Gall y dechnoleg a ddefnyddir i ddarparu band eang ffeibr cyflym fod yn wahanol o un gyfnewidfa i’r llall. Gall hyd yn oed newid o fewn un ardal. Er enghraifft, gallai cabinet newydd gael ei osod i ddarparu technoleg Ffeibr i’r Cabinet (FTTC) neu gellir darparu ffeibr yn uniongyrchol i’r eiddo, sef Ffeibr i’r Adeilad (FTTP).
The technology used to provide fast fibre broadband may vary from exchange to exchange, and even within exchange areas.  For example, a new cabinet may be installed to provide Fibre to the Cabinet (FTTC) technology or fibre may be provided directly to premises, known as Fibre to the Premises (FTTP).
