Dulmarka alaabta:
EPON OLT waa cajalad is dhexgalka sare iyo awoodda dhexdhexaadka ah 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 fiican, awood weyn, isku hallayn sare, hawl software dhammaystiran, ka faa'iidaysi hufan oo faa'iido leh iyo awoodda taageerada ganacsiga ee Ethernet, oo si ballaaran loogu dabaqay daboolka shabakadda dhamaadka-dhamaadka hawlwadeenka, dhismaha shabakada gaarka ah, gelitaanka xarunta ganacsiga iyo dhismaha shabakada kale ee marin u helka.
OLT waxay bixisaa 4 downlink 1.25G EPON dekedaha, 8 * GE LAN Ethernet dekedaha iyo 4*GE sfp indhaha 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.
