Features
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. Standards
