For accurate and reliable data
transfer in an optical network, a precise fibre alignment with Optical Fiber Alignment System is
necessary. Many optical couplings are present in the majority of optical
networks, and even small (1%) losses can cause significant signal loss and
problems with data transport. In these networks, minimising coupling losses is
essential. A properly aligned fibre produces the highest coupling efficiency
and, thus, the least amount of signal loss before an optical system is
assembled or packed. Power requirements are decreased by little signal loss,
which leads to fewer repeaters, lower investment costs, and fewer failures.
Key Motion Parameters for Fibre Alignment
When employing motion control
systems for fibre alignment, 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 with Optical Waveguide Alignment System.
Minimum Incremental Motion (MIM) - The minimum amount of motion
that a device can consistently and reliably provide. 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. The MIM of a motion controller
might vary from 100 nm to 1 nm. 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 refers to a motion control system's capacity to position itself repeatedly. It might be unidirectional or bidirectional.
Position stability is a measure of a motion system's ability to maintain a position within a specific window of time and error. Optical Fiber Alignment System 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.
