Mazuva ano, mumaguta emagariro, makamera ekutarisa anoiswa mumakona ese.Tichaona makamera akasiyana-siyana ekutarisa muzvivakwa zvakawanda zvekugara, zvivakwa zvehofisi, mashopu, mahotera nedzimwe nzvimbo kudzivirira kuitika kwezviitiko zvisiri pamutemo.
Nekuvandudzwa kwakasimba kwehupfumi uye tekinoroji, kuziva kwevanhu nezvekuchengetedzwa kwekutarisa kuri kuramba kuchiwedzera, uye kutariswa kwekuchengetedza kunodiwa munzvimbo chero ipi zvayo.Nekudaro, kuomarara kwekuvandudzwa kwemaguta kunoita kuti hurongwa hwekutarisisa hwetsika dzekuwana husakwanise kuzadzisa zvinodiwa, uye PON inotambirwa.Iyo yekutarisa sisitimu yekuwana network zvishoma nezvishoma yave yakakurumbira.
Semudziyo wakakosha wekupinda muPON system, kusarudzwa kweONU kwakakosha, saka ndeipi ONU iri nani uye nzira yekusarudza?
ONU ishandiso yevashandisi yePON application uye yakakwirira-bandwidth uye inodhura-inoshanda terminal mudziyo unodiwa pakuchinja kubva ku "copper cable era" kuenda ku "optical fiber era".Inotamba basa rakasimba mukuvaka network.
ONU is an optical network unit, inoshandisa unit fiber kuti ibatane nehofisi yepakati OLT kupa masevhisi akadai sedata, izwi, uye vhidhiyo.Iyo ine basa rekugamuchira iyo data yakatumirwa neOLT, ichipindura kumirairo yakatumirwa neOLT, ichivharira 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 ine PoE basa, ndiko kuti, ine akati wandei PoE interfaces.Iwe unogona kubatanidza makamera ekutarisa kuburikidza neaya mainterface.Ivo vanoshanda zvakajairwa uye vanobvisa yakaoma magetsi ekupa wiring.
Pamusoro pePoE ports, ONUs ine PoE inofanirwa kuve nePON.Kuburikidza nePON iyi, vanogona kubatana neOLT kuti vagadzire network yePON yese.
