Mazuva ano, mumaguta evanhu, makamera ekutarisa ari kuiswa pakona imwe neimwe. Tichaona makamera akasiyana-siyana ekutarisa muzvivakwa zvakawanda zvekugara, zvivako zvemahofisi, zvitoro, mahotera nedzimwe nzvimbo kudzivirira kuitika kwezviitiko zvisiri pamutemo.
Nekufambira mberi kuri kuramba kuchiita hupfumi netekinoroji, ruzivo rwevanhu nezvekuchengetedzwa kwekuchengetedza rwuri kuramba ruchiwedzera, uye kutarisa kwekuchengetedza kunodiwa chero kupi zvako. Zvisinei, kuoma kwekuvandudzwa kwemaguta kunoita kuti nzira dzekutarisa dzenzira dzechinyakare dzekuwana ruzivo dzisakwanise kuzadzisa zvizere zvinodiwa, uye PON yave kushandiswa. Sisitimu yekutarisa yekupinda netiweki yave kufarirwa zvishoma nezvishoma.
Semudziyo unokosha wekupinda muPON system, kusarudza ONU kwakakosha, saka ndeipi ONU iri nani uye nzira yekusarudza?
ONU chishandiso chinoshandiswa nevashandisi vePON applications uye chishandiso che terminal chine bandwidth yakawanda uye chinodhura zvishoma chinodiwa pakuchinja kubva ku "nguva ye copper cable" kuenda ku "nguva ye optical fiber". Chine basa guru mukuvaka network.
ONU iyuniti ye optical network, inoshandisa yuniti fiber kubatanidza kuhofisi yepakati yeOLT kuti ipe masevhisi akadai sedata, izwi, uye vhidhiyo. Ine basa rekugamuchira data rinotumirwa neOLT, kupindura mirairo inotumirwa neOLT, kubhafa data uye kuritumira kuOLT. Inoda kunzwisiswa kwakanyanya uye iri nyore kushandisa.
MaONU akakamurwa kuita maONU akajairwa uye maONU ane PoE. Yekutanga ndiyo ONU inonyanya kushandiswa uye ndiyo ONU inonyanya kushandiswa. Yekupedzisira ine basa rePoE, kureva kuti, ine maPoE interfaces akati wandei. Unogona kubatanidza makamera ekutarisa kuburikidza nema interfaces aya. Anoshanda zvakajairika uye anobvisa waya dzemagetsi dzakaoma.
Pamusoro pemaPoE ports, maONU ane PoE anofanira kunge aine PON. Kuburikidza nePON iyi, anogona kubatanidzwa neOLT kuti aumbe network yePON yese.
