SINGLE MODEG.652.D DIRECT BURIED OPTICAL FIBER CABLE
Steel tape armored optical fiber cables for direct burial are a popular outside-plant solution. Corrugated steel tape combined with a robust polyethylene outer jacket delivers rugged durability and improved rodent resistance. These cables are manufactured to international standards.
Applications
- Direct buried installation
- Data, video & voice transmission
- Rodent-resistant installations
Cable Construction (summary)
- Loose tube filled with gel, stranded around a central strength member
- Water-blocking materials (yarns / tapes)
- Polyethylene inner sheath + corrugated steel tape armor
- Robust polyethylene outer jacket
