The word fiber originated from late Middle English (in the sense ‘lobe of the liver’, (plural) ‘entrails’): via French from Latin fibrafibre, filament, entrails’.

Fiber or fibre:

Fiber and fibre are both different spellings of the same word defined above. Both spellings are many centuries old, and neither spelling was clearly prevalent on either side of the Atlantic until the second half of the 18th century. This was a period in which many British educators began to consider it proper for English words of French and Latin origin to take their more French and Latin forms rather than their more Anglicized forms. Fibre is the French spelling of the word from which the English word is derived, so it was promoted as the standard spelling despite its being unphonetic. The belief that French and Latin should hold sway over English never had much traction in the post-independence United States, and while Americans also favored the French spelling through the 19th century, the more phonetic fiber steadily gained ground through that century until becoming the preferred form around 1910.

Use fiber when;

You belong to America, practice American English or are writing for an audience residing in United States of America.

Use fibre when;

You belong to Europe or its proximal countries where English is spoken, practice British English or are writing for British or European audience.

Both spellings are acceptable and replaceable but be consistent in the spellings in a single article or essay.
