1.15.5 Fibre Optic Termination
Fibre termination is the section of fibre from the beginning of the termination boot to the
exposed end of the fibre. This includes all mechanical, electrical and optical parts. No single
part of the fibre termination is replaceable/repairable outside the manufacturing base.
•
Ensure the fibre termination is always kept in a clean environment. If this is not
possible, use the clean termination cover provided.
•
During installation of the fibre, ensure that the protective covers are removed only
when necessary.
•
Keep the fibre termination placed downwards when uncovered and not installed.
•
Do not attempt to dismantle the fibre termination.
•
Always handle the termination by the boot not the optical termination.
•
Care must be taken to prevent damage or contamination of any exposed electrical
contacts.
•
The fibre termination must not be subjected to forces caused by dropping, impacting or
collision by heavy objects.
1.15.6 Fibre Routing
In static applications (i.e. fibre and Focus Head do not move), the fibre must not be bent
greater than the minimum bend radius at any point along the route (refer to Section 1.15.4).
In dynamic applications (i.e. fibre and Focus Head move), the following points of good
practice should be adhered to:
•
The fibre cable should be held off the floor and routed along a path so that the fibre
cable does not bend more than the minimum bend radius at any point along the fibre
cable length throughout the production sequence.
•
The fibre cable should be supported at points along its length to prevent gross
movements under the action of its own weight during the production sequence.
•
At the fibre cable support points, the fibre cable should be held using mechanical parts
which prevent the minimum bend radius being exceeded and which do not result in a
radial compressive force on the fibre cable.
•
The fibre cable should never be pulled tight at any point along its length during the
production sequence.
•
The external surface of the fibre cable should be prevented from rubbing/abrasion at
support points or on any other parts in the workstation (e.g. jigs, fixtures, production
parts, workstation walls, floors, robot parts).
•
Acceleration and deceleration of the fibre cable and Focus Head should be kept to a
minimum consistent with achieving process cycle time.
•
At fibre cable installation and periodically during operation (e.g. once per shift), a dry
run of the production sequence should be made. The fibre cable motion should be
checked to ensure that the fibre routing still complies with the points of good practice
above.
1.15.7 Fibre Removal
When removing the fibre termination from the fibre receiver (input or output), hold the
termination and ease the fibre free. Never jerk the fibre free.
