Hitachi's SingleUnit fiber optic cables utilize buffered fiber designs for pulling and installation robustness. Contractors specializing in field connectorization favor these cables for two reasons. Bright, individual colors on the buffered fibers help with identification, while the overall jacket diameter is kept as small as possible to facilitate installations around multiple bends, turns and corners. The aramid fiber strength member provides plenty of installation strength for multi-floor pulls. This time-tested design has been around for years and is a sure bet for fault-free service life.
