"The Komi Republic is an area of ​​our increased attention.

In 2022-2023, according to the company, seven accidents were recorded on this section. Most of them were caused by human factors, not natural ones. The cable was damaged by third-party organizations carrying out uncoordinated excavation work in the security zone of the communication line. Not only Rostelecom subscribers suffered from this, but also other operators who do not have trunk resources. An additional backup channel, stretching from the village of Seregova through the city of Yemva and the village of Sindor to Ukhta, is designed to redistribute traffic in the event of such accidents.

There were many cable damages denmark whatsapp number database on the Syktyvkar-Ukhta section, and we built a backup communication line there, which runs parallel to the main one," Alexander Loginov, Vice President and Director of the North-West MRF of PJSC Rostelecom, told ComNews. "95% of cable damages are caused by people. Active construction of oil and gas pipelines is underway in Komi, and despite the fact that we inform partners about the location of the cable, people do not always pay close attention to this. Sometimes the line is damaged by an excavator bucket or other equipment, and the entire north of the Komi Republic is left without communication."

Although natural cable damage is a "privilege" of areas with complex terrain, such as the Caucasus, in Komi, where taiga and tundra predominate, it also happens.

"Once there was lightning damage. Lightning hit the cable, traveled along its metal armor for several hundred meters and melted the optics at the exit point. This is a unique case. There have been other natural damages. Where the cable is located near rivers, chunks of ice break off in the spring, dragging along the soil in which our cable is laid. But natural damages are isolated cases. The main reason is human activity, inattention, lack of coordination. Therefore, we systematically introduce redundancy," comments Alexander Loginov.

As the operator’s press service explained, work continues in the Komi Republic to build a backup line, geo-separated from the main data transmission channel.

Leading analyst of Mobile Research Group Eldar Murtazin told ComNews that duplication of the main channel is always done when possible.

"This is the key to success in telecom. If there are problems in any "optical ring", then the backup system ensures uninterrupted operation. In addition, duplication is important for expanding the channel's capacity. It must be justified by traffic. In some regions, such as Kunashir, it is too expensive to lay a duplicate cable, and this is not done," the analyst says.

Independent expert in the IT and telecom markets Vadim Plesskiy agrees with his colleague: "The construction of backup lines duplicating the main communication channels is standard practice for all trunk operators. However, in remote regions of the country with insufficiently well-developed infrastructure, backup channels may be absent."

The reasons for breakdowns and shutdowns of fiber optic lines depend on various factors, both natural and man-made, ComNews experts believe.
