What is a defense optical cable and what are the precautions? Yitong Optical Cable tells you that national defense optical cable is an optical cable used for military information transmission.
Generally, it is an optical cable line used for communication, information transmission and reception required for military needs such as military command communication and coordination between departments.
Different from civilian optical cables, they are definitely protected.
If the laying of national defense optical cables is prompted, then the nearby construction must undergo strict approval, and in most cases it is prohibited.
Once the crime of destruction, theft, or even theft of information is increased by one level compared with the crime of destroying civilian facilities.
Defense optical cables are generally buried at a depth of about 1.2-1.5 meters.
The original ground above the optical cable is then leveled and compacted under supervision, and then a 3m long, 6m wide and 20cm thick cover plate is poured on it with C30 concrete (the cover plate is equipped with Φ12 steel mesh, with a spacing of 20cm ), after the concrete strength reaches the design strength, backfill 50cm thick gravel soil on the cover plate.
Yitong Optical Cable tells you the precautions for the protection of national defense optical cables: 1 , It is strictly prohibited to build houses and sheds within 1 meter on both sides of optical cable communication lines. It is strictly prohibited to dig sand and soil, dig trenches and build canals, and set up toilets, cesspools, livestock pens, biogas pools, etc. within 3 meters.2. It is strictly prohibited to plant trees, bamboos, etc. within 2 meters on both sides of optical cable communication lines (0.75 meters on both sides of optical cable lines in urban areas).
3. It is strictly prohibited to carry out blasting within 20 meters of optical cable communication lines and carry out engineering survey and construction within 50 meters.
4. It is strictly prohibited to stack explosive and flammable products or set up a warehouse for explosive and flammable products next to optical cable communication lines.
5. It is strictly prohibited to dig sand and pile rocks in seasonal rivers and quicksand rivers, within 100 meters upstream and 150 meters downstream of optical cable communication lines.
