Multicom Fiber Optic Armored Cable - MARMLTxxxSM5. PACKING AND DRUM5.1 MULTICOM cables are coiled on bakelite, wooden or ironwood drum. During transportation, righttools should be used to avoid damaging the package and to handle with ease. Cables should beprotected from moisture; kept away from high temperature and fire sparks; protected from overbending and crushing; protected from mechanical stress and damage.Wooden strip sealWooden flangeInner tubCable fixing pointAxle holeCable trough5.2 The color of cable marking is white. (The printing shall be carried out at interval of 1 meter on theouter sheath of cable) The inner end of cable is then sealed with heat shrinkable end cap to preventingress of water and is made available for testing. The outer end of cable is equipped with heatshrinkable end cap. Outer sheath marking legend can be changed according to user’s requests.5.3 Outdoor cable packingBakelite, wooden or ironwood drumStrong wooden batten protection
