- This optical fiber integrates optical cable and power cable to avoid secondary wiring and reduce the cost of construction and network building cost.
- The optical fiber has small outer diameter, light weight and small footprint. In general, a series of problems solved by multiple cables can be replaced by a single cable.
- This product has great bending performance and good side-pressure resistance performance and is easy to construct.
