EPON OLT ke kopanyo e phahameng le k'hasete ea bokhoni bo mahareng EPON OLT e etselitsoeng phihlello ea basebetsi le marangrang a khamphase ea khoebo. E latela litekanyetso tsa tekheniki tsa IEEE802.3 ah mme e kopana le litlhoko tsa thepa ea EPON OLT ea YD/T 1945-2006 Litlhoko tsa Tekheniki bakeng sa marang-rang a phihlello——tse thehiloeng ho Ethernet Passive Optical Network (EPON) le China telecom EPON litlhoko tsa botekgeniki 3.0. Letoto la EPON OLT le na le ho buleha ho hoholo, bokhoni bo boholo, ts'epo e phahameng, ts'ebetso e felletseng ea software, ts'ebeliso e nepahetseng ea li-bandwidth le bokhoni ba ts'ehetso ea khoebo ea Ethernet, e sebelisoang haholo ho sekoaelo sa marang-rang sa opereishene, kaho ea marang-rang a poraefete, phihlello ea khamphase ea khoebo le kaho ea marang-rang a mang a phihlello.
OLT e fana ka likou tse 4 tsa downlink 1.25G EPON, 8 * GE LAN Ethernet ports le 4*GE sfp optical bakeng sa uplink. Bophahamo ke 1U feela bakeng sa ho kenya habonolo le ho boloka sebaka. E amohela theknoloji e tsoetseng pele, e fanang ka tharollo e sebetsang ea EPON. Ho feta moo, e boloka litšenyehelo tse ngata bakeng sa basebelisi hobane e ka ts'ehetsa marang-rang a fapaneng a ONU hybrid.
