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.
