Imyaro ya HUANET EPON OLT 16
EPON OLT ni kaseti ifite ubushobozi bwo guhuza ibintu byinshi kandi iciriritse ya EPON OLT yagenewe abakora porogaramu zo kwinjira no gukoresha ikoranabuhanga rya campus.
Ikurikiza amabwiriza ya tekiniki ya IEEE802.3 ah kandi yujuje ibisabwa na EPON OLT by’ibikoresho bya YD/T 1945-2006 Ibisabwa na tekiniki ku muyoboro w’itumanaho——bishingiye kuri Ethernet Passive Optical Network (EPON) na China telecom EPON ibisabwa na tekiniki 3.0.
OLT itanga imiyoboro 16 ya EPON ya 1000M, imiyoboro 4 ya GE SFP, imiyoboro 4 ya GE COMBO na 2 *10G SFP yo gushyiramo imiyoboro. Uburebure ni 1U gusa kugira ngo byoroshye kuyishyiraho no kuzigama umwanya. Ikoresha ikoranabuhanga rigezweho, itanga igisubizo cyiza cya EPON. Byongeye kandi, izigama ikiguzi kinini ku bakoresha kuko ishobora gushyigikira imiyoboro itandukanye ya ONU hybrid.

EPON:OLT ikurikiza amahame ya tekiniki ya IEEE802.3ah na China telecom.(cyangwaYD/T 1475-2006) Ubushobozi: Buri PON ishyigikira imiyoboro igera kuri 64, igikoresho cyose gishyigikira ONU zigera kuri 256 ziri mu buryo bwuzuye. Uplink: ishyigikira module z'amashanyarazi na optique, ishobora gushyirwaho mu buryo bworoshye hakurikijwe imiyoboro itandukanye. Ingano: Kaseti ya 1U izigama umwanya, ikoreshwa ry'ingufu nke kandi izigama ikiguzi. Uburinzi bw'umurongo ugaragara: ubufasha buhita buhinduka iyo umurongo usubitswe. Kwizerwa cyane: ishyigikira umuriro w'amashanyarazi ugizwe n'ibice bibiri (Umuyoboro w'amashanyarazi usanzwe ukoreshwa mu buryo bumwe).Akamaro
