OPTICAL FIBER CABLE WITH RETAINING SHEATH

摘要

The invention concerns a telecommunication cable (1) of the micro-cable or mini-cable type comprising optical fibers (2) housed in a thin retaining sheath (3) including an outer layer (4) enclosing the retaining sheath (3). The outer layer has a friction coefficient lower than that of the retaining sheath and a higher stiffness than that of the retaining sheath. Said features reduce friction and increase the stiffness of the cable when the latter is laid by blowing or floating in a pipe.
