Chidule cha Zamalonda:
EPON OLT ndi kaseti kaphatikizidwe kapamwamba komanso kaseti kakang'ono ka EPON OLT kopangidwira anthu ogwira ntchito komanso netiweki yamasukulu. Imatsatira miyezo yaukadaulo ya IEEE802.3 ah ndipo imakwaniritsa zofunikira za zida za EPON OLT za YD/T 1945-2006 Tekinoloje zofunika pa intaneti——zochokera pa Ethernet Passive Optical Network (EPON) ndi China telecom EPON zofunikira zaukadaulo 3.0. EPON OLT mndandanda ali omasuka kwambiri, mphamvu yaikulu, kudalirika mkulu, wathunthu mapulogalamu ntchito, imayenera bandiwifi magwiritsidwe ndi Efaneti luso thandizo bizinesi, chimagwiritsidwa ntchito kwa woyendetsa kutsogolo-mapeto Kuphunzira maukonde, kumanga maukonde payekha, ogwira ntchito campus mwayi ndi kupeza maukonde kumanga.
Pali mitundu iwiri ya mafotokozedwe OLT. OLT imapereka 4/8 downlink 1.25G EPON madoko, 8 * GE LAN Ethernet madoko ndi 4 *10G SFP kwa uplink. Kutalika ndi 1U kokha kuti muyike mosavuta ndikupulumutsa malo. Imatengera ukadaulo wapamwamba, wopereka yankho lothandiza la EPON. Kuphatikiza apo, imapulumutsa ndalama zambiri kwa ogwiritsa ntchito chifukwa imatha kuthandizira maukonde osakanizidwa a ONU.
