Fiber Optic Cable Manufacturing Process

A Fiber Cable Cutting Machine is intended to cut cables of various diameters and wound them into the appropriate length and annular shape, with the benefits of accurate measurement, a series of cutting and winding, and simple automatic operation. It may adjust lengths, speeds, and numbers to increase manufacturing efficiency. This page will give some basic information on fibre optic cable-cutting machines.

What is a Fibre Optic Cable Cutting Machine?

A fibre optic cable cutting machine is a professional tool used in fibre optic patch cord/pigtail production lines to measure cable length, cut, count, wind, roll, and spray word marking (optional).

Features & Benefits

The qualities and benefits of a fibre optic cable-cutting machine are as follows:

• Cut up to 500m of cable length.
• Optional cable arrangement feature.
• Touch screen for convenient operation.
• High manufacturing efficiency.

Applications

Fibre optic cable cutting machines are used in fibre optic patchcord/pigtail production lines, FTTH, and other applications.

To begin manufacture of any form of patch cord, the cable must be cut to the proper size. This appears to be a straightforward operation, but it takes some caution.

We must be aware of various issues that may arise throughout the fibre cutting procedure if we are not diligent.

Avoid excessive bending. Throughout the cutting operation, we must preserve the bending radius within the cable's specifications. However, we must constantly examine the manufacturer's recommendations.

Never use greater pulling force than advised. Typically, the cable is cut from a spool containing 2 or 4 kilometres of cable. Even while utilising equipment that allows us to easily rotate the reel to retrieve the cable, we must avoid pulling on the outer insulation or jacket. The Fibre Polishing Machine is also practical.

The power element beneath the jacket is aramid yarn, often known as Kevlar. Under that are the primary and secondary buffers, as well as the fibre optic.

If we draw the coil cable through the jacket, it will pass through the aramid yard, which is the strength factor. Stretching is inevitable due to its lack of flexibility. Later, this soft plastic will tend to return to its original place, revealing the Kevlar.

To prevent this, the fibre cutting equipment must unwind the cable automatically when the counting machine pulls.

Still, there must be a system in place to mitigate the impact of the cut's commencement. This mechanism consists of two pulleys: one stationary and one movable. The cable travels through them multiple times, resulting in a cable buffer. This buffer will be used from the moment the unwinder is turned on and will keep up with the cable requirements.

Conclusion

The Fibre Cable Cutting Machine features excellent production efficiency and precision, as well as length and speed settings that are adjustable, automated, and simple to use.

Optical Waveguide Alignment

Precise Optical Fiber Alignment System is required for precise and dependable data transmission in an optical network. Most optical networks contain several optical couplings, and even slight losses at these couplings can result in substantial signal loss and data transfer issues. Minimising coupling losses is crucial in these networks. Prior to assembly or packing of an optical system, good fibre alignment results in the best coupling efficiency and hence the least amount of signal loss. Minimal signal loss reduces power needs, resulting in fewer repeaters, cheaper investment costs, and fewer failures.

A well-characterized input beam is linked into the fibre under test, and a raster scan of the fibre is performed to identify first light, which is the output signal from the fibre that indicates when the laser beam first enters the fibre. Once the initial light is detected, the location of the fibre is modified in a lateral, longitudinal, and angular coordinate system to determine the peak intensity of the output optical signal. A successful fibre alignment solution necessitates the modification of various critical motion parameters utilising a precision motion control device and a search method appropriate for the application.

Key Motion Parameters For Fibre Alignment

When employing motion control systems for Optical Waveguide Alignment System, the motion parameters selected for each axis have a significant impact on the alignment process. The following are the major characteristics to consider when selecting a motion controller for the position of peak power in fibre alignment processes.

Minimum Incremental Motion - The least amount of motion that a gadget can consistently and dependably produce. It should not be confused with resolution, which is calculated using the lowest controller display value or encoder increment. Rather, MIM refers to the controller's real physical performance, which allows for the change of the fibre location while looking for the position where maximal power is reached. While a smaller MIM can align the fibre closer to the maximum peak power, this capability comes at a substantial cost in terms of alignment speed and power increments.

The repeatability parameter describes a motion control system's capacity to achieve a repeatable position. It might be unidirectional or bidirectional. Fibre alignment systems generally have a bidirectional repeatability of 1 µm to a few nm. This characteristic is useful for rapidly determining the peak power location of similar device designs.

Optical Fiber Alignment System is a measure of a motion system's ability to maintain a position within a specific window of time and error. Aligning fibres for assembly processes like bonding is dependent on the fibres' positional stability once the peak power has been determined. Position stability requirements vary from 0.5 µm to a few microns.
