Tight Buffer Distribution Fiber optic Cables
◎ Applications
☆ Short and medium distance,indoor and protected environments.
☆ As a riser,plenum ,or general purpose cable.
☆ Interconnection of distribution boxes,of the distribution boxes and customer
equipment,and between floors.
◎ Installations
Installed along the wall、 the roof、 interlayer、canal indoor.
◎ Constructions:
The cable contains 4 to 72 fibers individually buffered to 0.9 mm in a tight
or semi tight construction and coded .The cable structure depends on the
number of fibers:
----
the 4 to 12 fiber cables contain individual fibers without sub-units.
----
in the16 to 72 fiber cables the fibers are grouped in the sub-units.
In the 4 to 12 fiber cables ,the individual fibers are stranded and protected
by aramid yarn and a PVC or halogen-free flame-retardant jacket.In the 16
to 72 fiber cables the fibers are grouped into sub-units which are laid helically along the cable axis.Each sub-units contains 4 to 6 fibers,aramid yarn and a PVC or halogen-free flame-retardant sheath .The 72-fiber cable consists of twelve sub-units,nine of them are stranded around a central elment made of 3 sub-units.

◎ Product Highlights
☆ Small diameter and light weight.
☆ The high tension characteristics of the aramid yarn serving as strength member can offer good stability in the transmission performance.
☆ Compact and flexible construction especially suitable for indoor installations .
☆ Tight Buffer fibers are made from fiber rods with good linearity and low extruding output.By careful calibration of the vacuum pumping equipment,the uniformity of the outer diameter of the tight buffer fibers can be easily achieve with excellent strippability.
☆ LSOH jackets can be offered for indoor application for which flame retardancy is required.
☆ Cutting edge production equipment,good quality materials and optimized process ensure low induced attenuation within the operating temperature range.
☆ Fiber Geometry are strictly monitored to ensure superior transmission performance.
