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

Colouring of optical fiber is a procedure of placing colour coating for the surface of fiber. This process consists of a number of steps: pulling the fiber through the die (colour covering unit), coloring the fiber, then drying out the colour covering and winding the finished product to the spools for transport.

As color covering Ultra violet-curable color is utilized, which is dried by intensive UV radiation. The density of the coating can differ from 4 to 6 µ. The use of modern gear enables to get the colouring speed of 3000 m / min and ensures good quality items productivity.

For optical fiber coloring different graphs of colors are employed according to different nationwide and international standards. As well as the regular coloring procedure “Optic fiber Techniques” utilize the technologies of “ring marking”, which makes it possible to encode 36 optical fibers by different pitch coloring.

To balance the process of colour covering drying out nitrogen can be used in the UV obstruct. Netrogen replaces atmospheric o2 in tubes of UV lights, which can guarantee the higher-high quality drying out from the Ultra violet-curable coating.

Due to the utilization of higher-high quality materials and high-technology gear of the world’s leading producer Nextrom, the attenuation coefficient of the standard optical fiber continues to be virtually unchanged right after colouring.

The winding of optical fiber complies using the following requirements: proper choice of winding pitch, minimum mistakes of spool geometry and steady lightweight winding. Rigid conformity with the previously mentioned specifications facilitates the storage space of fiber and preserves the quality of winding during transport. This really helps to steer clear of issues in further processing of items and production of optical modules and cables.

Features of utilizing “Optic fiber Techniques” JSC coloured fiber:

• simplification of additional handling and differentiation;

• Simplification and acceleration of last product manufacturing;

• Improved safety towards moisture intake / hydrolysis;

• Lowering the costs and time of production actions related to the planning of materials and procedures of optical fiber coloring;

• Emphasis of the cable television business to the main exercise, without having distraction for maintenance intermediate / preparatory creation sites.

Specifications For Colour Codes

There is a colour code standard in TIA, TIA-598 that deals with cable air wiper, which most manufacturers embrace and guide, even though there are numerous exclusions based on consumer specifications or choices. Is what TIA-598 suggests:

Cable Coat Colours

Colored outer jackets or print out may be applied on Property Distribution Cable, Premises Interconnect Cable or Interconnect Power cord, or Premises Breakout Cable to identify the classification and fiber sizes in the fiber. (Outside wires are typically dark for protection against Ultra violet light and markings are printed around the cable.)

When coloured jackets are employed to identify the type of fiber in cable containing only one fiber type, the colours will probably be as pointed out in Table 3. Other colours may be used providing that the print around the external jacket identifies fiber categories. This kind of colors needs to be as decided upon among manufacturer and consumer.

Unless or else specific, the outer jacket of premises cable television that contains a lot more than one fiber kind will use a printed story to identify the quantities and types of fibers inside the cable television. Table 3 demonstrates the favorite nomenclature for that different fiber kinds, as an example “12 Fiber, 8 x 50/125, 4 x SM.” Some producers use black since the coat colour for crossbreed or composite cables.

When the print out in the external coat of property cable television is used to identify the types and classifications from the fiber, the nomenclature of Table 3 is favored for the different fiber kinds. Unique print out characters for other fiber kinds may be regarded as for accessory for Desk 3 at some future date.

NOTES:

1) Natural overcoats with coloured tracers may be used instead of solid-colour jackets.

2) Because of the restricted number of programs for these particular fibers, print out nomenclature have to be arranged between manufacturer and enduser

3) Other colors may be applied providing that the print out on the external

coat recognizes fiber classifications per subclause 4.3.3.

4) For a few Premises Cable television functional types (e.g., plenum wires), colored jacket materials may not really available. Unique jacket colors for other fiber kinds may be considered for addition to Desk 3 at some future date.

Users happen to be installing crossbreed (Millimeters SM) wires in the anchor for many years. With the property fiber optic cabling now such as several kinds of 50/125 fiber, 62.5/125 and singlemode fibers, handling the cable plant is much more challenging. We have now already seen cases of customers and installers being confused and obtaining terrible check outcomes, as well as having troubles with systems working when linked within the incorrect fiber kind. Connector color codes may be utilized to determine fiber kind also. If uncertain about the fiber, core dimension can be based on looking at the connector ferrule having a fiber optic inspection microscope while enlightening the fiber with a white light (flashlight).

Connector Colour Codes:

Because the very first times of Optical fiber coloring machine, orange, black or grey was multimode and yellow singlemode. However, the advent of metallic connectors like the FC and Saint made connector color coding difficult, so coloured stress relief footwear had been frequently utilized.

Within the cable or within each tube within a loose tube cable, person fibers will likely be colour coded for identification. Fibers follow the convention made for phone wires other than fibers are recognized separately, not in sets.

Barrier pipes stick to the exact same colour series as much as 12 pipes, then tubes 13-24 will repeat the colours with a black stripe (black will have a yellowish stripe), tubes 25-36 will follow exactly the same colour with the qmaydo stripe, 37-48 make use of a green stripe, following the same colour code series for your stripe. Pipes that contains more than 12 fibers uses binder tape to separate fibers into organizations. Ribbon wires stick to this color sequence also.

For splicing, like colour fibers are generally spliced to ensure continuity of colour codes throughout a cable operate.
