Many of us have likely experienced this in our daily lives: we often see small stone pillars along the roadside with the words "Military Cable" written on them. We all know that in cities, many fiber optic cables, like those in rural areas, are not connected by utility poles. Instead, for aesthetic reasons, these cables are buried underground. Military fiber optic cables, as the name suggests, are used by the military. So, what are the functions and characteristics of these small stone pillars?
What are the functions of defense cables?
1. Transmission equipment is the equipment that transmits optical and electrical signals from one location to another. This includes radio, wired, and fiber optic transmission equipment. Radio transmission equipment includes longwave, mediumwave, shortwave, ultrashortwave, microwaves, transceivers, and communication satellites. Wired transmission equipment includes overhead wires, overhead cables, underground cables, and submarine cables. Switching equipment connects callers to their intended users. This includes telephone exchanges and telegraph switches.
2. Types of defense communication networks include: telephone, telegraph, satellite, fiber-optic, and microwave relay networks, based on their service nature; and national (or long-distance), theater, urban, tactical, and mobile field networks, based on their service area.
3. In modern national defense development, all construction projects and military activities are inseparable from the exchange and transmission of information. Only with access to a wealth of information can all major decisions be made.
4. With the application of advanced technology in the military, military operations require extensive coordination, such as coordination between military services, coordination between the military and politics, diplomacy, the economy, and cultural propaganda, and coordination between the military and policy, all of which must be achieved through communications.
What are the characteristics of defense cables?
First, they offer extensive connections. Communications facilitate the connection between national defense and politics, the economy, various domestic social activities, and diplomacy. Internal defense activities are also facilitated through communications, and all internal defense activities are linked through communications.
Second, the communications industry does not produce physical products. Its product is the spatial transfer of information and mail items, and its production and consumption processes are essentially the same.
Third, defense communications must ensure the rapid, timely, accurate, and secure transmission of information to its destination. Military communications, in particular, are essential for operational command, ensuring the timely dissemination of superior orders and instructions, the timely reporting of subordinate information, and close coordination between friendly forces.
Defense cables, or the defense communications network, are interconnected systems composed of various communication lines and communication points serving national security. They generally consist of terminal equipment, transmission equipment, switching equipment, and their associated equipment. Terminal equipment is the communication equipment and its associated facilities installed at communication points. Some may wonder, since military cables are so blatantly labeled, aren't we afraid of sabotage by those with ulterior motives? In fact, there's no need to worry. Our national laws clearly stipulate that damaging public property is illegal.
