EPON OLT babban haɗe-haɗe ne kuma matsakaicin iya aiki kaset EPON OLT wanda aka ƙera don samun damar masu aiki da cibiyar sadarwar harabar kasuwanci. Yana bin ka'idodin fasaha na IEEE802.3 ah kuma ya sadu da buƙatun kayan aikin EPON OLT na YD/T 1945-2006 Buƙatun fasaha don samun damar hanyar sadarwa--bisa Ethernet Passive Optical Network (EPON) da buƙatun fasaha na EPON na China telecom EPON 3.0. Jerin EPON OLT yana da kyakkyawan buɗewa, babban ƙarfin aiki, babban aminci, cikakken aikin software, ingantaccen amfani da bandwidth da ikon tallafin kasuwancin Ethernet, yadu amfani da keɓaɓɓen kewayon cibiyar sadarwa na gaba-gaba, ginin cibiyar sadarwa mai zaman kansa, damar harabar kasuwanci da sauran ginin hanyar sadarwa.
