More recent standards like the ones from IECA (Insulated Cable Engineers Association) use the term hybrid for cables with fiber and conductors. In these cases the optical fiber is usually contained in a small splice tray and space for coiled fiber is limited. Based upon the existing and expanded use of strippable tight buffers for a number of applications, specific tight buffer standards need to be developed to allow cable manufacturers to develop and test this family of cables to a common set of standards. Historically, loose-tube gel-filled cable has been used for outdoor long-haul routes. Differences between conventional and micro cables are. This is is a type of fiber optic cable in which the optical fibers are surrounded by a tight-fitting buffer material, such as a plastic coating, to protect them from external damage. In the tight buffer construction, instead of using the gel layer loose tube cable has, it uses a two-layer coating. Inside that tube lays the fibre optic cores, the fibre cores lay within a water repellent gel that serves as a barrier against the elements. Notice the following: Loose tube cables con also be found filled with a water-resistant gel that surrounds every fiber it contains. However, as we have mentioned above, with tight-buffered cable, the splicing is eliminated and the installation reliability is greatly improved.
Because they're sturdier than loose-tube cables, they're best suited for moderate-length LAN/WAN connections, long indoor runs, and even direct burial. Inside buildings, cables don't have to be so strong to protect the fibers, but they have to meet all fire code provisions. These cables require addition work when the fibers are to be terminated. With local area network (LAN) reaching out further into the campus environment, often linking multiple buildings within short spans, the cable market is seeing an increased demand for a fiber optic cable suitable for both indoor and outdoor applications. TIA 455A Fiber Optic Test Procedures. Many of the field installable connectors rely on the tight buffer to provide mechanical stress-free strain relief of the optical fiber in the ferrule. Presently, any of a number of different tools are in use to remove buffers. These include tool type, microscopic damage to the coating caused by the stripping action, temperature conditioning of the buffered fiber prior to testing, method of pushing or pulling the buffer off, and clean ability of the coated and bare fiber post stripping operation. Multi-strand TB fiber is more common in premise local area networks. Loose Tube Fiber Optic Cable. Some of the main ones include: - IEC 60793-2-10 – This international standard specifies the general requirements and test methods for optical fibers and cables, including tight-buffer cables. Do some research about the entire installation process if you are not familiar with it. By using our site, you acknowledge that you have read and understood our Cookie Policy & Privacy Policy. It covers the general requirements and test methods for optical fibers and cables, including loose tube fiber optic cables.
The purpose of buffer tubes in fiber optic cable is to provide mechanical and environmental protection for the optical fibers inside. Some manufacturers have introduced "flexible ribbons" that are not solid 12 fiber ribbons but are 12 fibers joined with periodic connections to the fibers next to it. The indoor environment is less hostile and not subject to the extremes seen outdoors. Optical fiber, usually made of glass, which, as we have mentioned is what the. Table 2 shows the proposed categories and tool types for a proposed test methodology. Any cable that includes any conductive metal must be properly grounded and bonded per the NEC for safety. These tubes are filled with a gel-like compound that protects the fibers from moisture or physical stresses that may be experienced by the overall cable.
"buffer" to make the 125/250 um fiber more resistant to handling and termination. Why can loose-tube and tight-buffered cables be used for outdoor, indoors applications, respectively? Most all start with standard fiber with a primary buffer coating (250 microns) and add: Look at the pictures below to see how each type of cable incorporates these components. Marine Grade Fibre takes a standard loose tube fibre cable and protects it with a steel tube and galvanised steel wires. In the United States, all premises cables must carry identification and flammability ratings per the NEC (National Electrical Code) paragraph 770. In a loose tube cable design, color-coded plastic buffer tubes house and protect optical fibers. This type of cable protects the fiber from stresses caused by the environment, namely moisture and temperature.
And consider future expansion needs. But this acrylate layer is bound tightly to the plastic fiber layer, so the core is never exposed (as it can be with gel-filled cables) when the cable is bent or compressed underwater. In other cases the lack of excess length control and mechanical robustness made this design limited in usefulness. Tight buffered cable construction uses 900μm buffered fiber surrounded by water-resistant, dielectric strength member, and protected by a flexible flame-retardant outer jacket (or a rugged polyurethane outer jacket), and provides superior environmental and mechanical protection.
