after 31st as all remaining users will continue to use it as they please Multiple sim usage are all Jio customer collectively 100 million . If multiple Sims stops Jio user base decreases which will increase speeds which begs a question was Jio network designed for 60-70 million users and they can get only 1GB daily ? Then How will they get 200 million customers and how will they… Read more »

A network needs hardware, software, as well as optimization. Jio has hardware, software, but no optimization. Their networks are not stable right now. They have partnered with Airhop or someone similar for SON or self optimizing networks. It will help improve the network in the cities where the congestion is the max. A lot of users are noticing improvements on Jio in congested cities. It will take a while for Jio to bring the improvements all over India. I hope they cover all India by September.


By September ? What happened to world class network, staff and all IP system ? Why can’t they do it before 31st March ? 8 months after launch and 7 years since launch they haven’t done it if they can’t why launch ? Why charge ? They are enrolling users without providing them 4G services speeds are way below 4G even not comparable to 3G Jio4GVoice is still buggy and they have spread lies on POI accept it you need VoLTE phones even then there is no guarantee of call drops Is this transparency ? accept it which is cheating… Read more »


For me the true test for jio speeds will happen next month once the free usage comes to an end. Not everyone would go for the 303 plan and there would be a massive drop in data consumption. If post that we see an improvement in Network and speed in Jio things would be good, But if it still continues to struggle then it will loose lot of customers from May on wards and folks may not continue with them, specially those who live in areas where there is a network and speed issues.
