Kuongorora musiyano pakati paAnu, Ont, Sfu, uye Hgu.

Kana zvasvika kune mushandisi-mativi midziyo muBroadband Fiber Access, isu tinowanzoona mazwi eChirungu akadai se Onu, Ont, Sfu, uye Hgu. Izvi zvinoreva sei? Ndeupi mutsauko?

1. Onus naOnts

Mhando huru yekushandisa yemhando dzebrowsband Optical Fiber Access Access inosanganisira: ftto, uye fttb, uye mafomu emidziyo yemushandisi akasiyana mumhando dzakasiyana dzekushandisa. Iyo Mushandisi-Side michina yeTtth network unit).

Mushandisi ataurwa pano anoreva mushandisi anobhadharwa akazvimirira neanoshanda, haasi huwandu hwemagetsi anoshandiswa. Semuenzaniso, iyo Ont yeFTTH inowanzogovaniswa nemararamiro akawanda mumba, asi mumwe chete mushandisi anogona kuverengerwa.

2. Mhando dzeZviripo

OntIzvi ndizvo zvetinonyatsodaidzira modem)

2.1. SFU

SFU kazhinji ine 1 kusvika 4 ethernet interfafaes, 1 kusvika ku2 mbozhanhare mbozha, uye mamwe madzinza ane tambo yeTV Iyo SFU haina imba yegedhi regedhi, uye chete terminal yakabatana neye Ethernet chiteshi chinogona kudiwa kuti uwane iyo Internet, uye iri kure manejimendi basa haina kusimba. Iyo Optical Modem inoshandiswa muchikamu chekutanga cheTFU, iyo isingawanzo kushandiswa izvozvi.

2.2. Hgus

Iyo Optical Modems yakagadzirirwa neFTTTH VANYENGE YAKAVANZWA MUZVIRI MUKADZI All HGU. Kuenzaniswa neSFU, Hgu ane zvinotevera zvakanakira:

. Ipo Sfus is a transpent tripment tripment, iyo isina ganho rekugera, uye kazhinji inoda kushandira pamwe kwemidziyo yeGateway yakadai seyemaimba yekugara mumusha wepamba.

. Nepo SFU mhando chete inotsigira layer-2 inotyisa nzira, iyo yakaenzana neyekuisa-2 switch.

. Ipo SFU inofanirwa kuve yakadhindwa nekombuta yemushandisi kana nhare mbozha kana kuburikidza neyemusha router.

(4) Hgu zviri nyore kune yakakura-chiyero kushanda uye kugadzirisa manejimendi.

Hgu kazhinji anouya neWiFi uye ane USB chiteshi.

2.3. Sbus

Iyo sbu inoshandiswa iyo ftto mushandisi yekuwana, uye kazhinji ine eternet interface, uye mamwe madzinza ane e1 interface, iyo landline interface, kana wifi basa. Kuenzaniswa neSfu uye Hgu, sbu ine zvirinani kudzivirira kwemagetsi kuita uye kugadzikana kwepamusoro, uye kunowanzoshandiswawo mumigwagwa yekunze senge vhidhiyo kuongorora kwevhidhiyo.

3. Onu Type

Onu yakakamurwa muMDU (Multi-testing unit, multi-mugari unit) uye mtu (multin-tenant unit, multant unit, multant unit).

Iyo mDo inonyanya kushandiswa mukana wevashandisi vemugari vemuFTB yekushandisa yeFTTB, uye kazhinji ine kanokwana mbopa-emushandisi-emushandisi

MTU anonyanya kushandiswa mukana wekushandiswa kwevakawanda vebhizinesi kana akawanda maTarminals mune imwechete bhizinesi mune yeFTTB Scenario. Pamusoro peEthernet interface uye yakatarwa runhare, zvinogona zvakare kuve neE1 interface; Chimiro uye basa reMTU kazhinji hazvina kufanana neiya ye mdu. Musiyano, asi kuita kwemagetsi kudzivirira kuri nani uye kusimba kwakakwira. Nezvemunhu mazviri FTTO, mamiriro ekushandisa eMtu ari kuita zvidiki uye zvidiki.

4. Pfupiso

Broadband Optical Fiber Kuwana inonyanya kugamuchira tekinoroji. Kana chimiro chaicho chemidziyo yemushandisi hachina kusiyaniswa, iyo mushandisi-mativi midziyo yeiyo pon system inogona kuenderana neAnu.

Onu, Ont, sfu, izvi zvishandiso zvese zvinorondedzera midziyo yemushandisi yekuwana broadband kupinda kubva akasiyana angles, uye hukama pakati pavo hunoratidzwa mumufananidzo pazasi.
