Internet infrastructure preferred fiber optic cablesused for a new purpose. According to a new study, it will be possible to choose optical cables for eavesdropping. The device, which can detect small changes in signals with cables, conversations It will detect more than a kilometer away. Here are the details!
Fiber optic cables to aid eavesdropping
Optical fiber networks, which are widely used all over the world, earthquake detection, underground structure exploration and urban traffic flow It is known for its applications such as monitoring. In addition, fiber optic networks have many positive effects on people’s lives and production.
in Beijing Tsinghua UniversityThe new study led by researchers at the University revealed the new purpose of fiber optic cables. In the article they published, they explain that fiber optic cables will also help to gain additional information.

Did James Webb catch a supernova? The space telescope spotted a bright object 3 to 4 billion light-years away.
Optical fiber data is used around the world to transport light beams across the oceans and underground. Researchers previously used to watch whales you ask found that it can be used as Now they will use it to eavesdrop. A type of broadband network architecture that uses optical fiber, fiber to facilities (FTTP) is located as.
As the name suggests, this is where the cables run all the way into the building, whether it’s a house, apartment or office. According to the new study, according to the current settlement mode of FTTP, there will be up to several meters of fiber installation into the homes of the residents. However, audio signals are transmitted by fiber without any additional equipment installed in the resident’s home. to the light wave will be modulated.
This will allow other people to eavesdrop on them and recover them in remote locations along the fiber link. from the Swiss Federal Institute of Technology Luc Thevenaz, About this subject, “Optical fibers are very sensitive to vibration.” said.
So, what do you think about this subject? Do you think it is possible to eavesdrop on fiber optic cables? You can share your views with us in the comments section.
