Epoxy-Polish Termination - Steps & Best Practices
The Gold Standard
Epoxy-polish connector termination is the traditional field termination method that produces the highest quality endface. It involves injecting epoxy adhesive into the connector ferrule, inserting the prepared fiber, curing the epoxy (with heat or ambient cure), and then polishing the endface through a series of progressively finer polishing films.
This method produces connectors with the lowest loss and best reflectance values. It is the reference standard against which other termination methods are compared.
Detailed Steps
- Prepare the cable - strip jacket, remove strength members, strip buffer/coating
- Clean the bare fiber - use isopropyl alcohol to remove debris
- Mix and inject epoxy - fill the connector ferrule bore
- Insert the fiber - thread through the ferrule until it protrudes from the endface
- Cure the epoxy - use a curing oven (typically 5 - 10 minutes at specified temperature)
- Scribe and break - score the protruding fiber and snap it flush with the ferrule
- Polish - progress through 12 um, 3 um, 1 um, and 0.3 um films
Epoxy-polish termination produces the highest quality connectors with lowest loss. The process involves stripping, epoxy injection, fiber insertion, heat curing, scribing, and progressive polishing. It is the benchmark method for field termination quality.
