QUESTION:

When you’re setting up your process and determining how much epoxy to dispense into a ferrule, how can you be sure you have the proper fill inside the ferrule?

 

ANSWER:

Here’s a simple tip: Use a scrap piece of 900-micron cable as a dipstick (just as you would use a dipstick to check the oil in a car). Follow these steps:

  1. Inject epoxy according to your procedure.
  2. Take a 900-micron cable and push it all the way into the ferrule until it bottoms out on the rear of the ceramic ferrule. (Note: The cable is not stripped. We’re not concerned with inserting fiber into the ferrule bore, just a piece of 900-micron cable.)
  3. Remove the dipstick, which will be wetted with epoxy.
  4. Check to see if you have the desired 2mm to 3mm of wetness on the cable. If you have more than this, you risk overfilling the ferrule. If you have less, the risk is underfilling.
