Why epoxy wicks into the buffer or between the coating and the glass?


QUESTION:


Why does epoxy wick into the buffer or between the coating and the glass?


ANSWER:

An epoxy-based connector needs a tight buffer that will not wick epoxy between the coating and the buffer material. In this fashion where true tight buffers are mechanically in intimate contact with the coating of the fiber and are not applied in a way that could draw the coating away from the glass core and cladding. There can be no small spaces that could allow the epoxy to wick into the buffer or between the coating and the glass.
