Dekedaha HUANET EPON OLT 16
EPON OLT waa cajalad is-dhexgal sare leh iyo mid dhexdhexaad ah oo loogu talagalay EPON OLT oo loogu talagalay marin u helidda hawl wadeennada iyo shabakadda xarunta ganacsiga.
Waxay raacdaa heerarka farsamada ee IEEE802.3 ah waxayna buuxisaa shuruudaha qalabka EPON OLT ee YD/T 1945-2006 Shuruudaha farsamada ee shabakadda marin u helka——oo ku salaysan Ethernet Passive Optical Network (EPON) iyo Shiinaha telecom shuruudaha farsamo ee EPON 3.0.
OLT waxay bixisaa 16 dekedood oo EPON ah oo hoos u socda oo leh 1000M, 4*GE SFP, 4*GE COMBO deked iyo 2*10G SFP oo loogu talagalay kor u qaadista. Dhererku waa 1U oo keliya si loo fududeeyo rakibidda iyo kaydinta booska. Waxay qaadataa tignoolajiyada horumarsan, iyadoo bixinaysa xal EPON oo hufan. Intaa waxaa dheer, waxay u badbaadinaysaa kharash badan hawl wadeennada sababtoo ah waxay taageeri kartaa shabakadaha isku-dhafka ah ee ONU ee kala duwan.

Uplink: taageero modules koronto iyo indhaha ah, si dabacsan ayaa loo habeyn karaa iyadoo loo eegayo shabakado kala duwan. Cabbirka: Cajalad 1U ah ayaa keydisa booska, isticmaalka korontada oo hooseeya iyo kharashka oo la keydiyo. Ilaalinta Khadka Indhaha: taageerada si toos ah ayay isu beddeshaa marka khadka la saxo. Kalsooni sare: waxay taageertaa koronto laba jibbaaran (Sahayda korontada ee caadiga ah ee hal-abuurka ah).Faa'iidada
