“Optic fiber Systems” announces the launch of optical fiber coloring line. For growing the variety of manufactured products, “Optic fiber Techniques” has launched Optical fiber coloring machine in August 2018. Presently there is a possibility for cable companies to purchase colored optical fiber.
Colouring of optical fiber is a procedure for placing colour coating for the surface of fiber. The process includes several actions: pulling the fiber with the perish (color covering device), colouring the fiber, then drying out the color coating and winding the completed product on the spools for transportation.
As color covering Ultra violet-curable paint can be used, that is dried out by intensive Ultra violet radiation. The thickness from the covering can differ from 4 to 6 µ. Using modern equipment allows to get the coloring speed of 3000 m / min and guarantees excellent quality products output.
For optical fiber coloring different charts of colors are used based on different national and worldwide specifications. In addition to the regular colouring procedure “Optic fiber Techniques” utilize the technology of “diamond ring marking”, which makes it possible to encode 36 optical fibers by various pitch colouring.
To balance the entire process of color covering drying out nitrogen can be used within the Ultra violet block. Netrogen swithces atmospheric oxygen in tubes of UV lamps, which can ensure the higher-quality drying out from the Ultra violet-curable coating.
Due to the usage of high-high quality components and-technology gear in the world’s leading producer Nextrom, the attenuation coefficient from the standard optical fiber remains practically unaffected after colouring.
The winding of optical fiber is in accordance with the subsequent specifications: proper collection of winding pitch, minimum errors of spool geometry and constant compact winding. Strict compliance with the above requirements facilitates the storage space of fiber and preserves the standard of winding during transport. This helps to steer clear of problems in additional handling of items and manufacture of optical components and cables.
Features of utilizing “Optic fiber Techniques” JSC colored fiber:
• simplification of further processing and differentiation;
• Simplification and acceleration of final product production;
• Improved protection towards dampness intake / hydrolysis;
• Decreasing the costs and duration of production actions related to the planning of components and processes of optical fiber colouring;
• Focus of the cable industry to the primary activity, without having diversion for maintenance intermediate / preparatory creation sites.
Specifications For Colour Codes
There is a color program code standard in TIA, TIA-598 that deals with cable air wiper, which most producers adopt and reference, although there are many exceptions according to consumer specifications or choices. The following is what TIA-598 recommends:
Cable television Coat Colors
Colored outer overcoats and/or print may be utilized on Property Distribution Cable, Property Interconnect Cable television or Interconnect Cord, or Property Breakout Cable television to distinguish the category and fiber sizes in the fiber. (Outside wires are generally dark for protection towards Ultra violet light and marks are printed in the cable television.)
When colored jackets are used to determine the type of fiber in cable containing only one fiber type, the colors shall be as pointed out in Table 3. Other colours may be applied providing the print out in the external jacket recognizes fiber classifications. Such colours ought to be as agreed upon between manufacturer and consumer.
Unless otherwise specified, the external jacket of property cable television that contains greater than one fiber type shall utilize a published legend to distinguish the quantities and types of fibers inside the cable. Desk 3 shows the preferred nomenclature for your different fiber kinds, as an example “12 Fiber, 8 by 50/125, 4 by SM.” Some manufacturers use black because the coat colour for crossbreed or composite cables.
If the print out on the external jacket of premises cable television is used to distinguish the types and classifications of the fiber, the nomenclature of Table 3 is favored for your various fiber kinds. Unique print out characters for other fiber types may be regarded as for addition to Table 3 at some long term date.
1) Natural overcoats with colored tracers may be applied as opposed to solid-color overcoats.
2) As a result of restricted number of applications for these particular fibers, print out nomenclature have to be arranged between manufacturer and enduser
3) Other colors may be applied offering the print out around the outer
coat recognizes fiber categories per subclause 4.3.3.
4) For some Property Cable television functional types (e.g., plenum cables), coloured jacket material may not be available. Distinctive coat colors for other fiber types may be looked at for addition to Table 3 at some future date.
Customers have already been setting up hybrid (MM SM) cables within the backbone for years. Using the premises fiber optic cabling now including several varieties of 50/125 fiber, 62.5/125 and singlemode fibers, managing the cable television plant is more challenging. We have now already seen instances of users and contractors being confused and getting bad test outcomes, as well as having troubles with systems operating when connected over the incorrect fiber type. Connector color rules may be utilized to determine fiber type also. If uncertain about the fiber, primary size can be based on examining the connector ferrule with a fiber optic inspection microscope whilst enlightening the fiber having a white-colored light (flashlight).
Connector Colour Rules:
Since the earliest events of Optical fiber coloring machine, orange, black or grey was multimode and yellowish singlemode. However, the arrival of metal connections like the FC and ST made connector colour programming difficult, so colored stress relief footwear had been often utilized.
Inside the cable or inside every pipe in a loose tube cable, individual fibers is going to be colour coded for identification. Fibers stick to the conference made for telephone cables except fibers are recognized separately, not in sets.
Barrier tubes adhere to the same colour series up to 12 pipes, then pipes 13-24 will repeat the colors with a black stripe (black may have a yellow stripe), tubes 25-36 follows exactly the same colour having an qmaydo stripe, 37-48 utilize a green stripe, following the same colour program code series for your stripe. Tubes containing greater than 12 fibers will make use of binder tape to separate fibers into groups. Ribbon wires follow this colour series also.
For splicing, like colour fibers are generally spliced to make certain continuity of colour codes throughout a cable television run.
