Zvitanhatu zvakajairika kukanganisa fiber optic transceivers

Fiber optic transceiver iEthernet transmission media conversion unit iyo inotsinhana kure-kupfupi-yakamonyoroka-peya masaini emagetsi uye kureba-kureba kwemaziso masaini.Inonziwo photoelectric converter (Fiber Converter) munzvimbo dzakawanda.

1. Chiedza cheChibatanidza hachivheneke

(1) Tarisa uone kana mutsetse wefiber wakavhurika;

(2) Tarisa uone kana iyo optical fiber mutsara kurasikirwa yakakurisa, iyo inodarika iyo yekugamuchira iyo midziyo;

(3) Tarisa uone kana iyo optical fiber interface yakabatana nemazvo, iyo yemuno TX yakabatana neiyo iri kure RX, uye iri kure TX yakabatana neRX yeko.(d) Tarisa uone kana iyo optical fiber yekubatanidza yakanyatsoiswa mukati meiyo mudziyo interface, kana rudzi rwejumper ruchienderana nedhizaini, kana rudzi rwemudziyo rwunoenderana neoptical fiber, uye kuti kureba kwechishandiso kunoenderana nedaro.

2. The redunhu Link chiedza hachivhenekeri

(1) Tarisa uone kana network tambo yakavhurika;

(2) Tarisa uone kana rudzi rwekubatanidza ruchienderana: makadhi etiweki uye marouters nemimwe midziyo inoshandisa tambo dze crossover, uye switch, hubs uye zvimwe midziyo inoshandisa tambo dzakatwasuka;

(3) Tarisa uone kana mwero wekutapurirana wemudziyo unoenderana.

3. Yakakomba network packet kurasikirwa

(1) Chiteshi chemagetsi che transceiver uye network network interface, kana iyo duplex modhi yechishandiso chemuchina pamigumo miviri haienderane;

(2) Pane dambudziko neakamonyoroka pair tambo uye RJ-45 musoro, saka tarisa;

(3) Dambudziko rekubatanidza Fiber, ingave iyo jumper yakabatana neyekushandisa interface, ingave pigtail inoenderana nejumper uye coupler mhando, nezvimwewo;

(4) Kunyangwe iyo optical fiber mutsara kurasikirwa inodarika yekugamuchira kunzwa kwemidziyo.

4. Mushure mokunge fiber optic transceiver yakabatanidzwa, migumo miviri haigoni kutaurirana

(1) Iyo fiber yekubatanidza inodzoserwa kumashure, uye iyo fiber yakabatana neTX neRX inochinjana;

(2) RJ45 interface uye chigadzirwa chekunze hachina kubatanidzwa zvakanaka (teerera kune yakananga-kuburikidza uye splicing).Iyo optical fiber interface (ceramic ferrule) haienderane.Mhosva iyi inonyanya kuratidzwa mu100M transceiver ine photoelectric mutual control function, senge APC ferrule.Iyo pigtail yakabatana kune transceiver yePC ferrule haizotauri zvakajairika, asi haizokanganisa iyo isiri-optical mutual control transceiver.

5. Batidza uye dzima chiitiko

(1).Zvingave kuti iyo yekuona nzira attenuation yakakura kwazvo.Panguva ino, mita yemagetsi optical inogona kushandiswa kuyera simba rekuona rekupedzisira kwekugamuchira.Kana iri pedyo nekugamuchira sensitivity range, inogona kunyanya kutongwa sekutadza kwenzira yekuona mukati mehuwandu hwe1-2dB;

(2).Zvingave kuti switch yakabatana kune transceiver yakanganisa.Panguva ino, shandura shanduko nePC, kureva kuti, ma-transceivers maviri akabatanidzwa zvakananga kuPC, uye magumo ose ari PING.Kana ikasaoneka, inogona kunyatso tongwa senge switch.Mhosva;

(3).Transceiver inogona kunge iine mhosva.Panguva ino, unogona kubatanidza migumo yese ye transceiver kuPC (usapfuure nekuchinja).Mushure mezvose zvigumo zvisina dambudziko nePING, tumira faira yakakura (100M) kana kupfuura kubva kune imwe mugumo kuenda kune imwe, uye chengeta Kumhanya Kwayo, kana kukurumidza kunonoka (mafaira ari pasi pe200M anogona kutamiswa kweanopfuura maminitsi gumi nemashanu), inogona kunyatsotongwa sekukundikana kwe transceiver

6. Mushure mekunge muchina waputsika uye wotangazve, unodzokera kune zvakajairika

Ichi chiitiko chinowanzo kukonzerwa nekuchinja.Iyo switch ichaita CRC yekuona kukanganisa uye kureba kwekuongorora pane ese akagamuchirwa data.Kana kukanganisa kwaonekwa, pakiti icharaswa, uye pakiti yakarurama ichaendeswa mberi.

Nekudaro, mamwe mapaketi ane zvikanganiso mukuita uku haagone kuwanikwa muCRC yekuona kukanganisa uye kutarisa kwehurefu.Mapaketi akadaro haatumire kunze kana kuraswa panguva yekutumira.Ivo vanozoungana muine dynamic buffer.(Buffer), haigone kutumirwa kunze.Kana buffer yazara, ichaita kuti switch iparare.Nekuti panguva ino kutangazve transceiver kana kutangazve switch kunogona kudzorera kutaurirana kune yakajairika.
