- Industrial zone/mining area: Mandatory armor (resistant to mechanical impact)
- Data center computer room: Non-armored is preferred (to save bridge frame space)
- Coastal areas: 316L stainless steel armored (resistant to salt spray corrosion)
- Direct burial installation: Double-layer armoring (metal tape +PE sheath
- Overhead wiring: Central tube type armor (resistant to wind sway)
- Air-blowing construction: Micro-cable structure without armor (friction coefficient <0.15)
- Petrochemical plant: Armored optical cable (reducing the frequency of fault maintenance)
- Office buildings: Unarmored (TCO reduced by 27% within 5 years)
- National defense project: It is necessary to meet the armor requirements of GJB 1428B-2019
- Civil buildings: Comply with the GB/T 7424.2 standard
1.The typical value of the armor layer thickness is 0.15mm stainless steel tape (conforming to Telcordia GR-20)
2. The maximum traction force of unarmored OM4 optical cables in a 40G network should be ≤600N (according to EIA/TIA-568-D2)
3. The latest IEC 60794-1-2:2021 adds the anti-rolling test (cyclic loading of 500N/cm²)
