FTTA Fiber Handling Recommendations

Bend Radius When installing fiber cables, tower hands should pay attention to the minimum bend radius of the fiber. Standard fiber (complies with ITU-T recommendation G.652D) can maintain a minimum bend radius of five to 15 times the fiber cable diameter. Functionally, this corresponds to about three centimeters, or about one inch. Failure to observe […]

Cabling Architectures – FTTA Fundamentals 1

While a number of different system designs have been deployed, FTTA cabling architectures generally consist of a smaller base band unit (BBU) at the bottom of the tower and multiple fiber-fed remote radio units (RRUs) at the top of the tower. Fiber cables replace coaxial feeders running up the tower in order to support advanced technologies such […]
