Mazuva ano, mumaguta evanhu, makamera ekutarisa ari kuiswa pakona imwe neimwe. Tinoona makamera akasiyana-siyana ekutarisa muzvivakwa zvakawanda zvekugara, zvivako zvemahofisi, zvitoro, mahotera nedzimwe nzvimbo kudzivirira kuitika kwezviitiko zvisiri pamutemo.
Nekufambira mberi kuri kuramba kuchienderera mberi kwehupfumi netekinoroji, ruzivo rwevanhu nezvekuchengetedzwa kwekuchengetedzwa rwuri kuramba ruchikura, uye zvinodikanwa kuti chero nzvimbo ipi zvayo ive nekuchengetedzwa kwekuchengetedzwa. Zvisinei, kuoma kwekuvandudzwa kwemaguta kunoita kuti nzira yekutarisa yetsika yekuwana nzira isingakwanise kuzadzisa zvizere zvinodiwa, uye nzira yekutarisa inoshandisa nzira yePON network iri kuramba ichifarirwa zvishoma nezvishoma.
Semudziyo unokosha wekupinda muPON system, kusarudza ONU kwakakosha. Saka ndeipi ONU iri nani uye ungasarudza sei?
ONU chishandiso chinoshandiswa nevashandisi vePON. Chishandiso cheterminal chine bandwidth yakawanda uye chinodhura zvishoma chinodiwa pakuchinja kubva ku "nguva yetambo yemhangura" kuenda ku "nguva yefiber yemaziso". Chinoita basa guru mukuvaka network.
ONU iyuniti ye optical network, inoshandisa fiber imwe chete 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 inokwanisa PoE, kureva kuti, ine maPoE ports akati wandei, ayo makamera ekutarisa anogona kubatanidzwa nawo kuti ashande zvakanaka uye kubvisa waya dzemagetsi dzakaoma.
Pamusoro pePoE port, ONU ine PoE inofanira kunge iine PON. Kuburikidza nePON iyi, inogona kubatanidzwa neOLT kuti igadzire network yePON yese.
Parizvino, rudzi urwu rweONU nePoE rwunofarirwa nemakambani einjiniya ekutarisa. Semuenzaniso, mutengo weONU weSushan Weida wakakwira zvikuru, asi unogadzirisa matambudziko akawanda asina basa. Saka, kana network yePON ikashandiswa muchirongwa chekutarisa, basa reONU nePoE rinogona kusarudzwa.
