Tata Communications announces TGN-IA2 subsea cable linking Singapore, Hong Kong, Japan to enhance connectivity
, on Tuesday, announced the
TGN-IA2 subsea cable
system to enhance connectivity for businesses across Asia. The cable connects Singapore, Hong Kong, and Japan and complements the existing TGN-IA cable system by offering interconnections to other regions.
The system is constructed by the
Asia Direct Cable
(ADC) consortium, of which, half-a-fibre pair is fully operated and managed by Tata Communications. This allows the company to independently manage capacity upgrades and make faster provisioning for customers.
The ADC is a global consortium of leading communications and technology companies, including NT (Thailand), China Telecom, China Unicom, PLDT Inc., Singtel, SoftBank Corp., Tata Communications and Viettel.
The multi-terabits capacity TGN-IA2 cable is expected to significantly enhance data transfer capabilities and offer diverse, scalable bandwidth solutions to hyperscalers, multinational corporations, and telecom operators.
Tata Communications operates multiple terabytes of capacities across its 500,000+ km round-the-globe subsea optical fibre network. This includes TGN-TIC, TGN-EA (Eurasia), TGN-Gulf, TGN-P (Pacific), TGN-A (Atlantic) and others.
Live Events
The Asia-Pacific region, particularly Southeast Asia, is now a global data transmission hub, with growing subsea investments from companies like Meta, Google, Amazon, and Microsoft. The region is witnessing a rapid build-out of
hyperscale data centres
, and
submarine cables
are critical to ensuring low-latency, high-throughput links between these facilities.
According to Telegeography, the global demand for international bandwidth is growing at over 30% annually, and Asia accounts for a significant share of this surge. Countries like India, Singapore, Indonesia, and the Philippines are now key landing points for such cables, facilitating
digital trade and cloud infrastructure
deployment.
India has recently seen large commitments in this space. For instance, Google is set to commission its Blue-Raman submarine cable system in Mumbai this year. Last month, Meta announced the 'Waterworth' project—the world's longest subsea cable connecting five continents with landings in India. Japan's NTT Data is also set to commission MIST - its first submarine cable system connecting Malaysia, India, Singapore and Thailand, entailing a total investment of $400 million.
Meanwhile, telecom operator
Bharti Airtel
has landed SEA-ME-WE-6 and 2Africa Pearls cables on Indian shores this year. Reliance Jio is also set to commission the India-Asia-Express (IAX) and India-Europe-Express (IEX) submarine cable systems, expanding the country's existing capacity significantly.

Troubles mount! One in six NRIs on H-1B visas feel threat of US deportation; many thinking of returning to India: Poll
Representative AI image H-1B visa trouble: A growing number of Indian professionals in the US on H-1B visas are facing an unexpected and alarming threat of deportation landing on their doorsteps before the official 60-day grace period even runs out. Laid off and staring down the barrel of a possible permanent US ban, many say it feels like a ticking time bomb. According to a poll of 1,584 verified professionals conducted on the anonymous workplace app Blind between August 6 and August 8, 2025, one in six (16%) said they or someone they know has received a Notice to Appear (NTA) within the grace period after being laid off. Under normal rules, H-1B workers have 60 days to find a new employer or change visa status after job loss. But since mid-2025, reports have emerged of NTAs being issued within as little as two weeks, labelling recipients 'out of status.' 'Multiple cases where NTAs were sent in 2 weeks.' a Meta user wrote on Blind. 'Immigration lawyers now advise leaving as soon as possible after [the] job ends otherwise you risk a permanent ban from the US,' the user added. This sudden escalation is forcing many to rethink long-term plans. Between July 28 and August 8, 2025, workplace community app Blind surveyed 2,089 verified Indian professionals in the US on work visas such as H-1B and L1, revealing deep concerns about job security and the future of US immigration. In the survey of 2,089 verified Indian professionals, 45% said they would return to India if forced to leave, 26% would move to another country, and 29% were unsure. What are NRIs biggest concerns about leaving US? When asked about their biggest concerns over leaving the US, respondents cited a significant pay cut (25%), lower quality of life (24%), cultural or family adjustment (13%), and fewer job opportunities (10%). Interestingly, 28% said they would have no concerns and would be open to leaving. On whether they would still opt for a US work visa if given the chance again, only 35% said 'yes.' While 27% were unsure and 38% said 'no,' pointing to a clear shift in how Indian professionals view the long-term value of immigrating to the US. What is driving this change? Real experiences are driving this change. More than one in three respondents (35%) said they or someone close to them had been forced to leave the US after losing a job while on a work visa, often under the looming threat of deportation during the brief grace period. The findings suggest a growing openness to leaving the US, with many indicating they would return to India if it came to that. Trump's recent call sparks sharp divide US President Donald Trump's recent call for US companies to 'stop hiring in India' has sparked a sharp divide in opinion. Among US-based professionals, 63% felt the move could benefit their companies, while 69% of India-based respondents believed it would hurt their firms. When asked if they or someone close to them had ever been forced to leave the US after being laid off, 10% said it happened to them directly, 25% said it happened to someone close, and 65% said no. The growing anxieties reflect a broader shift in the perception of the H-1B pathway, once seen as a golden ticket to American opportunities, now increasingly viewed as a high-risk gamble.

Bulk of Mercedes-Benz cars in India are E20 compliant: MD Santosh Iyer
A bulk of the Mercedes-Benz cars currently on Indian roads are E20 compliant, as the luxury carmaker has been selling such models in the country since 2018, its India Managing Director and Chief Executive Officer Santosh Iyer told Business Standard in an interview. E20 compliance means a vehicle's engine, fuel system, and emission-control components are designed and tested to operate safely on petrol blended with up to 20 per cent ethanol without causing damage or abnormal wear. In recent weeks, social media discussions have intensified over whether E20 fuel affects fuel efficiency and engine performance. 'Mercedes-Benz was the first in India to introduce a BS-6 compliant car. In August 2018, we introduced the new S-Class, which was BS-6 compliant… Mr Gadkari (Union road transport minister) himself flagged off that car,' Iyer said, adding that all BS-6 compliant cars sold in India have been E20 compliant as well. The German carmaker has not tested cars sold prior to August 2018 for the impact of E20 fuel on engines and fuel efficiency. Iyer admitted that these older models might face a slight impact on performance due to E20 fuel, which is now available at fuel pumps. 'We have sold close to 200,000 cars in India in the last 30 years. However, the last 100,000 units were sold in just the last six years. The last 150,000 units were sold in the last 10 years. So, a bulk of the cars we have sold in India would be E20 compliant,' he said. Iyer was speaking to reporters on Tuesday night after launching the Mercedes-AMG CLE 53 4MATIC+ Coupé — a high-performance, two-door luxury model — in India, with prices starting at ₹1.35 crore (ex-showroom, Delhi). 'Mercedes-Benz was one of the first luxury manufacturers to get E20 certification. We got it the moment we introduced BS-6 compliant cars. Later, in 2024, we started getting E20 certificates for our cars. So, in that sense, all our cars that we sell in India are fully compliant today,' he said. 'I think material compatibility (with E20 fuel) also remains for cars we sold earlier. But by the laws of physics and chemistry, you can say that with a lower or higher ethanol rating, the combustion process is different… I would say you will definitely have a difference in performance,' he said. 'But today, the cars we are currently selling have no change in performance because they are all compatible with E20 fuel,' he noted. 'The cars that were sold many years back might have a slight impact on performance, but the government's direction is clear, and from April 2024, we started getting our cars certified as E20 compliant.' Mercedes-Benz, India's top luxury carmaker, began FY26 with its best-ever April–June sales, delivering 4,238 cars — a 10 per cent increase from the previous year.

Bulk of Mercedes cars on road are E20 compliant, says MD
Bulk of Mercedes-Benz cars currently on Indian roads are E20-compliant and the luxury carmaker has been selling such models in the country since 2018, the firm's India Managing Director & CEO Santosh Iyer told Business Standard in an interview. E20 compliance means that a vehicle's engine, fuel system, and emission-control components are designed and tested to operate safely on petrol blended with up to 20 per cent ethanol without causing damage. There have, however, been heightened social media discussions during the past few weeks about whether E20 fuel affects efficiency and engine performance. 'Mercedes Benz was the first in India to introduce a BS-6 compliant car. In August 2018, we introduced the new S class, which was BS-6 Gadkari (Union roads minister) himself flagged that car,' Iyer said, adding that all BS-6 compliant cars sold in India have been E20 compliant, too.
