Mazuva ano, mumaguta emagariro, makamera ekutarisa anoiswa mumakona ese.Tinoona makamera akasiyana-siyana ekucherechedza muzvivako zvakawanda zvekugara, zvivakwa zvehofisi, nzvimbo dzekutengesa, mahotera nedzimwe nzvimbo kudzivirira kuitika kwezviitiko zvisiri pamutemo.
Nekuvandudzwa kwakasimba kwehupfumi uye tekinoroji, kuziva kwevanhu nezvekuchengetedzwa kwekuchengetedza kuri kuramba kuchivandudza, uye zvinodikanwa kuti chero nzvimbo inofanirwa kuve nekuchengetedza kuchengetedza.Nekudaro, kuomarara kwekuvandudzwa kwemaguta kunoita kuti hurongwa hwekutarisisa hwechinyakare hwekupinda modhi husakwanise kuzadzisa zvinodiwa, uye iyo yekutarisa sisitimu inoshandisa PON network yekuwana zvishoma nezvishoma inove yakakurumbira.
Sechinhu chakakosha chekushandisa muPON system, sarudzo yeONU yakakosha.Saka ndeipi ONU iri nani uye kuti ungasarudza sei?
ONU chishandiso chekupedzisira-mushandisi chePON maapplication.Iyo yakakwirira-bandwidth uye inodhura-inoshanda terminal mudziyo unodiwa pakuchinja kubva ku "copper cable era" kuenda ku "optical fiber era".Inoita basa rakakosha mukuvaka network.
ONU is an optical network unit, inoshandisa faibha imwe chete kubatanidza kuhofisi yepakati OLT kupa masevhisi akadai sedata, izwi, uye vhidhiyo.Iyo ine basa rekugamuchira data rakatumirwa neOLT, richipindura kumirairo inotumirwa neOLT, buffer data uye kuitumira kuOLT.Inoda kunzwisiswa kwakanyanya uye iri nyore kushandisa.
MaONU akakamurwa kuita maONU akajairwa uye ONU ane PoE.Iyo yekutanga ndiyo inonyanya kushandiswa ONU mudziyo uye inonyanya kushandiswa ONU.Iyo yekupedzisira iPoE-inokwanisa, ndiko kuti, ine akati wandei PoE ports, kuburikidza iyo yekutarisa makamera anogona kubatanidzwa kuti aite kuti ashande zvakajairwa uye kubvisa yakaoma simba wiring.
Pamusoro pechiteshi chePoE, ONU ine PoE inofanirwa kunge iine PON.Kuburikidza nePON iyi, inogona kubatana neOLT kugadzira network yePON yakazara.
Parizvino, rudzi urwu rweONU nePoE runofarirwa nemakambani ekuongorora mainjiniya.Semuenzaniso, mutengo weONU weSushan Weida wakakwira zvakanyanya, asi unogadzirisa matambudziko mazhinji asina kufanira.Naizvozvo, kana network yePON ikashandiswa muchirongwa chekutarisa, iyo ONU ine PoE basa inogona kusarudzwa.
