Bare Fiber/Tight Buffer Optical Cable Singlemode Multimode


Loose-tube 250um and tight-buffered 900um fiber cables actually start with the same 250um bare fibers that feature the same size fiber core (i.e., 62.5um/50um for multimode and 9um for singlemode), 125um cladding and soft 250um coating. The difference between these two cables all lies in the cable construction.

Tight-buffered 900um fiber includes an additional 900um layer of hard plastic over the 250um fibers for protection. Within the cable, several of these color-coded 900um tight buffered fibers are situated around a central strength member and then covered with Kevlar or aramid yarn for protection.
