In a bid to unravel the mysteries hidden within the depths of the Moon, scientists are devising a groundbreaking plan to deploy fibre optic cables on its surface. Seismologists are vying to kick off this plan as they are driven by the enigma of lunar quakes and want to delve deeper into the moon's seismic activities.

A recent study by a team of researchers threw light on the challenges looming over this ambitious endeavour.

Utilising artificial seismograms generated from data retrieved by seismometers stationed during the Apollo missions, the team gauged the feasibility of such a network.

While the Apollo-era seismometers revealed seismic activities on the Moon's near side, the silence prevailing on the far side perplexed scientists. The quest to comprehend this disparity has propelled the necessity for additional seismometers.

With the Artemis mission gaining momentum, astronomers are poised to unlock the Moon's secrets. The proposed Distributed Acoustic Sensing (DAS) network, comprising detectors and sensors, holds promise in revolutionising lunar exploration.

However, lunar seismology confronts an obstacle - regolith. Regolith is the layer of loose, heterogeneous, unconsolidated rock and mineral fragments that covers the solid rock beneath the surface of a planet or moon.

Regolith can vary in composition and depth depending on factors such as geological processes, erosion, and meteorite impacts.

Notably, Regolith can hinder the detection of seismic waves crucial for unraveling lunar depths.&nbsp;

To surmount this challenge, scientists leverage advanced signal processing techniques. Array stacking, coupled with data from DAS sensors, has emerged as an important strategy in isolating desired signals from seismic noise.

But there is a necessity for meticulous preparations, including numerical simulations of wave propagation, before launching such a network.&nbsp;“Before a launch, there must be robust numerical simulations of wave propagation. We do the homework to find out if we can get the data, and what kinds of things we can do with the data," a researcher Wu reportedly said.

According to the expert, in case the researchers can explore and find out methods to supply power and repairs to the moon's potential seismic network, the array will be able to remain operational for many years.&nbsp;

Here's why scientists want fibre optic cables on moon

The Directorate General of Trade Remedies (DGTR), an arm of the Commerce Ministry of India, has imposed an anti-dumping duty on optical fibers from China, Korea and Indonesia in a move to secure the domestic industry from artificially cheap rates that are capturing the market.

The gazette notification issued on August 3 also mentioned that the imports were adding "injury to the domestic markets."&nbsp;

"The anti-dumping duty imposed under this notification shall be effective for a period of five years (unless revoked, superseded or amended earlier) from the date of publication,"&nbsp;the notification said.

The Times of India reported in July that the Commerce Ministry's recommendation to impose an anti-dumping duty comes at a time when India is undergoing a digitisation drive under the ambitious Bharat Net rural outreach plan, with commercial operators adding optical fibre to their networks to support 4G and 5G services.

The anti-dumping duty is likely to be a major relief to both domestic businesses and international companies that manufacture locally. Sterlite Industries, Birla Cable, Birla Furukawa Fibre Optics, HFCL, and American Corning are among the big names in the optical fibre business.

As per media reports, local manufacturers have been complaining that cheap imports, particularly from China, are hurting their business.

Upon an investigation by the DGTR, it was revealed that dumping did have a significant impact on Indian manufacturers. "It was further found that the growth in demand was almost entirely subsumed by such dumped imports," the Times of India quoted the agency as saying.

Scientists in Japan have developed an optical fibre with four cores to record the world's fastest internet speed.

Approximately 7.6 million times faster than the average internet speed&nbsp;in the houses of the United States, the engineers were able to achieve a record-breaking speed of 319 terabits.

At this speed, almost 80,000 movies can be downloaded in just one second. Whereas, in the US, the average internet speed is 42mbps.

The experiment has been conducted by Japan's National Institute of Information and Communications Technology.

After combining the four optical fibre cables, the engineers passed fires pulses of varying amplifications and wavelengths to transmit it to a greater distance.

Researchers hope that such fibers can ''enable practical high data-rate transmission in the near-term, contributing to the realization of the backbone communications system, necessary for the spread of new communication services beyond 5G.''

Countries and companies are seeking to protect or exploit deep-sea resources, from exploring for oil and gas to installing wind farms or laying fibre-optic cables for the internet.

Russia is laying its first undersea fibre optic communications cable through the Arctic as part of a state-run project to bring high-speed internet to its remote hydrocarbon-rich north after a private-led initiative stalled.

It aims to improve patchy communications and infrastructure in its far north where it has expanded its military presence and is developing the Northern Sea Route to become a major shipping lane.
