MGTSV cable, or flame-retardant mine communication cable, is a fiber optic transmission cable designed for underground environments such as coal and gold mines. It is primarily used for signal transmission within mines, ensuring stable communication in complex environments such as those prone to flammable and explosive conditions, moisture, and mechanical impact. Its core feature is that it must pass the National Coal Mine Safety Mark Certification (MA/KA certification), making it a mandatory certification product. Products that have not obtained certification are not allowed to be used in mining scenarios.
