1, modem y'ikoranabuhanga ni ikimenyetso cy'ikoranabuhanga gishyirwa mu bikoresho by'amashanyarazi bya Ethernet, modem y'ikoranabuhanga yabanje kwitwa modem, ni ubwoko bw'ibikoresho bya mudasobwa, iri mu gice cyo kohereza binyuze mu guhindura ibimenyetso bya digitale mu bimenyetso bya analog, naho ku gice cyo kwakira binyuze mu gukuramo ibimenyetso bya analog mu bimenyetso bya digitale.
Igice cy'Umuyoboro w'Amatara (ONU) ni igice cy'umuyoboro w'amatara. ONU igabanyijemo ibice by'umuyoboro w'amatara gikora n'ibice by'umuyoboro w'amatara bidakora. ONU ikoreshwa cyane cyane mu kwakira amakuru yoherezwa na OLT. Uretse akazi ka cat y'urumuri, ONU ifite kandi akazi ko guhindura.
2, onu igabanyijemo ubwoko bwa a, b, c, byose uko ari bitatu ni uburyo bwo kugera kuri optique, ariko kugira ngo abakoresha babone umubare w'imiyoboro, ubwoko bw'imiyoboro buratandukanye, modem ya optique mu by'ukuri ni urwego rwa onu.
Modem y'ikoranabuhanga, izwi kandi nka optical cat, ni igikoresho cy'itumanaho cyohereza ibimenyetso by'ikoranabuhanga ku zindi porotoli binyuze mu itumanaho rya fibre optique. Ni igikoresho cyo kohereza amakuru ku miyoboro minini y'ahantu (LAN), umujyi munini (MAN), na wan (WAN). Iki gikoresho kigizwe no kohereza, kwakira, kugenzura, guhuza, no gutanga amashanyarazi. Gikoresha chip nini, simple circuit, ikoreshwa ry'amashanyarazi make, ubwizerwe bwinshi, ikimenyetso cyerekana ko alarm status ihagaze neza, n'imikorere myiza yo gucunga umuyoboro.
Itumanaho rya fibre optique ryateye imbere vuba cyane rihinduka uburyo bw'ingenzi bwo kohereza amakuru kubera ibyiza byaryo nko gukoresha umurongo munini w'amajwi n'ubushobozi bunini. Kugira ngo itumanaho rigerweho, uburyo bwo guhinduranya no gukuramo amakuru bigomba gukorwa. Kubwibyo, nk'igikoresho cy'ingenzi cya sisitemu y'itumanaho rya fibre optique, modem optique iri kwitabwaho cyane. Hari ubwoko bubiri bwa modulator optique: modulator itaziguye na modulator yo hanze, naho demodulator optique igabanyijemo ubwoko bubiri: ifite amplifier y'imbere yubatswe n'itariho. Modulator itaziguye na demodulator ifite amplifier y'imbere yubatswe nibyo byibandwaho muri uyu mushinga. Uburyo bwo guhinduranya amakuru butaziguye bufite ibyiza byo koroshya, gukoresha amafaranga menshi no koroshya ishyirwa mu bikorwa, mu gihe demodulator ifite amplifier y'imbere yubatswe ifite imiterere yo guhuza cyane n'ingano nto.
Modem y'urumuri ni igikoresho cyo kohereza amakuru gishobora guhuzwa na interineti hakoreshejwe umugozi w'umuyoboro, kimwe n'urumuri rwacu rwa interineti, ariko impera yo hejuru y'urumuri rwa interineti ihujwe n'uruziga, naho impera yo hejuru ya modem y'urumuri ihujwe n'inzira y'urumuri, bityo yitwa light cat. Injangwe ihujwe n'inzira y'urumuri. Impera yo hasi ya onu muri epon/GPON ihujwe n'umukoresha.
1, modem ya optique ni ubwoko bwa onu, ni iy'umukoresha umwe, modem ya optique ishobora kandi kuvugwa ko ari onu ya desktop.
2, onu nyamukuru ni iy'abakoresha benshi, ni ukuvuga ko, umuyoboro w'amashanyarazi ufite imiyoboro ya pon 8 kugeza kuri 24. Modem y'amashanyarazi ifite imiyoboro 1-4 gusa.
Itandukaniro riri hagati ya modem optique na ONU:
Modem y'ikoranabuhanga ikoreshwa cyane cyane iyo abakiriya benshi, cyane cyane iyo bakoresha amakuru yihariye.
Ubwoko bw'ikarita ya modem ya optique na desktop, ubwoko bw'ikarita muri rusange bushyiramo icyumba cy'imashini.
Ubusanzwe, mudasobwa ikoreshwa kuri mudasobwa ikoreshwa mu buryo bwa interineti. ONU ikoreshwa mu gukoresha interineti mu miyoboro y’itumanaho. Itandukaniro rikomeye ni ukuva kuri mudasobwa ikoresha ikarita y’icyumba ivanze n’ikarita y’ikoranabuhanga ikoresha i ...
