Any nicks to the fiber during stripping create an EXTREMELY weak point in the fiber. The transition point where the protective coating ends and the stripped fiber begins is especially prone to damage and is always the weakest part of the entire fiber length of a...
Many mechanical field terminable connectors use the 250 or 245 µm coding to restrain a cleaved fiber inside the back of the shell of the connector, therefore if you have a 900 µm tight buffer you have a need to strip the 900um buffer from The 245um UV coating....
It’s essential to program the PID to maintain tube temperature to the desired set-point while avoiding undershoot/overshoot. Here’s an example of an undershoot/overshoot oscillation. Let’s say you set the temperature at 1700 degrees C, but the PID is not...
From Fiber Optic Connector Cross Sectioning and Analysis observations from “Connector B” notes
Observations: This connector has (1) distinctive fiber fracture at the beginning of the ceramic internal chamfer (photo B.2). I did notice more than usual...
Setting up a new bonding process and need to establish the curing schedule or your production process is set but experiencing fiber movement and need to adjust curing temperature or time, here is a FOC TIP to validate your curing schedule:
Follow the Telcordia...
All steps can be found in the FOC article, How to Develop a Fiber Optic Polishing Process that Produces Consistent Results but here we highlight:
Step 3. Conduct a trial run, following our recommended procedures.
Fiber Optic Center offers Recommended Polishing...
When interpreting APC geometry results in order to modify the polishing process to improve results, it is important to understand Apex Offset - namely, that Apex Offset (for both PC and APC ferrules) is really the result of two components: Angle and Key...
Connector supplies with any quality supply their UPC or pre-angled APC connector ferrules within the Telcordia spec for Radius of Curvature and Apex Offset. Depending on the size of the ferrule and the amount of damage or reforming that needs to been done, this is...
Here are tips and considerations regarding freezing epoxy:
After fabricating the connectors or cable assemblies, the remaining material in the syringe must be frozen right away. A certain amount of pot life will have been used, and freezing does not further impact...
Passive component testers are a combination of firmware and hardware that, as noted earlier, must be correctly configured for your specific product. Many PCTs offer the following features:
Insertion Loss/Return Loss module, which contains light sources and a...
