Kuongorora Misiyano Pakati peONU, ONT, SFU, uye HGU.

Kana zvasvika kune mushandisi-parutivi michina mubroadband fiber kuwana, isu tinowanzo kuona mazwi echiRungu akadai seONU, ONT, SFU, uye HGU.Mashoko aya anorevei?Chii chakasiyana?

1. ONU uye ONTs

Iwo makuru ekushandisa marudzi ebroadband optical fiber yekuwana anosanganisira: FTTH, FTTO, uye FTTB, uye mafomu emushandisi-parutivi michina akasiyana pasi pemhando dzakasiyana dzekushandisa.Mushandisi-parutivi midziyo yeFTTH neFTTO inoshandiswa nemushandisi mumwechete, inonzi ONT (Optical network terminal, optical network terminal), uye mushandisi-padivi midziyo yeFTTB inogovaniswa nevakawanda vashandisi, inonzi ONU (Optical Network Unit, optical. network unit).

Mushandisi ataurwa pano anoreva mushandisi anobhadhariswa akazvimirira nemushandisi, kwete nhamba yematerminal anoshandiswa.Semuyenzaniso, iyo ONT yeFTTH inowanzogovaniswa neakawanda materminal mumba, asi mushandisi mumwe chete ndiye anogona kuverengerwa.

2. Mhando dzeONTs

ONTndiyo yatinowanzo kudaidza kuti optical modem, iyo yakakamurwa kuita SFU (Single Family Unit, single family user unit), HGU (Home Gateway Unit, home gateway unit) uye SBU (Single Business Unit, single business user unit).

2.1.SFU

SFU kazhinji ine 1 kusvika 4 Ethernet interfaces, 1 kusvika 2 yakamisikidzwa nharembozha, uye mamwe mamodheru anewo tambo dzeTV.Iyo SFU haina gedhi repamba basa, uye chete terminal yakabatana neEthernet port inogona kufona kusvika paInternet, uye iyo kure manejimendi basa haina simba.Iyo optical modem inoshandiswa mukutanga nhanho yeFTTH ndeyeSFU, iyo isingawanzo kushandiswa ikozvino.

2.2.HGUs

Iwo optical modem ane FTTH vashandisi akavhurwa mumakore achangopfuura ese ari HGU.Kuenzaniswa neSFU, HGU ine zvinotevera zvakanakira:

(1) HGU mudziyo wegedhi, wakanakira network network;nepo SFU chiri chinhu chakajeka chekufambisa, icho chisina magedhi ekugonesa, uye kazhinji chinoda kushandirapamwe kwemidziyo yegedhi senge ma routers epamba mudzimba networking.

(2) HGU inotsigira routing mode uye ine NAT basa, iri layer-3 mudziyo;nepo SFU mhando inongo tsigira layer-2 bridging mode, iyo yakaenzana ne layer-2 switch.

(3) HGU inogona kushandisa yayo yeBroadband dial-up application, uye makomputa akabatana nematerminals enhare anogona kuwana zvakananga Internet pasina kufona;nepo SFU inofanirwa kufona nekombuta yemushandisi kana nhare mbozha kana kuburikidza nerouter yekumba.

(4) HGU iri nyore kune yakakura-chiyero chekushanda nekugadzirisa manejimendi.

HGU kazhinji inouya neWiFi uye ine USB port.

2.3.SBUs

Iyo SBU inonyanya kushandiswa kuwana FTTO mushandisi, uye kazhinji ine Ethernet interface, uye mamwe mamodheru ane E1 interface, landline interface, kana wifi basa.Kuenzaniswa neSFU neHGU, SBU ine kuchengetedzwa kwemagetsi kurinani uye kugadzikana kwepamusoro, uye inowanzoshandiswa muzviitiko zvekunze sekutarisa vhidhiyo.

3. ONU Type

ONU yakakamurwa kuita MDU (Multi-Dwelling Unit, multi-resident unit) uye MTU (Multi-Tenant Unit, multi-tenant unit).

Iyo MDU inonyanya kushandiswa kuwana kwevazhinji vashandisi vekugara pasi peiyo FTTB application mhando, uye kazhinji ine angangoita mana mushandisi-parutivi nzvimbo, kazhinji iine 8, 16, 24 FE kana FE + POTS (yakagadziriswa nhare).

MTU inonyanya kushandiswa kuwana kwevazhinji vashandisi vebhizinesi kana akawanda materminal mubhizinesi rimwechete mune yeFTTB mamiriro.Mukuwedzera kune Ethernet interface uye yakagadziriswa nharembozha, inogonawo kuva neE1 interface;chimiro uye basa reMTU kazhinji hazvina kufanana neaya eMDU.Kusiyana, asi magetsi ekudzivirira kushanda kuri nani uye kugadzikana kwakakwirira.Nekuzivikanwa kweFTTO, mamiriro ekushandisa eMTU ari kuita madiki uye mashoma.

4. Pfupiso

Broadband optical fiber yekuwana inonyanya kutora tekinoroji yePON.Kana iyo chaiyo fomu yemushandisi-padivi midziyo isina kusiyaniswa, mushandisi-parutivi michina yePON system inogona kunzi pamwe chete seONU.

ONU, ONT, SFU, HGU…zvishandiso izvi zvese zvinotsanangura mushandisi-padivi midziyo yekuwana Broadband kubva kumakona akasiyana, uye hukama huripo pakati pawo hunoratidzwa pamufananidzo uri pazasi.
