“Optic fiber Techniques” announces the launch of optical fiber coloring line. For expanding the assortment of produced items, “Optic fiber Techniques” has launched secondary coating line in August 2018. Now there is a possibility for cable businesses to purchase coloured optical fiber.

Colouring of optical fiber is a procedure for placing colour covering to the surface area of fiber. The procedure contains several actions: tugging the fiber from the perish (color covering unit), coloring the fiber, then drying out the colour coating and winding the finished product to the spools for transportation.

As colour covering UV-curable color is used, that is certainly dried by intense Ultra violet rays. The thickness in the coating can change from 4 to 6 µ. The usage of contemporary gear enables to obtain the coloring velocity of 3000 m / minutes and guarantees excellent quality products output.

For optical fiber colouring different graphs of colors are employed depending on various nationwide and worldwide standards. Along with the standard coloring process “Optic fiber Techniques” make use of the technology of “ring marking”, which makes it possible to encode 36 optical fibers by different pitch coloring.

To stabilize the entire process of colour covering drying nitrogen is utilized within the Ultra violet obstruct. Netrogen swithces atmospheric o2 in tubes of UV lights, which can ensure that the higher-high quality drying out of the UV-curable covering.

Because of the use of higher-quality components and high-technology equipment in the world’s leading producer Nextrom, the attenuation coefficient from the standard optical fiber continues to be practically unaffected after colouring.

The winding of optical fiber is in accordance with the following requirements: correct selection of winding pitch, minimal errors of spool geometry and steady lightweight winding. Strict compliance with all the previously mentioned specifications facilitates the storage of fiber and maintains the quality of winding throughout transport. This also helps to steer clear of issues in additional processing of merchandise and manufacture of optical components and cables.

Benefits of using “Optic fiber Techniques” JSC coloured fiber:

• simplification of further handling and differentiation;

• Simplification and acceleration of final product manufacturing;

• Enhanced protection towards dampness intake / hydrolysis;

• Lowering the expenses and period of production actions linked to the planning of components and processes of optical fiber colouring;

• Focus of the cable television business to the primary activity, without having diversion for maintenance intermediate / preparatory production sites.

Standards For Color Codes

There is a color code standard in TIA, TIA-598 that deals with yarn binder, which most manufacturers embrace and guide, even though there are lots of exceptions according to customer specifications or preferences. Is what TIA-598 suggests:

Cable Coat Colors

Coloured external jackets and print out may be applied on Premises Syndication Cable television, Property Interconnect Cable or Interconnect Cord, or Premises Breakout Cable to recognize the category and fiber dimensions from the fiber. (Outdoor cables are typically dark for protection against UV light and markings are published on the cable television.)

When coloured jackets are utilized to identify the type of fiber in cable containing only one fiber type, the shades shall be as pointed out in Table 3. Other colors may be used providing the print out around the outer coat recognizes fiber categories. This kind of colours needs to be as arranged among manufacturer and consumer.

Unless of course or else specified, the outer jacket of premises cable that contains a lot more than one fiber type shall make use of a printed legend to recognize the quantities and kinds of fibers within the cable. Table 3 shows the preferred nomenclature for the different fiber kinds, as an example “12 Fiber, 8 by 50/125, 4 by SM.” Some producers use dark because the coat colour for hybrid or composite wires.

When the print out in the external jacket of premises cable television is utilized to recognize the types and classifications in the fiber, the nomenclature of Table 3 is preferred for that different fiber types. Unique print out characters for other fiber kinds may be regarded as for addition to Desk 3 at some future date.


1) All-natural overcoats with coloured tracers may be utilized rather than strong-color jackets.

2) Because of the limited number of applications for these fibers, print out nomenclature have to be agreed upon between producer and enduser

3) Other colors may be used offering that the print out around the external

jacket identifies fiber classifications per subclause 4.3.3.

4) For many Premises Cable practical types (e.g., plenum cables), colored coat materials may not be readily available. Distinctive coat colors for other fiber types may be regarded as for accessory for Table 3 at some long term date.

Customers happen to be installing hybrid (Millimeters SM) wires inside the anchor for many years. With the premises fiber optic cabling now including several types of 50/125 fiber, 62.5/125 and singlemode fibers, handling the cable television plant is more difficult. We have already observed instances of users and installers being puzzled and getting terrible test outcomes, as well as having issues with networks working when linked over the incorrect fiber type. Connector color rules may be used to identify fiber type also. If uncertain concerning the fiber, primary size can be determined by examining the connector ferrule using a fiber optic inspection microscope while enlightening the fiber having a white-colored light (flash light).

Connector Colour Codes:

Considering that the very first times of Fiber coloring machine, orange, dark or gray was multimode and yellowish singlemode. Nevertheless, the arrival of metallic connectors like the FC and Saint made connector color coding difficult, so colored strain comfort boots were frequently used.

Inside the cable or within every pipe inside a free tube cable television, person fibers will likely be color coded for identification. Fibers follow the convention made for phone wires other than fibers are recognized individually, not in pairs.

Barrier pipes stick to the exact same colour series as much as 12 pipes, then tubes 13-24 will replicate the colours with a black stripe (dark may have a yellow stripe), pipes 25-36 will follow exactly the same colour with an qmaydo stripe, 37-48 utilize a eco-friendly stripe, pursuing the same colour program code sequence for your stripe. Tubes that contains a lot more than 12 fibers will use binder tape to separate fibers into organizations. Ribbon cables stick to this colour sequence also.

For splicing, like color fibers are usually spliced to ensure continuity of colour codes within a cable run.
