The four different versions of ÅngströmLap Ultimas Final Polish Lapping Film (Ultimas-P, Ultimas-U and two Ultimas Flock versions) can address multiple requirements and needs.
Here is a very brief overview of the different types of ÅngströmLap Ultimas Final...
The most direct method to de-gas an unfilled epoxy is to centrifuge. After mixing the epoxy (i.e., in the bi-pack), transfer the epoxy to the final dispensing container, usually a syringe (don’t forget the tip cap). Add the piston to the syringe to capture the...
Fiber Cleaning:
For the epoxy to properly bond to the fiber, the fiber must be clean and free of oils or other contamination. This is usually done by wiping the bare fiber with soft, lint-free wipe and high quality alcohol. Proper cleaning materials and technique...
Determining over polishing of the connector is difficult to gauge. For the most part, manufacturers of connectors specify critical lengths of the end of the ceramic ferrule to the base of the metal flange. This critical length then translates to the correct exposure...
Because most optical fiber is typically UV coated, which acts as a thermal insulator, there is almost no absorption of heat by the fiber. This physically causes many problems with polymer extrusion as differential cooling causes many issues in post-extrusion...
As most connectors use a heat-cure two-component epoxy it’s very important to ensure the proper mix ratio and following the curing time. Some applications require a 3 step curing process (pre-heat, curing, cooling down) to ensure that the epoxy is properly...
While 2.5 grams might seem small, some modern-day applications are very small, and relatively speaking 2.5 grams is a lot of material, much of which ends up as waste. Fiber Optic Center provides epoxy in two-part bi-packs that are typically 2.5 grams.

Contamination within the ferrule bore is wearing the bore, creating larger bore diameter:
Ferrule bore wear is unavoidable over time—as thousands of ceramic ferrules are inserted and removed from a stainless steel fixture, the bore will wear. However,...
The method of applying epoxy into the connector is another source of variability that can greatly affect the correct amount/volume of epoxy into the connector.
The most common method is the hand syringe and special OD needle size (usually a 19 or 20 Ga needle). This...
It is important that the manufacturing site takes preventive measures to help reduce the chance of fiber damage during stripping, and measures to identify such damage, should it exist, before connectorizing.
Such measures may include:
Performing a “bending...
