Dulmarka alaabta:
EPON OLT waa cajalad is dhexgalka sare iyo awoodda dhexdhexaadka ah ee EPON OLT oo loogu talagalay gelitaanka hawl wadeenada iyo isku xidhka xarunta ganacsiga.Waxay raacdaa IEEE802.3 ah heerarka farsamada waxayna buuxisaa shuruudaha qalabka EPON OLT ee YD/T 1945-2006 Shuruudaha farsamada ee helitaanka shabakad — ku salaysan Ethernet Passive Optical Network (EPON) iyo Shiinaha telecom EPON shuruudaha farsamada 3.0.Taxanaha EPON OLT wuxuu leeyahay furfurnaan aad u wanaagsan, karti weyn, isku hallayn sare, shaqeyn software dhammaystiran, adeegsiga bandwidth hufan iyo awoodda taageerada ganacsiga ee Ethernet, oo si ballaaran loogu dabaqay daboolka shabakadda-dhamaadka hore ee hawlwadeenka, dhismaha shabakadda gaarka loo leeyahay, gelitaanka xarunta ganacsiga iyo dhismaha shabakadda kale ee gelitaanka.
Waxaa jira laba nooc oo qeexan OLT.OLT waxay bixisaa 4/8 downlink 1.25G EPON dekedaha, 8 * GE LAN Ethernet dekedaha iyo 4 * 10G SFP kor u qaadida.Dhererku waa kaliya 1U si sahlan loo rakibo iyo badbaadinta booska.Waxay qabataa tignoolajiyada horumarsan, iyadoo bixisa xal wax ku ool ah EPON.Waxaa intaa dheer, waxay u badbaadisaa kharash badan hawl wadeenada sababtoo ah waxay taageeri kartaa isku xirka isku-dhafka ONU ee kala duwan.
