“Optic fiber Systems” announces the launch of optical fiber coloring line. For growing the variety of manufactured products, “Optic fiber Systems” has launched secondary coating line in August 2018. Now there is a possibility for cable companies to get colored optical fiber.
Colouring of optical fiber is a procedure of putting colour coating towards the surface of fiber. This process consists of a number of steps: tugging the fiber through the perish (color coating unit), coloring the fiber, then drying the color covering and winding the completed item onto the spools for transportation.
As colour covering Ultra violet-curable paint can be used, that is dried by intensive UV rays. The density in the covering can vary from 4 to 6 µ. The use of modern equipment enables to obtain the coloring speed of 3000 m / minutes and ensures superior quality products productivity.
For optical fiber coloring various charts of colors are utilized depending on various national and international specifications. In addition to the standard coloring process “Optic fiber Systems” utilize the technology of “diamond ring marking”, which makes it possible to encode 36 optical fibers by different pitch coloring.
To stabilize the process of color covering drying nitrogen is used in the Ultra violet block. Netrogen replaces atmospheric o2 in tubes of Ultra violet lamps, which can ensure that the higher-quality drying out in the UV-curable covering.
Because of the usage of high-high quality materials and-technology equipment of the world’s leading manufacturer Nextrom, the attenuation coefficient in the standard optical fiber remains practically unaffected after coloring.
The winding of optical fiber is in accordance with all the subsequent requirements: correct choice of winding pitch, minimal mistakes of spool geometry and constant lightweight winding. Strict conformity with the above requirements facilitates the storage of fiber and preserves the standard of winding throughout transport. This too helps to avoid problems in additional handling of merchandise and production of optical modules and cables.
Benefits of utilizing “Optic fiber Techniques” JSC colored fiber:
• simplification of further handling and differentiation;
• Simplification and acceleration of last item production;
• Enhanced safety towards dampness absorption / hydrolysis;
• Decreasing the costs and period of production actions linked to the planning of components and procedures of optical fiber coloring;
• Emphasis of the cable industry towards the main exercise, without distraction for maintenance intermediate / preparatory creation sites.
Specifications For Color Rules
There is a color code regular in TIA, TIA-598 that addresses TCC laser printer for cable, which most producers adopt and guide, even though there are numerous exceptions based on consumer specifications or preferences. The following is what TIA-598 recommends:
Cable television Jacket Colors
Coloured outer overcoats and print may be used on Premises Syndication Cable, Property Interconnect Cable television or Interconnect Power cord, or Premises Breakout Cable to recognize the category and fiber dimensions in the fiber. (Outdoor cables are usually black for protection against Ultra violet light and marks are published on the cable.)
When colored jackets are employed to determine the type of fiber in cable television that contains only one fiber kind, the colours will probably be as pointed out in Desk 3. Other colours may be utilized providing that this print in the external coat identifies fiber categories. This kind of colours should be as arranged among producer and consumer.
Unless of course or else specific, the outer coat of premises cable that contains more than one fiber kind shall use a published legend to distinguish the quantities and types of fibers inside the cable. Table 3 demonstrates the most preferred nomenclature for your different fiber kinds, for example “12 Fiber, 8 x 50/125, 4 by SM.” Some producers use dark as the coat colour for hybrid or composite wires.
Once the print out on the outer coat of premises cable television can be used to distinguish the kinds and categories of the fiber, the nomenclature of Table 3 is preferred for your different fiber types. Unique print figures for other fiber kinds may be regarded as for accessory for Table 3 at some future date.
1) All-natural overcoats with coloured tracers may be applied as opposed to solid-color overcoats.
2) Due to the limited number of programs for these fibers, print nomenclature should be arranged among producer and enduser
3) Other colors may be used providing that this print on the outer
coat recognizes fiber classifications for each subclause 4.3.3.
4) For some Property Cable functional kinds (e.g., plenum wires), coloured coat material may not available. Distinctive coat colors for other fiber types may be considered for accessory for Table 3 at some future date.
Users have already been installing crossbreed (MM SM) cables inside the backbone for many years. Using the property fiber optic wiring now such as a number of kinds of 50/125 fiber, 62.5/125 and singlemode fibers, handling the cable television herb is a lot more difficult. We have now already seen instances of users and installers becoming confused and getting bad test results, as well as having issues with networks operating when linked on the incorrect fiber type. Connector color codes may be employed to determine fiber type also. If uncertain regarding the fiber, core size can be dependant on looking at the connector ferrule with a fiber optic assessment microscope while illuminating the fiber using a white light (flash light).
Connector Color Codes:
Considering that the earliest times of Fiber coloring machine, orange, black or gray was multimode and yellowish singlemode. Nevertheless, the arrival of metallic connectors like the FC and ST created connector colour programming challenging, so colored stress relief boots had been often used.
In the cable television or inside each tube within a loose pipe cable, individual fibers is going to be colour coded for recognition. Fibers stick to the conference created for telephone wires except fibers are identified separately, not in pairs.
Buffer tubes follow the exact same colour sequence approximately 12 tubes, then pipes 13-24 will replicate the colours using a black stripe (black may have a yellow stripe), tubes 25-36 follows exactly the same colour having an qmaydo stripe, 37-48 use a green stripe, following the same colour code series for that stripe. Tubes containing more than 12 fibers will make use of binder tape to separate fibers into organizations. Ribbon wires stick to this colour sequence also.
For splicing, like colour fibers are usually spliced to ensure continuity of colour rules within a cable run.
