Splicing which creates a permanent joint between two fibers. In other cases the lack of excess length control and mechanical robustness made this design limited in usefulness. In a loose tube cable design, color-coded plastic buffer tubes house and protect optical fibers. Construction of 250um Loose-Tube and 900um Tight Buffered Fiber. It covers both loose-tube and tight-buffer cables. Tight-buffered cable designs typically offer a smaller package and more flexible cable. Since most loose tube cables have 12 fibers per tube, colors are specified for fibers 1-12, then tubes are color coded in the same manner, up to 144 fiber cables. Built for Tough Environments: Indoor/outdoor constructions feature materials that resist UV and moisture exposure. Fiber optic "cable" refers to the complete assembly of fibers, other internal parts like buffer tubes, ripcords, stiffeners, strength members all included inside an outer protective covering called the jacket. When mixing epoxy type terminations and field splice terminations one of the concerns is that using a loose tight buffer in an Epoxy connector can cause wicking of the epoxy back into the cable end many centimeters which will likely cause a fiber break near the connector backshell.

Loose tube fibre is most often used in external environments. In loose tube cables, the coated fiber "floats" within a rugged, abrasion resistant, oversized tube which is filled with optical gel. Due to its 250μm fibre core, unlike tight buffered fibre cables' size of 900μm, loose tube cable is often more cost effective and practical to deploy in outdoor applications. As you can see in the following image, a 250um bare fiber or 250um loose tube fiber contains a fiber core, 125um cladding and 250um coating (soft plastic), which are often surrounded by gel and contained within a central tube or multiple of tubes around a central strength member. They are mostly used in indoor, short-distance, and low-stress applications.

One to 12 fibers are placed in individual, water-blocked buffer tubes to isolate them from external forces and are typically stranded around a fiberglass central strength member to provide additional strength and resistance. Besides, the splices inside buildings may be held in a cabinet that is open to the air and may be located in a basement near a building entrance or in an electrical closet, both of which are uncontrolled environments, which leads to the splices being the item with the greatest failure rate in the cable system.

Tight buffer cables now needed to have a removable buffer layer in order to be compatible with such termination systems. You can crimp connectors directly to each fiber.

As the optical fiber and cable industry unfolded, several terms were coined to describe specific properties that were new and different from conventional wire processing. If you fear the CST might not cut it, then it's bigger brother indeed shall. The fiber counts of loose-tube 250um fiber cable range from 6 to 144, and besides the 6-fiber cable, the fibers are also grouped into sets of 12 for maximum density. Also, there are many types of mechanical splices that can be used to make either a permanent or temporary connection (such as for testing), and in many cases, fiber is pigtailed into a furcation tube to separate and protect it after being separated from a common jacket such as in indoor distribution cable.
