Outdoor Multi Loose Optic Fiber Cables
◎ Applications
Long Distance Outerside Telephone/CATV/Data Communications.
◎ Installations
Installed in Duct,Self Supporting(Figure 8 Self Supporting or ADSS
all Dielectric Self Supporting),Direct Burial(with Armouring).
◎ Constructions:
☆ The cable consists of 5 to 36 elements stranded in up to 3layers
around a central strength member and bound in a jacket.The elements
are usually fiber-containing tubes ,however fillers are also used ,when
needed,to preserve cable geometry .The cablecan be ordered with a
central member either made of a dielectric FRP ,or made of solid or
stranded steel coated with polyethylene.
☆ Two to twevel colored fibers are loosely laid in each tube that isfilled
with a water-blocking gel.Standard tube diameters are 2.1mm for up to
6 fibers per tube and 2.5mm for 8 to 12 fibers per tube.However ,other tube diameters and cable configurations are available.
☆ The total number of fibers ranges from 4 to 432 .A wide range of jacket options is avaiable : polyethylene,halogen-free flame-retardant material ,corrugated anti-rodent steel armorning ,fiberglass armorning ,aramid yarn,and more,A ripcord is located under esch jacket layer to facilitate jacket removal.

◎ Product Highlights
☆ Central Member,which is usually either made of a dielectric FRP,or made of solid or stranded steel coated with polyethylene.are placed at the centre of the cables. All the fiber containing tubes are placed in concentric layers around the central member and through the control of the twist length ,the fiber cable can achieve better pulling load and operating temperature.
☆ Tube Materials are water resistant and can sustain high tension.Being filled with special water blocking gel,the tube can provide water protection for the fibers inside the tube.
☆ Cables Interstices are also filled with water blocking gel to prsever cable geometry.
